Planar slot cam machining process design and programming Abstract: machinery manufacturing processing technology in human production practice and development.Machinery manufacturing processing machinery manufacturing industry is the foundation, is the production of high-tech products to protect.Left it unable to develop advanced products and ensure the quality of products, reduce the cost and shorten the production cycle, improve productivity, therefore, a good processing technology and program, deciding an enterprise economic benefits.

This paper mainly introduces the mechanical product plane groove cam machining process design and program editing, including: parts of the plan, parts of the process analysis, design process, selection of machine tools and processing equipment, determine the cutting quantity, determine the process and take the knife line, parts machining process card, NC machining process card, NC machining tool cards, process design, preparation process, and the preparation of documents processing procedure.

In addition to the introduction of planar parts processing technology design and machining process design, also introduced the machinery manufacturing machining process and program editing in machinery manufacturing industry and the role of mechanical manufacturing technology current situation and development. In the design of the school on the selection of location datum, the workpiece positioning method of box part structure, process analysis.

At the same time in the graduation design also applies to MAutoCAD, UG drawing functions and mstercam simulation processing and automatic program editing function.

This graduate design reflects the machinery manufacturing processing technology and fixture design of the purpose is: to ensure and improve product quality。to raise labor productivity。to raise economic benefits. Key words: numerical control technology in mechanical manufacturing process analysis of machine processing scheme of program editing.
