G42 - Cutter Radius Compensation Right
G42 turns cutter compensation on to the right of the programmed part profile. When G42
is active, the tool path is offset by the tool radius value stored in the tool table. The offset
will be to the right side of the part profile. Refer to Figure 4–14. G42 Cutter
Compensation Right, on page 4 - 29 for an illustration of the tool path with G42.
Default—No
Modal—Yes
Cancels G40 - Cutter Radius Compensation Off (default), G41 - Cutter Radius
Either G00 - Rapid Traverse (default), G01 - Linear Interpolation, or G02/G03 -
Clockwise/Counterclockwise Arc must be active.
Examples—Cutter Compensation
The following examples use the part program below. The figures illustrate the tool path
with G40 and with G42. Notice that the tool travels very close to the part with G40. The
nose radius of the tool programmed in Tool Setup determines the space between the part
and the tool.
