July 2013 6.4 Axis-error compensation 655
Example The following dependencies apply for axes 2 = Y and 3 = Z:
 Ball screw pitch error in Z and Y: Z = F(Z) and Y = F(Y)
 Axis sag in Z depending on Y
 Range of traverse: Z = 800 mm, Y = 500 mm
 Datum for compensation values: Z = –200 mm, Y = –90 mm
 Desired spacing of compensation points: 7 mm
Number of compensation points:
Axis Y:
