Example 1 The position of the tip of the reference tool when the tool is at the machine zero point is used
as the measurement reference position. The distance between the position of the tip of the
tool to be measured and the reference position can be set as the tool geometry compensa-
tion.

Xp : Measurement reference distance to the sensing surface in the +X feed direction (parameter
setting)
Xm : Measurement reference distance to the sensing surface in the –X feed direction (parameter
setting)
Zp: Measurement reference distance to the sensing surface in the +Z feed direction (parameter
setting)
Zm : Measurement reference distance to the sensing surface in the –Z feed direction (parameter
setting)
Xt : Machine coordinates along the X–axis when the tool to be measured contacts the sensing
surface in the –X feed direction
Zt: Machine coordinates along the Z–axis when the tool to be measured contacts the sensing
surface in the –Z feed direction
GOFSx : Tool geometry compensation along the X–axis (GOFSx = Xt – Xm)
GOFSz : Tool geometry compensation along the Z–axis (GOFSz = Zt – Zm)
