DEVICE FOR PERFORMING NUMERIC CONTROL OF MACHINE TOOL

WIPO Patent Application WO/2023/218521

A1

The present invention provides a device for performing numeric control of a machine tool, wherein said device generates an outward-direction cutting action and a return-direction cutting action. In the device for performing numeric control of a machine tool, a tool and a workpiece are caused to move back and forth relative to one another while the tool and workpiece are caused to rotate relative to each other, so that the workpiece is cut by both the outward direction cutting action and the return direction cutting action, the device for performing numerical control of a machine tool comprising: a removal region input unit that analyzes a cutting program and reads the shape of the workpiece removal region to be removed by cutting; a processing criteria input unit that reads the processing criteria for cutting including at least the cutting depth of the tool in the outward direction cutting action and the cutting depth of the tool in the return direction cutting action; and an action generating unit that generates the outward direction cutting action and the return direction cutting action so that, on the basis of the removal region shape and processing criteria, the tool intersects the uncut portion of the removal region, and the intersecting amount does not exceed the outward direction cutting depth and the return direction cutting depth in the processing criteria.
