Title: METHOD FOR THE MACHINING OF WORKPIECES USING A MACHINING CENTER
Abstract:
The present invention relates to a method for the parallel machining of multiple workpieces (381,382), in particular two workpieces, using a machining center (30), wherein the workpieces are clamped rigidly to each other in a set-up area (40) by means of a clamping system (37) and optionally with the aid of a gripping robot (39), are moved along a displacement path (36) into a machining area (32) and are machined simultaneously by means of a plurality of work spindles (241, 242), wherein correction data are generated for each workpiece (381,382) for post-machining, either by measurement of the actual dimensions of each workpiece after each machining by a workpiece measurement device (50) or by a one-time measurement of the deviation of the actual dimensions from reference workpieces on the basis of the clamping in the clamping system (37) by means of a clamping system measurement device (52), and wherein subsequently each workpiece (381,382) is post-machined one after the other by means of one of the two work spindles (241,242) on the basis of the generated correction data in order to thereby correct the deviations from the target dimensions.
