Title: Machining method
IPC: B23B29/12
Filed: 1974-08-28
Abstract: 1477168 Methods of machining B GUILLERMIER 28 Aug 1974 [4 Sept 1973] 37680/74 Heading B3T In a method of machining preferably in a lathe an oscillating motion is imposed upon the cutting tool in addition to the normal feed movements imparted by the displacement of the tool slide or saddle whereby improved chipbreaking action and surface finish are achieved. The oscillating movement of the tool is achieved by pivoting the tool holder about an axis perpendicular to the axis of rotation of the workpiece whereby the tool cutting edge moves along a small circular arc from a starting point in which the tool point is moving along path parallel to the axis of the workpiece and hence at a tangent to the circular arc, to a point clear of the workpiece surface. A tool carrier for use in effecting the method of machining is in the form of a body portion 13 from which extend parallel guide members 11, 12 and between which the tool holder 14 is mounted for pivoting about an axis 15 perpendicular to the guide members, the tool holder 14 being held against a stop 20 by spring means 21. The pivoting of the tool holder about the axis 15 and from and against the stop 20 is effected by motor means 23 in the body portion 13 which carries an eccentric 22, 25. In an alternative arrangement the eccentric 34 carries a lobed cam 31 which is coupled to the eccentric by gear coupling 35 and which rotates in the opposite direction to the eccentric. By the selection of the number of lobes, the rotational speed of the motor and the ratio of the gearing of the coupling a wide range of frequency of oscillation of the tool can be achieved. In the former embodiment the frequency of oscillation is only controlled by the speed of rotation of the motor.

A filter comprises a piezo-electric plate 1 having a number of spaced metallic areas 2 on its upper and lower surfaces, the end areas being coupled to leads 4 and serving as transducers and the intermediate areas serving as resonators. To facilitate manufacturing the filter, the areas 2 are formed by successively depositing two films 2a, 2b. The two surfaces of the plate 1 are firstly coated, preferably by electrolytic deposition, with the film 2a, the film is coated with light-sensitive material and a mask is applied accurately defining the required lateral dimensions of the areas 2. This assembly is exposed to light so that the unmasked parts have formed thereon a temporary coating which is insoluble to etching acid. The masked parts of the film 2a are removed by etching and the remaining light-sensitive material is then removed. Thus the lateral dimensions of the areas 2 have been accurately formed, these dimensions determining the filter bandwidth. The thickness of the areas 2 determines the resonant frequency and it is arranged that the thickness of the film 2a is less than the required final thickness. The final thickness is obtained by applying another mask having openings located within the lateral dimensions of the areas 2 and by building up the films 2b by vapour deposition in vacuum. The resonant frequency is continually measured during this deposition and the process is stopped when the required frequency is reached.
