This option is recommended if the control has to transform many straight lines calculated by a CAM system into a smooth curve.
This option is recommended for the NCU 730 as well as for the standard controller. For machines with standard controller (NCU 720) the data compressor software is precondition for good result if one works with CAM programmes.
The data compressor combines a sequence of G1 blocks in accordance to an adjustable range of tolerance and converts this contour section into a spline. The smooth curves lead to a more steady movement without acceleration jumps and therefore to a better surface and shorter cycle times.
