15. ACCURACY COMPENSATION
FUNCTION
NC FUNCTION
229
The following two functions are available:
<1> 128 straightness compensation points
<2> Interpolated straightness compensation
In conventional straightness compensation, compensation data is set for
four compensation points with parameters to obtain compensation data
along an approximate straight line connecting the four points and perform
compensation based on the data.
This function allows data for up to 128 equally spaced compensation
points to be set in the same way as for ordinary pitch error compensation.
By this function, fine compensation is also available for ”straightness
compensation.”
This function also allows up to six combinations of movement and
compensation axes for straightness compensation.
In conventional straightness compensation, for each interval between
pitch error compensation points set by parameters, the amount of all
straightness compensation at the compensation point is output and
compensation is performed.
This function equally divides the amount of compensation for each
interval between pitch error compensation points for compensation data
set using 128 straightness compensation points and outputs it as a
compensation pulse.
NOTE
To add the interpolated straightness compensation option,
the stored pitch error compensation option is also required.
