Abstract:
A cutting body for a metal-working machine tool includes a cutting portion extending from a body portion. The body portion is configured to fine-tune the position of the cutting portion. The body portion includes an inner sub-portion and an outer sub-portion disposed between the inner sub-portion and the cutting portion. The outer sub-portion includes adjacent first and second sections. The first section is configured to elastically bend, extends between the inner sub-portion and the cutting portion, and comprises a face adjacent the second section. The second section includes a biasing surface and a biasing sub-portion configured to hold a biasing member. When the biasing sub-portion is moved due to biasing of the biasing member against the biasing surface, the first section is configured to bend and thereby change position of the cutting portion extending therefrom and allow fine-tuning thereof.

     SUMMARY OF THE INVENTION 
     In accordance with a first aspect of the subject matter of the present application, there is provided a cutting body for a metal-working machine tool for chip removal configured for fine-tuning of the position of a cutting portion thereof. 
     More precisely, the cutting body can comprise a body portion, a cutting portion extending from the body portion, and a biasing member; the body portion comprising an inner sub-portion and an outer sub-portion disposed between the inner sub-portion and the cutting portion; the outer sub-portion comprising adjacent first and second sections; the first section extending between the inner sub-portion and the cutting portion, and comprising a face adjacent the second section; the second section comprising a biasing surface extending transverse relative to the first section&#39;s face, and a biasing sub-portion holding the biasing member and integrally connected to the first section&#39;s face; the first section being configured to elastically bend upon actuation of the biasing member due to application of force on the biasing surface by the biasing member, thereby changing position of the cutting portion for fine-tuning thereof. 
     It will be understood that the first section can be configured to bend by, e.g., it having a smaller thickness than adjacent portions of the cutting body. Such adjacent portion can be the inner sub-portion. 
     In accordance with another aspect of the subject matter of the present application, there is provided a cutting body comprising a cutting portion extending from a body portion which is configured to fine-tune the position of the cutting portion; the body portion comprising an inner sub-portion and an outer sub-portion disposed between the inner sub-portion and the cutting portion; the outer sub-portion comprising a section configured to elastically bend and a biasing sub-portion which is configured to hold a biasing member and is located closer to the cutting portion than the section configured to elastically bend. 
     In accordance with yet another aspect of the subject matter of the present application, there is provided a cutting body comprising a cutting portion extending from a body portion which is configured to fine-tune the position of the cutting portion; the cutting portion only being connected to the body portion on one side thereof, to allow bending of the cutting portion without affecting other portions of the cutting body; the body portion further comprising a biasing groove that extends below the cutting portion to further allow bending thereof, and a biasing sub-portion and biasing surface disposed on opposing sides of the biasing groove; the biasing sub-portion and biasing surface being configured to cooperate with a biasing member to cause said bending. 
     In accordance with still another aspect of the subject matter of the present application, there is provided a cutting body, comprising a body portion having a biasing sub-portion and a biasing surface; a cutting portion extending from the body portion in a first direction; and a biasing member having an end surface, the biasing member retained by the biasing sub-portion with the end surface of the biasing member contacting the biasing surface, wherein: the biasing member applies a first force against the biasing surface in a direction generally opposite to the first direction; and the biasing member applies a second force against the biasing sub-portion in a transverse direction to thereby change a position of the cutting portion for fine-tuning thereof. 
     In accordance with a further aspect of the subject matter of the present application, there is provided a machine tool comprising a plurality of cutting bodies. Each of the cutting bodies can have any of the features described hereinabove and below. 
     In accordance with still a further aspect of the subject matter of the present application, there is provided a method of fine-tuning a cutting body having any of the features mentioned hereinabove or below. The method can comprise the steps of:
         moving the biasing sub-portion relative to the biasing surface via movement of the biasing member in a first direction, thereby causing the first section to bend in a first calibration direction and change a position of the cutting portion extending therefrom;   halting movement of the biasing member in a first direction when a predetermined angle is reached;   moving the biasing member in a second direction, opposite to the first direction, allowing elasticity of the first section to move the cutting portion in a second calibration direction which is opposite to the first direction; and   halting movement of the biasing member when a desired fine-tuning position is reached.       

