2.11.3 Amount of Cutter Compensation
In the cutter compensation C, the value of the tool nose radius is used as the
value of the cutter compensation.
Used as cutter radius offset amount
The character of the cutter compensation number used in the AI HPCC / AI
NANO HPCC mode is displayed in reverse as the following figure.
ctual cutter compensation number
2.11.4 Tool Geometry and Wear Offset
When the option of the tool geometry and wear offset is effective, an actual offset
amount becomes the summation of the geometry and wear offset amount of
commanded D number. A different offset number cannot be specified in
geometry and wear.
2.11.5 Corner Offset Circular Interpolation(G39)
Specify the corner offset circular interpolation (G39) for the outside of a curve. If
this command is specified for the inside of a curve, an excessive cut can occur.
