Abstract: With the continuous development of science and technology, numerical control technology in the enterprise play a more and more important role. This design through the analysis of process characteristics, the NC machining process, choose the correct processing methods, design the reasonable process, give full play to the characteristics of NC machining of high quality, high efficiency and low cost. The design specification of CNC lathe turning shaft parts as an example, according to the material, the shape of theworkpiece contour machining, the machining precision of the machine tool suitable for processing scheme, and determine the parts processing order, the tools used in the process, fixture and cutting machining parts,written procedures. According to the requirements of the specificationwill be processed out parts, and parts of the self inspection data analysis, note in the processing process should pay attention to the matters.
In this paper, the processing technology of milling parts is described. Three-dimensional map is drawn by Master CAM X5. Then, the surface milling surface is processedwith an ?50mm milling cutter,with a 10-stand milling cutter for groping processing convex table contour, groping processing, and finallywith 11.8 and 12 reamers for circular hole processing, and the procedure is finally derived。
Keywords: Process analysis, process flow, three-dimensional modeling, automatic programming
