3.3.10 Zero approach machining
If the pitch given on the design drawing is entered in the counter, the target value from the
current position to the machining position is automatically displayed. Perform the
machining until the displayed value becomes zero. By repeating this procedure, machining
can be performed efficiently.
NOTE
Errors occurred in performing the machining are automatically corrected for the next
target value.
• Perform the machining on the Z-axis as shown below.
