A system (40) is provided for processing a workpiece (44). The system (40) includes a support surface (48) for supporting the workpiece (44) and defining a processing path (P) along which the workpiece (44) may travel relative to the system (40). The system (40) includes at least one tool (64a, 64b, 64c) for performing a process on the workpiece (44) that is movable in a work zone (WZ) along a predetermined length (L) of the workpiece (44) in a direction along the processing path (P). The system (40) includes a movable clamp assembly (80) having opposing clamping pads (84, 88) movable into and out of the work zone (WZ) along the processing path (P) to clamp a portion of the workpiece (44) located in the work zone (WZ) prior to the at least one tool (64a, 64b, 64c) performing a process on the workpiece (44).

A computer-implemented method of planning of the shapes of free-form tool paths (P) for simultaneous two-sided machining of a dental restoration (1) having an individual free-form target geometry from a workpiece (2) by using a dental tool machine (3) having at least two tool spindles each having at least one tool (4) arranged on a different side of the workpiece (2) which is simultaneously movable along an axis (y) relative to the tools (4) thereby imposing a kinematic axis coupling. The method includes a step of determining transformations (T′, T″) of the target geometry by which the kinematic axis coupling is converted into a common coupling parameter for both tools (4); and a step of generating dependent on these transformations (T′, T″) the shapes of the free-form tool paths (P) in which the common coupling parameter is identical in time for all participating tool spindles that are driven simultaneously.

A turret unit for a lathe includes a turret main body M configured to be mounted to a carrier support of the machine tool, and a turret head H mounted to the turret main body M and including a turret disk H2. The turret disk is configured to be rotatable, by a first driving means D1, around a disk axis X which is an axis of rotation of the turret disk H2. The turret unit T includes a second driving means D2 for pivoting the turret head H around a turret axis Y, and the second driving means D2 is an inverted motor.
