9、recent years develops very quickly , the large-scale integrated circuit makes the technology high speed sending out speed , feasible PC hardware structure composes very small. Host CPU operation speed is more and more high. The IPC386 basic frequency is 33 MHz , IPC486 , 586s basic frequency may amo
10、unt to 50 120 MHz, recently Intel gallop the processor (Pentium) , basic frequency already amount to 450 MHz. Memory capacities are also very big , volume is very small, since being that mass production , messenger cost come down , reliability improves. That in development of software aspect, OS, th
11、e Windows application, feasible PC operation are simpler and convenient especially is penetrating. From minitype, machine , the workstation build the CAD/CAM software in large amount to PC transplanting , Sanweitu display and handicraft data base on PC. The opening to the outside world plus PC , the
12、 technician who attracts a great quantity have thrown into the software exploitation , feasible PC software resource has enriched extremely. 2. Miniaturizes to satisfy the integration of machinery with electronics request With the development of microelectronics technology, the large-scale integrate
13、d circuit integration level is more and more high , volume is more and more small. The numerical control equipment factory adopt grand scale IC and adopt the surface installation handicraft (SMT), have realized three-dimensional body assembling , have equipped entire CNC with the request composing v
