12. Tool Offset Functions
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.
