Title:
CUTTING MACHINE AND CUTTING METHOD
Document Type and Number:
WIPO Patent Application WO/2020/008778
Kind Code:
A1
Abstract:
A cutting machine (1) that comprises a machine body (100) and an NC device (200). The NC device (200) 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): recognizes a non-circular tool path (TP) that is included in processing conditions (CP) and corresponds to a cutting tool that cuts a workpiece (W); determines whether a plurality of processing plane formation locations (MPL or MPR) are on the tool path (TP); and, upon determining that the plurality of processing plane formation locations (MPL or MPR) are on the tool path (TP), selects an arbitrary processing plane formation location (MPL or MPR). The processing plane formation locations (MPL or MPR) are locations on the tool path (TP) at which a tool diameter is greatest. The processing path computation part (202) generates a tool diameter correction control signal (TS). The drive control part (203) controls the machine body (100).
