Example
Axis 1 shows the error curve; no compensation points have been used as yet.
Reference point value is 0
Max. - travel: - 35.000 mm
Max. + travel: + 205.00 mm
Tolerance band (prescribed by machine manufacturer), e.g. 0.01 mm
Spacing between two leadscrew error compensation points, e.g. 10 mm :
235 mm traverse path/max
A- 3 compensation values
10 mm grid spacing
205 mm traverse path/max+
A+
20 compensation values
10 mm grid spacing
Total number of compensation values:
K =( A-) +( A+) + (Ref) = 3 + 20 + 1 24 compensation values
The result is NC MD 3161 = 1 (NC MD 6001), i.e. compensation point K5 is the point that
corresponds to the reference point; compensation at this point is not allowed. Compensation
point K4 is used when travel goes 10 mm in a negative direction, and K6 when travel goes
10 mm in a positive direction.
