2. Screen Operation of A985GOT
This function automatically calculates the amount of tool length compensation, by moving the
tool to the measurement point with the manual feed. There are two types of measurement
methods in manual tool length measurement I: the base point method and the measurement
value input method. The required method is selected by setting parameter "#1102 tlm".
(a) Base point method
Obtain the tool length with the tool nose placed on the measurement point.
Measurement point
(b) Measurement value input method
Actually cut the workpiece. Measure its dimensions, and obtain the tool length from the
measured values.
Work
Measurement base point
The tool length from tool length measurement I is as follows, depending on the whether
the 1st reference point coordinate values have been set.
If the 1st reference point coordinate values have been set:
Tool base position
X-axis tool
length
Z-axis tool length
If the 1st reference point coordinate values have not been set:
Z-axis tool length
X-axis tool length

2.3 (I). Tool Offset (L system)
Set the measurement point in parameter "#2015
tlml" beforehand.
The measurement base point is characteristic for
each machine (the center of the chuck face, etc.).
Measurement value
If the 1st reference point coordinate values have
been set, the tool length is the distance from the
tool's hypothetical nose to the tool base position.
If the 1st reference point coordinate values are
set to 0, the tool length is the distance from the
tool's hypothetical nose to the machine base
position.
