1-point measurement at outside diameter, measuring with reversal
An outside diameter with tool T7, D1 has been machined on a workpiece. The set diameter
has the dimension shown in the figure.
This outside diameter is to be measured with reversal. The spindle is SPOS-capable.
If the absolute value of the difference determined is >0.002, the length (in measuring axis
_MA) of the tool is to be automatically offset in the wear.
The maximum permissible deviation is taken as max. 1 mm. Max. 0.4 mm is permissible.
To obtain a minimum measuring path of 1 mm, the measuring path is programmed as
_FA=1+1=2 mm (max. total measuring path = 4 mm).
The offset is not to consider an empirical value and no mean value is calculated or used.
Clamping for workpiece:
Zero offset, with settable ZO G54: NVz
Workpiece probe 1, used as tool T9, D1, is to be used.
The probe is already calibrated. Arrays for workpiece probe 1: _WP[0, ...]
The following is entered under T9, D1 in the tool offset memory:
Tool type (DP1):
Cutting edge position (DP2):
Length 1 - geometry (DP3):
Length 2 - geometry (DP4):
