5.3.2 Tool Measurement (L System)

Manual tool length measurement I or II can be performed on the tool registration (T-reg) screen of the setup (Setup) screen.
Either one is selected depending on the setting of measurement switch and operation mode.
Manual numerical value command can be executed when manual numerical value command window is displayed by input-
ting an address key such as MST, etc.
There are two types of key operation for Manual tool length measurement I: normal operation mode and simple operation
mode, which can be selected by the parameter "#8957 T meas (L)-Simple".
#8957 Manual tool length measurement I operation mode
0 Normal operation mode
1 Simple operation mode
Manual tool length measurement I (when measurement switch is ON)
This is the function to calculate the tool length compensation amount automatically by moving the tool to the measurement
point with manual feed.
Move the tool to the face or side, and calculate the tool compensation amount from the measurement position (machine
position) and program zero point offset (L).

The tool length is automatically calculated by the following formula:
Tool length = Measurement position - Program zero point offset (L)
Note
(1) For the program zero point offset (L), set the diameter value for a diameter axis (#1019 dia = 1) or the radius value for
a radius axis (#1019 dia = 0).
