Programming
z The compensation mode will be automatically retreated by performing the G71, G72 or G73, if
the tool nose compensation should be used in the G71, G72 or G73 code, it can be rebuilt at the
1
st
part of the finish machining block.
4.1.7 Application
Machine a workpiece in the front tool post coordinate system as Fig. 4-13. Tool
number: T0101, tool nose radius R=2, imaginary tool nose number T=3.

Fig. 4-13
For toolsetting in Offset Cancel mode, after toolsetting, Z axis offsets one tool nose
radius and its direction is relative to that of imaginary tool nose and toolsetting point,
otherwise the system excessively cuts tool nose radius when it starts to cut.
Set the tool nose radius R and imaginary tool nose direction in “
TOOL OFFSET&WEAR”
window as following:
