Research of the Nonlinear 3D Surface NC Machining Technology

Discuss a way of using the CAD/CAM technology to process nonlinear space surface. By analyzing the processing of nonlinear space surface, the nonlinear space surface machining process plan was determined. The fine model and program was finished by innovative using of combination modeling method in UG. Many key technical problems such as surface finish, work fixture were solved in the process of dealing with CAD/CAM of nonlinear space surface, acceptable product was made on common milling machine by using post-processing NC coding,. The process plan improved machining precision and shortened the production cycle, a good results have been obtained.
