Craft course is told popularly, point to whole spare parts to need the whole treatment course of the course to finished product place from semifinished product namely, the protocol of craft course is the serious content of accurate machining process, main task is to determine the amount of process and working procedure content, select a part the treatment method of each surfaces, the treatment order that decides each surfaces. CNC Machining and the main distinction that course of craft of general accuracy machine tool designs, depend on former either arrive from semifinished product the whole process of finished product, is the specific description of process of process technology of a few CNC Machining only, in Cnc accurate machining, in the whole process that CNC Machining working procedure alternates to be machined at the spare parts commonly, consequently need and other treatment technology had joined, this is the place that wants an attention in technology design. According to the characteristic of Cnc accurate machining, of CNC Machining working procedure differentiate to be able to undertake by following method commonly: 1.

With installation, treatment serves as a working procedure. This kind of method agrees with the part with treatment less content, the status that need check can be achieved after treatment is over. 2.

With same the content that machines cutting tool differentiates working procedure. Although work surface of a little accurate component can be finished in be installed, but consider the process is too long, can get some of quantity inside memory, machine tool the limitation of consecutive working hours, for instance consistent line working procedure is in a working hours paragraph inside cannot end etc, still have even if too long meeting increases the order it is as difficult as what retrieve to make mistake, because this is in Cnc nicety machining, the program of the work out cannot too long and content of each working procedure cannot too much. 3.

Divide working procedure in order to machine a division of labor. The content that needs treatment to workpiece is much, can press its structure characteristic to will machine place to be divided into a few parts, be like lumen, appearance, curved surface or plane, regard a working procedure as the treatment of each part. 4.

Differentiate with thick, finish machining working procedure, the process of accurate component treatment that a few material pledge is changeful form, need what happen to the likelihood after rough machining to be out of shape have school look. Generally speaking, every should have the process of thick, finish machining, want to part working procedure. Sequential arrangement should be mixed according to the structure of the spare parts semifinished product, and fixed position, the need of installation and clamp will consider, ordinal arrangement should press the following principle to undertake commonly. 1) go up the fixed position that the treatment of working procedure cannot affect next line working procedure and clamp, what stick general purpose machine tool machines working procedure is wear to also should consider integratedly among; 2) first treatment of the appearance after lumen; 3) with same fixed position, clamp means or with same the working procedure that machines cutting tool, best and successive treatment, in order to reduce the number changing a knife of number of heavy burden location. 4) still should abide by accurate component cutting at the same time treatment is sequential arrangement principle: First the essence after essence of life, first advocate hind second, first the aperture after the face, fiducial go ahead of the rest.