     It will be understood that the above-said is a summary, and that any of the aspects above may further comprise any of the features described in connection with any of the other aspects or described hereinbelow. Specifically, the following features, either alone or in combination, may be applicable to any of the above aspects:
     A. A cutting body can be formed with a recess can be formed between adjacent cutting portions.   B. A cutting portion can be surrounded by recesses on both sides thereof to allow independent bending. A cutting portion can be associated with a biasing groove that extends therebelow along a majority of the cutting portion to provide uniform bending of the cutting portion. A cutting portion can be associated with an anchoring sub-portion which can be configured to restrict bending movement of the cutting portion.   C. A second section can be formed with a gap located between a biasing sub-portion and a biasing surface. The gap can be part of an elongated biasing groove. The biasing groove can extend tangentially, for example, in a case where the body portion is disc-shaped. The second section can comprise an anchoring sub-portion connected between an inner sub-portion and the biasing sub-portion, for regulating or restricting bending movement of an associated cutting portion.   D. A biasing sub-portion can be closer to the cutting portion than the biasing surface. The biasing sub-portion can be formed with a threaded bore directed towards the biasing surface and having a bore central axis extending through a center thereof. The biasing sub-portion can be configured to hold a biasing member. The threaded bore and/or the biasing member can comprise a rotation inhibitor arrangement. It has been found that such arrangement can assist in maintaining a precise desired position, even in, but not limited to, usage of biasing members in rotary tools such as the one exemplified below. It has been found that the rotation inhibitor arrangement can be a patch secured to the threading thereof. It is believed that the use of patches to prevent movement of a biasing member configured to fine-tune a cutting body of a metal-working tool, in particular a rotating tool, is heretofore unknown. The rotation inhibitor arrangement can be threading of the threaded bore, the threading being configured with a pitch smaller than that defined by the standard DIN 913 ISO 4026.   E. A first direction can be defined from the body portion to the cutting portion. More precisely, the first direction can be coaxial with a central axis of a biasing sub-portion. A second direction can be defined as perpendicular to the first direction. In embodiments where a body portion is elongated, the first direction can be a longitudinal direction. In embodiments where a body portion is disc-shaped, the first direction can be a radial direction. Each recess between adjacent cutting portions can extend parallel to the first direction. A biasing groove can extend in the second direction. In embodiments where the body portion is disc-shaped, the direction of the biasing groove can be perpendicular to both the first direction and an axial direction, i.e., a tangential direction.   F. A body portion can be disc-shaped. In such case each recess between adjacent cutting portions can extend radially. A threaded bore can extend radially. The bore central axis of the bore can form an angle α with the biasing surface between 88.5° to 92.5°. In an unbiased state, the bore central axis can form an obtuse angle α with the biasing surface. In such case a preferred obtuse angle can be 91.5°. In an unbiased state, the bore central axis can form an acute angle α with the biasing surface. In such case a preferred acute angle can be 88.5°. It will be understood that according to some embodiments, such as the example shown below, an obtuse angle is preferred since actuating the biasing member to contact the biasing surface closer to the first section can result in a smaller force than would be the case if the biasing member contacted the biasing surface further from the first section. Accordingly the cutting body is less sensitive to actuation of the biasing member and may be easier to accurately tune. However, in embodiments where the cutting body is less bendable (e.g. due to different thicknesses or materials used), it is envisioned that an acute angle α may be preferred.   G. The cutting portion can be only connected to the body portion on one side thereof, to allow bending of the cutting portion without affecting other portions of the cutting body. The body portion can comprise an elongated biasing groove that extends below the cutting portion to further allow localized and uniform bending of the cutting portion The biasing sub-portion and the biasing surface can be disposed on opposing sides of the biasing groove.   H. Any or each of the cutting bodies can abut at least one adjacent cutting body.   I. A body portion can be disc-shaped and have a body central axis.   J. A first force can be applied by a biasing member in a generally radially inward direction.   K. A second force can be applied by the biasing member, via the biasing sub-portion, in a generally axial direction.   L. A method of fine-tuning can comprise, before step (a) mentioned above, a step of securing adjacent cutting bodies in an abutting manner to each other.   M. A method of fine-tuning can comprise, moving the biasing sub-portion relative to the biasing surface by moving the biasing sub-portion away from the biasing surface.

