Control system miniaturization systematic miniaturization of numerical control benefit and bine the machine , electric device for an organic whole. Adopt the super largescale integrated ponent , multilayer printed circuit board mainly at present, adopt the threedimensional installation method , make the electronic devices and ponents must use the high density to install, narrow systematic occupying the space on a larger scale. And utilize the newtype slim display of colored liquid crystal to substitute the traditional cathode ray tube, will make the operating system of numerical control miniaturize further. So can install it on the machine tool conveniently, benefit the operation of the numerical control lathe correctly even more. 本文出自： Shigley J E. Mechanical Engineering Design. New York: McGrawHill, 1998 1 數(shù)控技術 當前世界 NC機床的研究現(xiàn)狀 世界各國對數(shù)控機床、加工中心以至 FMS、 CIMS 等各種新技術的研究與發(fā)展進程，是與世界經(jīng)濟形勢緊密相連的。 There are such research of the respect as intelligent automatic programming , intelligent manmachine interface , intelligence diagnosing , intelligent monitoring ,etc.. B、 The numerical control system melts and studies open Mainly showing in the following aspects: The development of the numerical control system is on unified operation platform, face the lathe producer and support finally, through changing, increasing or cutting out the structure target(numerical control target ), form the seriation, and can use users specially conveniently and the technical knowhow is integrated in the control system, realize the open numerical control system of different variety , different grade fast, form leading brand products with distinct distinction. System structure norm of the open numerical control system at present, norm , disposing the norm , operation platform , numerical control systematic function storehouse and numerical control systematic function software developing instrument ,etc. are the core of present research to pass through. C、 Meeting the manufacture system of the production line , demand for the information integration of the manufacturing pany workedly greatly of numerical control equipment, it is a basic unit of realizing the new manufacture mode too. Classification of the machining center （ 1） Process according to main shaft space position when it classifies to be as follows, horizontal and vertical machining center. Horizontal machining center, refer to the machining center that the axis level of the main shaft is set up . Horizontal machining center for 35 sport coordinate axis, a mon one three rectilinear motion coordinate axis and one turn the coordinate axis of sports round (turn the workingbench round), it can one is it is it finish other 4 Taxi processing besides installing surfaces and top surfaces to insert to install in work piece, most suitable for processing the case body work piece . Compared with strength type machining center it, the structure is plicated, the floor 3 space is large, quality is large, the price is high. Vertical machining center, the axis of the main shaft of the vertical machining center, in order to set up vertically, its structure is mostly the regular post type, the workingbench is suitabl
