Programming example

Two-point measurement, outside and inside
An outside diameter with tool T8, D1 and an inside diameter with tool T9, D1 has been
machines on a workpiece. The set diameters have the dimensions shown in the figure.
If the absolute value of the difference determined is >0.002 mm, 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. 0.5 mm. Max. 0.04 mm is permissible. To obtain a minimum
measuring path of 0.5 mm, the measuring path is programmed as _FA= 0.5+0.5=1 mm
(max. total measuring path = 2 mm).
