Research and development visual simulation of NC machining system

Firstly, this paper summarizes research status and existing problems in NC machining simulation. Then, the paper discusses a visual simulation of NC machining system combining geometric simulation and physical simulation. The paper explains in details the method of NC program disposed by a computer automatically, the technique modeling of visual simulation environment of NC machining and the principle of NC machining process visual simulation. The mathematic model of surface roughness is built to predicate a machined surface roughness.
