Tool offset
The parameter setting of TO2(No.13001#1) = 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.
