Based on Mastercam9.0 software,the basic idea and steps of modeling programming is introduced by taking a smal five-leaf fan as an example. The key points are the NC machining process and the parameters. The selection of location datum and tool the dislocation of the fan blade,the strength and rigidity of the fan blade are studied,and the problem of incorrect seam of the fan parts surfaces caused by the datum misalignment during the frontback machining is solved. Meanwhile,aiming at parts with complex surfaces,the technical measures based on CAD/CAM are explored and tried to improve the machining efficiency and accuracy and NC machining process.