     DETAILED DESCRIPTION 
     In the following description, various aspects of the subject matter of the present application will be described. For purposes of explanation, specific configurations and details are set forth in sufficient detail to provide a thorough understanding of the subject matter of the present application. However, it will also be apparent to one skilled in the art that the subject matter of the present application can be practiced without the specific details presented herein. 
     Reference is made to  FIGS. 1A to 1C , which show a tool  10  for metal cutting operations, which in this non-limiting example is a rotary tool, comprising a plurality of cutting bodies  12 , and a standard rotating/fastening tool  11  ( FIG. 1A ), which in this example can be an Allen key, for fine-tuning the cutting bodies  12 . 
     In this non-limiting example, there are five cutting bodies  12  disposed directly adjacent to each other (as shown in  FIG. 1C , the tool  10  is free of gaps between adjacent cutting bodies  12 ). More precisely, each cutting body  12  can be secured in an abutting manner to each adjacent cutting body  12 . Such arrangement can allow multiple closely spaced cuts to be made. 
     A central aperture  18  can be formed in the center of the cutting body  12 . A body central axis A C  can pass through the middle or mid-point  20  of the cutting body  12 , which in this example can coincide with a mid-point of the central aperture  18 . In embodiments where the cutting body  12  is configured to be used in a rotating tool, the cutting body  12  can be configured for rotation about the body central axis A C . 
     Referring also to  FIG. 2B , each cutting body  12  can comprise a body portion  14 , a cutting portion  16  extending radially-outward therefrom, and a biasing member  17  ( FIG. 2C ) respectively associated with, and configured for orienting, each associated cutting portion  16 . 
     In the specification and the claims, references to directions including the terms ‘axial’ and ‘radial’ are made relative to the body central axis A C . 
     The cutting portions  16  can be circumferentially spaced, equally or otherwise, about the body portion  14 . The cutting portions  16  can be disposed in a staggered arrangement with respect to the cutting portions  16  of adjacent cutting bodies  12  (best shown in  FIG. 1A ). Each cutting portion  16  can be unconnected to or, stated differently, spaced apart from adjacent cutting portions  16 . More precisely, each cutting body  12  can be formed with a recess  19  ( FIG. 2A ) formed between adjacent cutting portions  16 . Each recess  19  can extend to the body portion  14  and can extend, in this example of a disc-shaped tool, in a radial direction D R . Each cutting portion  16  can be configured for bending motion independent of position of adjacent cutting portions  16 . 
     Each cutting portion  16  can have a planar shape (e.g., as shown in the side view in  FIG. 1C ). 
     Referring, in particular, to  FIG. 2C , each cutting portion  16  can extend from the body portion  14  and terminate at an opposing top end  16 A. Each cutting portion  16  can have axially facing first and second major side surfaces  16 B,  16 C, which can be parallel to each other and can extend from the body portion  14  to the top end  16 A. Each cutting portion  16  can have a magnitude of thickness T C  ( FIG. 2B ), between the first and second side major surfaces  16 B,  16 C. 
