(Common to Power Mate i–D and –H)
Usually, several tools are used for machining one workpiece. The tools
have different tool length. It is very troublesome to change the program
in accordance with the tools.
Therefore, the length of each tool used should be measured in advance.
By setting the difference between the length of the standard tool and the
length of each tool in the CNC (data display and setting : see V–11),
machining can be performed without altering the program even when the
tool is changed. This function is called tool length compensation.
