5 Setting a Tool and a Workpiece
Manual tool length measurement II
By using a device having a touch probe, the tool compensation amount can be calculated just by contacting the tool nose
against the touch probe with manual feed.
Set the measurement basic position (sensor position) with the parameter "#2015 tlml-" and "#2016 tlml+" when using the
main spindle side, "#2097 tlml-" and "#2098 tlml+" when using the sub spindle side.

When measured at the main spindle side:
Xm: - sensor machine coordinate position X axis (position measured by moving in - direction) -> #2015 tlml- X axis
Zm: - sensor machine coordinate position Z axis (position measured by moving in - direction) -> #2015 tlml- Z axis
Xp: + sensor machine coordinate position X axis (position measured by moving in + direction) -> #2016 tlml+ X axis
Zp: + sensor machine coordinate position Z axis (position measured by moving in + direction) -> #2016 tlml+ Z axis
When measured at the sub spindle side:
Xm: - sensor machine coordinate position X axis (position measured by moving in - direction) -> #2097 tlml2- X axis
Zm: - sensor machine coordinate position Z axis (position measured by moving in - direction) -> #2097 tlml2- Z axis
Xp: + sensor machine coordinate position X axis (position measured by moving in + direction) -> #2098 tlml2+ X axis
Zp: + sensor machine coordinate position Z axis (position measured by moving in + direction) -> #2098 tlml2+ Z axis
Tool compensation amount = Machine coordinate position (machine coordinate position at the time of skip input) - Mea-
surement basic position (sensor position)
The expression above is used for automatic calculation in Manual tool length measurement II.
When the tool touches the touch probe while measurement switch is ON, the calculation result is set in the tool data of the
compensation No. specified with "Tool No. (Tool length measurement 2)" (PLC device), and the wear data of the compen-
sation No. set in "Wear compensation No. (Tool presetter)" (PLC device) is cleared.
