7. After looking for the reference point, re-executing Step 5 and the measure result
should be as following:
Error
Backward
Forward
Dist.
8. Setting pitch error compensation values(NC Parameters 0300 ~ 0349、0450 ~
0499、0600 ~ 0649 and 0750 ~ 0799). Assumed the LNC system pitch error
compensation value uses the relative value setting. If the laser measure software
(such as RENISHAW, HP, and est.) able to execute exchanging, there will be no
problem. But, if can only use the absolute value to indicate, the exchanging
method is as following:
The N th section relative error = the N th section absolute error – the (N-1) th section
absolute error;
The N th section compensation setting value = -ive N th section relative error.
