Patent ID: 11958151
Assignee: PICUM MT GMBH
Field: Machine tools (Mechanical engineering)
Classification: CPC B | IPC B

Claim 0:
1. A machine tool, comprising:
(a) a tool head frame,
(b) a tool head,
(c) an axis unit fixed to the tool head frame configured for positioning the tool head in a predefinable position, and
(d) a movement device for moving the tool head frame,
wherein the movement device comprises
(e) a machine frame,
(f) a multipod drive which
(i) has at least three drive elements,
(ii) is arranged in a flux of force between the machine frame and the tool head frame, and
(iii) comprises at least two supporting elements which are selectively lockable in a locked state,
(iv) wherein the multipod drive is mechanically overdetermined by the at least two supporting elements and the at least three drive elements,
wherein the at least three drive elements of the multipod drive each feature a drive element drive for moving the respective drive element, and/or
wherein the at least two supporting elements of the multipod drive each feature a supporting element drive for moving the supporting element, and

(g) a control system designed to automatically carry out a method comprising:
(i) driving the drive element drive of each of the at least three drive elements so that the tool head moves along a predefined first precision trajectory,
(ii) driving the tool head or a first tool that is fixed to the tool head, so that it machines a workpiece without moving the axis unit,
(iii) driving the drive element locking device and the support element locking device so that they lock the at least three drive elements and the at least two supporting elements, and
(iv) driving the axis unit so that
the tool head or
the first tool or
a second tool which is fixed to the tool head,

is moved along a predefined second precision trajectory.
