Research on Simulation of Non-Orthogonal Multi-Axis NC Machining and Post-Processing Technology Based on the Coordinate Transformation

Abstract:

The technology of NC machining simulation is a reflection in virtual environment. Machining simulation may effectively reduce the invalid feeding and probability of interference or collision between cutter and fixture due to unreasonable machining parameters. Researches on machining simulation of multi-axis NC machining are complex and representativeness. This paper took a process of surface under NX CAM environment on a non-orthogonal five axis machine tool—DMU50eVolution as the object for machining simulation, by inputting the proper engagement for the cutter, using the method of coordinate transformation to create a post processor with UG post-builder and integrated into the library of post-processing. The NC codes created have been verified in the simulation system with VERICUT. And it has been shown that the preparation time of NC machining has been reduced, the efficiency of NC machining improved and the phenomenon of collision and interference effectively prevented.
