2 - 14 NJ/NY-series G code Instructions Reference Manual (O031)
Use the skip function and measure the wear volume of tool length. In this example, the tool touches the
sensor and skip signal is input while it moves toward the cutting surface. The stop position is captured
using the skip signal, and notified to the sequence control program as an argument of M code output.
Based on the captured position, calculate the wear volume of tool length in the sequence control pro-
gram. For the procedure for setting the wear volume of tool length that was calculated, refer to the
How
to Enable Tool Replacement in the NJ/NY-series NC Integrated Controller User’s Manual (Cat. No.
O030).
Use of M101 for transferring the captured data to the sequence control program is an example. When
using this command, refer to the instruction manual provided by the machine tool manufacturer.
