These guidelines by similarity classification family return freeform piece

Freeform tool path generation is the most important part of CNC machining is also the most widely studied in-depth content. In the free-form surface multi-axis NC machining, tool path will  polycrystalline diamond  the machining precision and efficiency. Paper, based on the value of the curvature and fuzzy C partition Combination of free-form surfaces slice algorithm, using this algorithm, the nature of the surface is  abrasive grinding  several different surface patches, according to the similarity of these guidelines will go free patch ethnic classification, clustering patch group, according to the characteristics of different shapes using a suitable piece domain tool path  abrasive wheels  method to generate tool paths for processing. This paper presents a method for biasing critical areas (happened undercut region) boundary line and generate tool paths for processing, the idea is this: When a concave area on freeform minimum radius of curvature than the selected tool radius hours, it will had a partial cut.
