My this graduation design including the design plan descriptions, abstract, preface, the design specification and so on many parts. Design of the main content is to our machinery processing daily processing of common workpiece take one of the typical parts of program and operating system design, from the nc machining should be obtained before the start of nc machining process analysis, to the nc tool and selection, workpiece clamping fixture with nc machining way of choice, programming of the numerical calculations, CNC programming, the numerical control turning processing, CNC milling, nc machining center programming and automatic programming technology content and so on nc machining the problems needing attention when done one explanation. One numerically-controlled machine tool we use now is Siemens system, including programming language to is Siemens system. Due to the limited ability, oneself to design o
