PREPARATION BEFORE STARTING MASS PRODUCTION E-23

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.
When machining the first workpiece in test cutting, exercise due care to ensure safety.
Offset in the Z-axis direction is impossible for thread cutting or grooving.
1)
Carry out the procedure explained in
4-1 "Preparations for Checking a Program".
2)
Place the DOOR INTERLOCK key-switch in the
NORMAL
position.
3)
Close the front door.
4)
Place the PANEL key-switch in the
(ON)
position.
5)
Press the head selection switch
(head 1) or
(head 2) to select the required turret.
6)
Carry out the zero return operation.
7)
Display the OFFSET/WEAR screen.
8)
Move the cursor to the tool wear offset number of
the tool to be used using the cursor control keys.
9)
Input the tool wear offset amount.
Only when machining a workpiece for the first
time, shift the tool path by following the procedure
below.
