Abstract
In recentyears, our country attaches importance to numerical control technology, numerical control technology has been developing, because of high efficiency, high precision, high quality so that NC machining technology is more and morewidely used.
The task of this design is to design the machining process and program simulation of the coil core parts. The two-dimensional graphics of the parts are drawn by CAD software, and then the three-dimensional drawings are drawn by Mastercam software. Then the structure, precision and technical requirements of the parts are analyzed. Design NC process scheme for machining parts, select blank material and size, tool for machining, machining machine, and reasonable cutting parameters, etc. Select the best machining process plan, and then use the CAM module in Mastercam to compile the NC machining program of the parts, and complete the design.
Keywords: milling; CAD/CAM; NC machining process; programming