     Referring in particular to  FIG. 2A , each cutting portion  16  can have first and second minor side surfaces  16 D,  16 E. The first and second minor side surfaces  16 D,  16 E can be located on opposing sides of an associated cutting portion  16 . The first and second minor side surfaces  16 D,  16 E can each extend between the body portion  14 , the top end  16 A and the first and second major side surfaces  16 B,  16 C. 
     As best shown in  FIG. 1B , in this non-limiting example, each cutting portion  16  can further have an insert  22  secured thereto in a removable manner. Each insert  22  has a cutting edge  24  disposed peripherally along the cutting body  12 . It will be appreciated that the subject matter of the present application is not limited to any particular type of cutting portion  16 , insert  22  or cutting edge  24 . In any case, according to some embodiments, each cutting portion  16  is formed with a pocket  26  ( FIG. 2A ), to which the insert  22  is mounted. 
     As best shown in  FIG. 2A , the body portion  14  can be disc-shaped. 
     As best understood from  FIG. 2B , the body portion  14  can comprise an inner sub-portion  39  and an outer sub-portion  40  extending between the inner sub-portion  39  and each of the cutting portions  16 . 
     As can be understood from  FIGS. 2A and 2B , the inner sub-portion  39  can have a cylindrical shape. 
     As best shown in  FIG. 2A , the inner sub-portion  39  can be defined between an inner peripheral end  28 , an outer peripheral end  29 , and first and second side surfaces  30 ,  32  extending therebetween. 
     Referring to  FIG. 2B , the inner sub-portion  39  can have a magnitude of radial depth D H . Such radial depth D H  can be defined between the inner peripheral end  28  and the outer peripheral end  29 . 
     As in the present example, the inner peripheral end  28  can be formed with recesses  34  ( FIG. 2A ) configured for connection with a rotating shaft (not shown). However, per application, the inner sub-portion  39  can have a solid or uniform construction, stated differently, the inner sub-portion  39  can be devoid of recesses or hollow areas. 
     The first and second side surfaces  30 ,  32  can extend perpendicular to the body central axis A C  (in this example in a radial plane including the radial direction D R ). 
     Referring now to  FIG. 2C , the outer peripheral end  29  can be disposed at an intersection with the outer sub-portion  40 . 
     The outer sub-portion  40  can comprise adjacent first and second sections  40 A,  40 B. 
     Referring also to  FIG. 2B , the first section  40 A can extend between the inner sub-portion  39  and the cutting portion  16 . The first section  40 A can have opposing first and second faces  40 A 1 ,  40 A 2 . 
     The first face  40 A 1  can extend between the inner sub-portion&#39;s first side surface  30  and the first major side surface  16 B of the associated cutting portion  16 . The second face  40 A 2  can extend from the second major side surface  16 C of the associated cutting portion  16  toward the inner sub-portion  39 . 
     The second section  40 B can be located radially outward from the inner sub-portion  39  and axially outward from the first section  40 A. The second section  40 B can comprise a biasing sub-portion  36 A and a biasing surface  35  which faces in a generally radially outward direction. The second section  40 B can also comprise an anchoring sub-portion  36 B ( FIG. 2A ). 
     Further to defining the biasing surface  35 , a more precise definition of the first section  40 A can be that it extends from the inner sub-portion  39 , which ends adjacent the biasing surface  35 , until an associated cutting portion  16 , which starts adjacent to an upper edge  37 A of the biasing sub-portion  36 A. 
     The biasing sub-portion  36 A can extend from the second face  40 A 2  of the first section  40 A. The biasing sub-portion  36 A can extend between the upper edge  37 A and a lower edge  37 B thereof. The upper and/or lower edges  37 A,  37 B can extend perpendicular to the second face  40 A 2 . The upper edge  37 A can be located further than the lower edge  37 B from the body central axis A C . The lower edge  37 B can terminate at a location spaced apart from the biasing surface  35 . Stated differently, there can be a gap  37 C between the lower edge  37 B and the biasing surface  35 . The biasing sub-portion  36 A can be formed with an internally threaded bore  36 A 1  ( FIG. 2B ). The biasing sub-portion  36 A can be elongated (best shown in  FIG. 2A , in which an exemplary airfoil-like shape is shown). Such elongation can extend from the recess  19  associated with the second minor side surface  16 E of the associated cutting portion  16  in a direction towards another one of the recesses  19  which is associated with the first minor side surface  16 D of the same cutting portion  16 . The elongation can extend along a majority of the distance between the recesses  19  of an associated cutting portion  16 . 
