Title:
CUTTING MACHINE AND CUTTING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/176632
Kind Code:
A1
Abstract:
The present invention provides a cutting machine including a cutting machine (1) which comprises a machine body (100) and an NC device (200). The NC device (200) has a tool diameter correction amount calculation unit (201), a processing path calculation unit (202), and a drive control unit (203). The machine body (100) has a processing unit (104) and a tool path control unit (300). When an offset amount (ST) between a control center point (CL) of a tool path (TP) and a center point (CN) of a nozzle (106) is set as a processing condition (CP), the processing path calculation unit (202) generates a tool path control signal (TS) for displacing the control center point (CL) relative to the center point (CN) of the nozzle (106) in the predetermined direction (DT) by the offset amount (ST). The machine body (100) controls the tool path (TP) on the basis of the tool path control signal (TS) so that the control center point (CL) is displaced in the predetermined direction (DT) with respect to the center point (CN) of the nozzle (106).
