8 TO FINISH A WORKPIECE WITHIN THE SPECIFIED TOLERANCE
WITH THE TOOL WEAR OFFSET FUNCTION (TEST CUTTING)
When the cutting tool moves along the programmed tool path, there may be cases where the
workpiece cannot be finished within the required accuracy due to cutting resistance, tool
deflection, tool nose R, or tool tip wear.
In this case, the programmed path should be shifted in parallel to the X- and Z-axes after
completing the test cutting so that the workpiece can be finished within the specified tolerance.
Input the amount by which the tool path should be shifted as the tool wear offset data.
CAUTION
Offset in the Z-axis direction is impossible for thread cutting or grooving.