     The lower edge  37 B can be flat. The flat lower edge  37 B can extend in a direction tangential (D T ) to the body central axis A. 
     The upper edge  37 A can be curved. The curved upper edge  37 A can extend parallel with a portion of the biasing surface  35 . 
     A portion of the biasing surface  35  aligned with the threaded bore  36 A 1  can coincide with or, stated differently, co-constitute a portion of the outer peripheral end  29 . 
     A bore central axis A B  ( FIG. 2B ) can extend through the center of threaded bore  36 A 1 . The threaded bore  36 A 1  can extend radially. Stated differently, the bore central axis A B  can intersect or can extend proximate to the center  20  of the cutting body  12 . In an unbiased state, i.e., when the biasing member  17  is not applying forces to the biasing surface  35 , the biasing surface  35  can form an angle α (shown in  FIG. 2B , i.e., such angle can be seen in a side view) with the bore central axis A B  of the threaded bore  36 A 1 . The angle α can be between 88.5° to 92.5°, depending on a desired application. In this non-limiting example, the angle α is 91.5° (the slant of the biasing surface  35  in  FIGS. 2B and 2C  has been exaggerated for ease of visibility). An obtuse angle, for example 91.5°, is believed to be advantageous over an acute angle, for example 88.5°, due to reduced sensitivity of the cutting portion  16  upon adjustment of the biasing member  17 . However, there may be cases where such amplified sensitivity is desired. Accordingly, it is preferred that the angle fulfill the condition 88.5°&lt;α&lt;92.5°. Similarly, while an angle of 90° is feasible, it is preferred that the angle α is other than 90° (α≠90°), which may affect force needed to initially move the biasing member  17 . Regardless of the angle α in the unbiased state, the bending motion according to some embodiments can allow a range of movement of the associated cutting portion  16  of between 88.5° to 92.5°. Such range can be sufficient for fine-tuning while requiring a small number of turns of the fastening tool  11 . 
     The second section  40 B can be formed with a biasing groove  42 . The gap  37 C can constitute a part of the biasing groove  42 . The biasing groove  42  can have a first end  42 A, which can open out to the recess  19  associated with the minor second side surface  16 D of an associated cutting portion  16 . The biasing groove  42  can have a closed second end  42 B, terminating between the recess  19  associated with the minor first side surface  16 E of an associated cutting portion  16  and the inner sub-portion  39  of the body portion  14 . The biasing groove  42  can extend in the tangential direction D T . The biasing groove  42  can be defined between the lower edge  37 B ( FIG. 2B ) of the biasing sub-portion  36 A, the biasing surface  35  ( FIG. 2C ), and the second face  40 A 2  ( FIG. 2B ) of the first section  40 A. 
     It will be understood that the biasing groove  42  can be configured to provide localized flexibility to the cutting body  12 . More specifically, the biasing groove  42  provides flexibility to the outer sub-portion  40  relative to the inner sub-portion  39 , at an area disposed between the inner sub-portion  39  and an associated cutting portion  16 . The elongation of the biasing groove  42  can correspond to an elongation of an associated cutting portion  16 , to allow uniform bending movement to the entire associated cutting portion  16 . 
     The recesses  19  can also allow localized flexibility. The recesses  19  can serve to isolate the cutting portions  16  from each other. Consequently, the recesses  19  can allow uniform bending movement to the entire associated cutting portion  16 . Notably, the recesses  19  can be formed between the cutting portions  16  and can also be formed in the outer sub-portion  40 . 
