Discussion about Object Profile Cognitive Based on Biological Characteristics;

A new tool path generation algorithm was presented to eliminate interferences,when nesting convex mold and concave die were machined with tool paths calculated by offsetting the 2D profile directly.

In this paper,bottom surface profile algorithm without compensation is deduced firstly based on laminated machining approach and uniform wear method.
