12. Tool Compensation Functions
12.4 Tool Radius Compensation
179
Operation in compensation mode
Relative to the program path (G00, G01, G02, G03), the tool center path is found from the straight
line/circular arc to make compensation.
Even if the same compensation command (G41, G42) is issued in the compensation mode, the
command will be ignored.
When 4 or more blocks not accompanying movement are commanded continuously in the
compensation mode, overcutting or undercutting will result.
When the M00 command has been issued during tool radius compensation, pre-reading is
prohibited.
