3.1.2 Tool offset
The parameter setting of TO2(No.xxxx#x) = 1 allows you to
activate/deactivate tool offset not by T code only but G code.
The following format combined with T code and G code is used to start tool
offset.
Tool offset ON
T**: Tool offset number
Tool offset number may be specified by
commanding T code for tool selection.
G43: Tool offset ON
G49 Tool offset CANCEL
• Tool offset behavior is the same as the standard type to command it by T
code only.
• While tool offset is specified, changing offset amount does not become
effective immediately. G43 must be newly commanded.
• G43T00 is equivalent to canceling tool offset.
• Set parameter 5002#5 (LGC) to 1 as geometry offset is cancelled by
specifying tool number to 0.
• The specification of tool nose R compensation is the same as the standard
one’s (G40, G41 and G42).
• Tool offset command is the same as the standard type of M system.
