To program Cuer Compensaon to the le of the programmed tool path, program: G41 D~
To program Cuer Compensaon to the right of the programmed tool path, program: G42 D~
Word Definition
D~ Tool number associated with the diameter oset to be applied
The D word is oponal; if there is no D word the radius of the currently loaded tool is used (if no tool
is loaded and no D word is given, a radius of 0 is used).
If supplied, the D word is the tool number to use.
To start Cuer Compensaon to the le of the part prole, use G41. G41 starts Cuer Compensaon
to the le of the programmed line as viewed looking down on the mill.
To start Cuer Compensaon to the right of the part prole, use G42. G42 starts Cuer Compensaon
to the right of the programmed line as viewed looking down on the mill.
The lead in move must be at least as long as the tool radius. The lead in move can be a rapid move.
Operator M100-M199 commands are allowed when Cuer Compensaon is on.
It is an error if:
The D number is not a valid tool number or 0
Cuer Compensaon is commanded to turn on when it is already on

G41.1 and G42.1 funcon the same as G41 and G42 with the added scope of being able to ignore
the tool table and to program the tool diameter. The L word defaults to 0 if unspecied.
It is an error if:
The L number is not in the range from 0 to 9 inclusive
Cuer Compensaon is commanded to turn on when it is already on
