Measuring variants
3.3 Measure workpiece (milling)
Note
The four measuring points or the measuring path DFA must be selected so that contour within
the total path: 2 · DFA [in mm] is reached. Otherwise, no measurement will be able to be made.
Internally in the cycle, a minimum value of 20 mm for the measurement distance DFA is
generated.
Measuring variant, turning on a milling machine (only 840D sl)
