Engraving process is characterized by multi-processing region, using small knives. Optimization mode even knives, order processing, order of layering can not only improve the processing efficiency, but also to reduce the probability of the cutting knife. These processing techniques from working practice, is the largest specialty software.

SurfMill path function characteristic features:

· Regional priorities in a hierarchical manner to improve the efficiency of processing layered;

· A high priority in a hierarchical fashion can be reduced when the thin wall machining of thin-walled deformable;

· Circumcision pass even supports polyline knife, to avoid the phenomenon of bilateral cutting knife even when;

· Remove the short path function to filter unimportant short path segment;
