Title:
CUTTING MACHINE AND CUTTING METHOD
Document Type and Number:
WIPO Patent Application WO/2020/008779
Kind Code:
A1
Abstract:
A cutting machine (1) that comprises a machine body (100) and an NC device (200). The NC device (200) controls the machine body (100) and has a tool diameter correction amount computation part (201), a processing path computation part (202), and a drive control part (203). The tool diameter correction amount computation part (201) generates tool diameter correction information (TC). The processing path computation part (202) generates a tool diameter correction control signal (TS). The drive control part (203) generates a drive control signal (CS). The machine body (100) has a processing unit (104) and a tool path control part (300). The processing unit (104) moves relative to a workpiece (W) and thereby cuts the workpiece (W). On the basis of the drive control signal (CS), the tool path control part (300) controls a non-circular tool path that corresponds to a cutting tool.