     The anchoring sub-portion  36 B ( FIG. 2A ) can extend from the outer peripheral end  29  to the biasing sub-portion  36 A thereby forming a linkage or neck therebetween. The anchoring sub-portion  36 B can be defined between adjacent biasing grooves  42  and an associated recess  19  adjacent thereto. The anchoring sub-portion  36 B can regulate bending movement of an associated cutting portion  16 . Stated differently, the anchoring sub-portion  36 B can limit bending movement of an associated cutting portion  16 . Such regulation or limitation on the bending can counterbalance the elements which are designed to increase flexibility. 
     It will be understood that each biasing groove  42  could feasibly extend from the first end  42 A and open out to an adjacent biasing groove  42 , i.e., being formed free of a second end  42 B. However the provision of an anchoring sub-portion  36 B can possibly be advantageous for restricting overextension (i.e., excessive bending) of an associated cutting portion  16 . 
     The biasing member  17 , in this non-limiting example, can be a screw with external threading  17 C. It will be understood that the biasing member could be other than a screw, for example, a non-threaded lever or clamp member. The biasing member  17  can have a flat end  17 A for engagement with the biasing surface  35 . The biasing member  17  can have a length shorter than a length between the upper edge  37 A and the biasing surface  35 , so that it does not protrude from the biasing sub-portion  36 A, in a direction towards an associated cutting portion  16 , when mounted to the threaded bore  36 A 1 . It is believed to be possibly advantageous for the biasing member  17  to be configured with a rotation inhibitor arrangement  17 B. Such rotation inhibitor arrangement  17 B can be, for example, a nylon patch secured to the external threading  17 C of the screw, at least where the part which is to engage the threaded bore  36 A 1  during a cutting operation. Such patch can be configured to inhibit undesired rotation of the biasing member  17  in the threaded bore  36 A 1  during cutting operation of the associated cutting body  16 . A suitable example patch is sold by the Bossard Group under the trade name Tuflok®. The patch could alternatively, or additionally, be applied to the threaded bore  36 A 1 . Alternatively, such rotation inhibitor arrangement  17 B could be the biasing member  17  having threading with a small pitch, i.e., pitch smaller than that defined by the International Organization for Standardization (ISO), for example smaller than that defined by the standard DIN 913 ISO 4026. 
     In operation, the biasing member  17  can be inserted in the threaded bore  36 A 1 . The biasing member  17  can be rotated via the tool  11  ( FIG. 1A ) in the threaded bore  36 A 1  until it touches the biasing surface  35  but does not apply force thereto, i.e., the cutting body  12  being in an unbiased state. During adjustment for a cutting operation, every biasing member  17  can initially be rotated further into the threaded bore  36 A 1  so that it applies force to the biasing surface  35 . As the first section  40 A is more flexible than the inner sub-portion  39 , which in this non-limiting example is a result of the magnitude of thickness T C  (of the first section  40 A) being smaller than the magnitude of radial depth D H  (of the inner sub-portion  39 ), the first section  40 A bends in the direction D B  ( FIG. 2C ; the bending not being shown). The initial biasing is to a predetermined maximum bending angle, which in this non-limiting example can be the end of a bending range, for example α=92.5°. Each cutting portion  16  can then be calibrated to a desired position by rotating the biasing member  17  in an opposite direction until a desired bending angle between the unbiased state and the maximum bending angle is reached, which in this non-limiting example is 91.5° ( FIG. 2B ). 
     It will be understood that in a case where the unbiased state has an acute angle, such as 88.5°, the initial rotation can be to a predetermined maximum bending angle of 90° and the desired position can be achieved by rotating the biasing member  17  in an opposite direction until a desired bending angle between the unbiased state of 88.5° and the maximum bending angle is reached. 
