Research On NC Processing Of Complex Surface Based On CAXA

With the rapid progress of science and technology in China and the development of the manufacturing sector, the industrial production in the free-form surface machining applications are more and more widely applied. Automatic programming techniques are often used in modern production CNC machining of complex surfaces. CAXA Manufacturing Engineer is one software widely used in modern production CAD/CAM field. The paper is based on CAXA Manufacturing Engineer studying CNC machining of complex surface. The specific contents of the study are as follow:First, based on the environment of CAXA manufacturing engineers, to study complex surface roughing, finishing manufacturing methods, and coarse, finishing the choice of methods and strategies, CNC machining of complex surface simulation graphics created in CAXA the manufacturing engineers simulation module, and then the simulation processing compare and choose more suitable for complex class surface CNC machining methods.Second, based on the environment of CAXA manufacturing engineers, to study the problem of how to determine CNC cutting parameters in machining complex surfaces and other cutting parameters.Third. based on the environment of CAXA manufacturing engineers. to create postprocessor Fanuc Oi CNC machining center for complex class surface machining. and generate a new post-processing module.Forth, based on the NC simulation and actual processing under the environment of CAXA Manufacturing Engineer environment, verified that the CAXA Manufacturing Engineer environment CNC machining processing can get better quality and higher processing efficiency of the complex surface-based, to improve the traditional CNC machining of poor quality, low efficiency problem of guiding significance. CAXA Manufacturing Engineer complex surface NC machining results of this thesis, also a good reference for other similar the complex cavity mold surface machining.
