"15 " during, many war industry enterprises introduced machine tools of a large number of high-grade numerical control. How to raise its to machine efficiency and utilization rate to become day to show outstanding issue. For this, national defence division is versed in appoint efficient cutting engineering technology was arranged in plan of scientific research of national defence foundation special, begin a technology to tackle key problem with demonstrative application, begin in entire industry " industry of national defence science and technology project of synergism of machine tool of 1000 numerical control " , popularize application to advanced numerical control is emulated and digitlize compositive production technology in the round, obtain apparent effect, the attention that is led by the State Council, become a state the serious content of the energy-saving job that decrease a platoon. Efficiency of numerical control treatment is low the bottleneck that becomes promotion army to taste development productivityBecause war industry product is high quality,wait for special requirement with high accuracy, numerical control machine tool becomes war industry enterprise to produce the necessary tool that makes crucial component and measure, the effect that cannot replace is having in product development production. Because engineering technology is backward, software of fundamental technology, form a complete set and management did not catch up with accordingly, the numerical control equipment of partial unit uses efficiency not tall, check statistic according to preliminary attune, it is the 1/4 left and right sides of the developed country only, restricted the development of weaponry of new and high technology and batch production badly. Some industry leaders have feeling ground greatly to say, "War industry goods lot is produced, into in machine add, be defeated also machine add. " efficiency of numerical control treatment is low one of main bottleneck that already became promotion to war industry product is developed and approve productivity. The main reason that produces above problem has two: It is compositive production technology application is more backward. Electron of credit of platform of numerical control job shops changes basic already implementation, but computer of workshop of most numerical control assists production to plan management (planning of order processing, production, exercise attempers, control of quality of task allocation, working procedure, spot produces information report of feedback, statistic) run a system with production resource (personnel, equipment, cutting tool, clamping apparatus, level of whole of CAD/CAM/CAPP compositive application is not high still, production prepares time to grow too; 2 it is the support of technical data library with unified lack, numerical control treatment is optimized and emulate ability to compare weakness. Process designing of company numerical control is to use commercial CAD/CAM software system to make NC system automatically commonly, but craft him need weaves, the standard standard that unites because of lack and optimize a database (wait like database of project of cutting parameter library) prop up, cause numerical control process designing a craft member an appearance, similar spare parts many appearance, a lot of craft are unreasonable, factitious element impact is big, NC program moving efficiency is low, restricted the development of numerical control technology greatly.