     Notably, in the examples above, elasticity of the material of the first section  40 A causes the first section  40 A to revert to the desired bending angle from the initial maximum bending angle. 
     It will be understood that each cutting body  12  can be made of an elastic material, for example steel. However, it will be understood that, in a case where a cutting body is made of a plurality of materials, at least the body portion  14 , and more specifically, at least the first section  40 A thereof, is preferably made of an elastic material. 
     A possible advantage of the radial orientation of the threaded bore  36 A 1  (best seen in  FIG. 1C ) can be ease of access to rotate a biasing member  17  disposed therein, as a radial direction is more easily viewed and/or accessible than other directions. Stated differently, the subject matter of the present application can allow a plurality of cutting bodies to be mounted or packed directly adjacent to each another and to be adjusted while in this position. 
     It will be understood that feasible alternative arrangements could be, for example, the threaded bore  36 A 1  could be slanted with respect to the second face  40 A 2  or cutting portion  16 . Similarly, the axis A B  could be slanted with respect to the second face  40 A 2  or cutting portion  16 , and the biasing surface  35  could be, for example, perpendicular to the second face  40 A 2  or cutting portion  16 . 
     In this non-limiting example, the tool  10  is a so-called slotting-cutter, configured for simultaneously cutting a plurality of slots or grooves, and can also be configured to carry out simultaneous multiple parting of a workpiece, as desired. However, it will be appreciated that other types of rotary tools, or non-rotary tools, in particular of the type having multiple blades, could also constitute a tool, or cutting body, in accordance with the subject matter of the present application. It will be understood that names of elements and directions described which relate to a rotary cutting portion or tool would be changed for a non-rotary cutting portion or tool, mutatis mutandis. For example a radial direction mentioned above may be a first direction or longitudinal direction for an elongated blade-shaped tool. In all such cases, the biasing member applies a first force on the biasing surface in one direction, and applies a second force against the biasing sub-portion in a transverse direction to thereby change a position of the cutting portion for fine-tuning thereof. 
     Notably, the biasing member  17 , in the non-limiting example shown, is distinct from any clamping mechanism of the cutting portion  16 , i.e., relating to the cutting insert  22  or the cutting edge  24 . More precisely, the cutting portion  16  is devoid of biasing elements or portions. Accordingly, there is no thickness limitation of the cutting portion  16  caused by a biasing elements or portions such as a threaded bore, biasing member or portion, on the cutting portion  16 . A possible advantage of this arrangement can be that a cutting portion is not limited to a width required for accommodating biasing elements and an extremely thin cut or plurality of cuts, especially in a case where there are multiple adjacent cutting bodies, can be achieved. It will be understood that the orientation of the threaded bore  36 A 1  (i.e., in this example being radially oriented), can allow an operator access even in the compact arrangement shown. 
     Further, in this non-limiting example, one or more of (a) the biasing member  17 , (b) the biasing surface  35 , and (c) the threaded bore  36 A 1  are disposed between an associated cutting portion  16  and the center  20  of the cutting body  12 . Stated differently, the biasing member  17  and/or the biasing surface  35  and/or the threaded bore  36 A 1  are located closer to the center  20  of the cutting body  12  than the cutting portion  16 . 
     Another possible advantage of the subject matter of the present application is that a cutting body is provided which is configured to be flexible at an intersection of a cutting portion and body portion thereof for allowing adjustment of the cutting portion position. In addition to the flexible region, the cutting portion can have an anchoring arrangement to regulate the flexibility, stabilize or restrict excessive movement of the cutting portion. 
     While the subject matter of the present application has been described with reference to one or more specific embodiments, the description is intended to be illustrative as a whole and is not to be construed as limiting the subject matter of the present application to the embodiments shown. It is appreciated that various modifications may occur to those skilled in the art that, while not specifically shown herein, are nevertheless within the scope of the subject matter of the present application.
