Tool-path Programming Based on Reverse Engineering in NC Machining;

Tool-Path Programming Research Based on UG Redevelopment in NC Machining;

The characteristic of current cutter path generation method is discussed.

According to the given geometrical solid and the specification of NC machining parameters, the solid finish NC machining algorithm can automatically generate the cutter path code for the finish NC machining.

Tool path generation based on point cloud directly;

Automatic Generating Method of Tool Path for NC Engraving;

Research on Optimization Strategies of High-speed Machining Tool Path;

In automatic programming, according to the shape features and machining requirements of some parts, the simple frame model can be used directly to generate the required toolpath after appropriate disposition.

Because of selecting geometry features repeatedly, random programming and bad integration during NC programming for the aircraft frame part, the technology of rapid programming based on feature is studied to implement auto-generation of the toolpath for typical machining features of aircraft frame part.
