原文： The digital control process technology is summarized 1. digital control programming reaches such development The digital control programming is the segment that be able to obviously bring into play the beneficial result in at the moment CAD/CAPP/CAMs system the most most , such is living to achieve to design the process automation and raise process accuracy and processes the quality and cuts down the product development cycle and so on the respect is brining into play the significant action . Being living possess the greats quantity applications such as aviation industry and auto industry and so on territorys . Since giving birth to the intense demand of practice , wide-ranging research has wholly been carried on to the digital control programming technique in the home and abroad , and acquires the plentiful and substantial fruit . The next reaches such to the digital control programming and develops to act as some to introduce . 1.1 basic concept of digital control programming The digital control programming is through the spare parts drawings up the full process that obtains the digital control processing program . Its main mission is that the sword spot Cutterlocationpoint abbreviate CLs spot in the sword is processed away in the calculation . The point of intersection that sword the spot was oridinarily get to the cutting tool axial line against the cutting tool face still will be give out the sword shaft vector in much processs 1.2 digital control programming technique development survey MIT designed one kind of special language that is used in the inflexible spare parts digital control processing program establishments to the program problem in order to resolve in the digital control process , and is called APT AutomaticallyProgrammedTool in the 50s . Well-developed editions such as after APT time and again develops , takeed shape such as APTII and APTIII the stereoscopic cutting action is employd and APT the algorithm improves , add
