Normal > numerical control is to use digital information to have pilot technology to mechanical movement and working process, numerical control equipment is the new technology that is a delegate with numerical control technology permeate the Electromechanical unifinication product that fashion to what the tradition makes industry and burgeoning manufacturing industry, namely so called digitlization equips, normal >normal > its technology covers a lot of fields: Normal >normal > (1) mechanical production technology; Normal > (2) information processing technology; Normal > (3) automata technology; Normal > (4) servo drive technology; Normal > (5) sensor technology; Normal > (6) software technology. Normal >normal > machine tool of cut of numerical control of efflux of extrahigh voltage water is 20 centuries equipment of a kind of when 90 time begin to develop in China high-powered cut, the random that the principle is the data of random of cut of real time automata that uses extrahigh voltage water to pass the computer 2 dimension graph. The control of machine tool of cut of water efflux numerical control involved 2 dimension superhigh pressure 6 fields that numerical control technology uses, we emphasize particularly on under from information processing and automata two respects undertake introductory. Normal >normal > information processing is perforative numerical control technology uses medium whole process in the machine tool. It is numerical control technology is medium advocate arteries and veins, also be the the most crucial, most wonderful part in numerical control technology. In 2 dimension superhigh pressure the information processing in machine tool of cut of water efflux numerical control includes to collect, treatment, transmit 3 parts. 2 dimension superhigh pressure the flow of information processing system of machine tool of cut of water efflux numerical control is as follows (graph 1) : Normal >normal Align=center>normal >normal >normal >1. Information collects Normal >normal > is collected to graphical information, it is the crucial technology of CAD/CAM, the collection of data precision, the processing speed of data affected the efficiency of numerical control system directly. The collection of data precision is taller rate of its data processing is slower, the efficiency of numerical control system is lower. The treatment of machine tool of water efflux cut checks 2 dimension superhigh pressure any 2 dimension figures that seem any planar material, its collect precision to be in decimally hind 4 when, machine precision, control efficiency can achieve satisfactory result. In 2 dimension superhigh pressure the information in machine tool of water efflux cut collects have 4 shares: Graphical information is collected, material function and relevant treatment information are collected, state information is collected, information of real time position is collected. Normal >normal > pursues 1 showed the news that awaits treatment to resemble element figure is collected, any 2 dimension graph can be passed in AUTOCAD scale or transfer into through AUTOCAD scanning, number is illuminated after resembling a picture, depict close the face forms DXF file to undertake data is collected. Normal >normal > is the physical function that involves material, treatment in water cut treatment secondly delay time of speed, point of tangency, treatment times wait for experience to data is typed and be saved. Normal >normal > is application waiting to high pressure of pressure lead plane, voltage, electric current collect, to the machine working status monitors in real time. This share information is collected in wanting to notice to install a process in sampling circuitry only, had good screen to line means, had software filter wave to sampling data, achieved expectant data demand. Normal > to supplement each other with automata, the collection of real time information assured the athletic contrail of automata. Normal >normal > collects data except graphical information outside, the others information collects data to be able to be used use easily simply, the ACCESS database with development rapidder rate undertakes administrative. Normal >normal >2. Information machines Normal >normal MARGIN: 0cm 0cm 0pt; TEXT-INDENT: 24pt; Mso-char-indent-count: 2.

0">normal > machine tool generates module to design flow chart to be as follows (graph 2) : Normal >normal Align=center>normal >normal > information is to show through control G code module hands executive component to carry out, below the systematic platform of WINDOWS, the transmission of the file is simple and efficient, because this uses a document,exchange and network are transmitted. Normal >normal > is in 2 dimension superhigh pressure in system of automation of machine tool of cut of water efflux numerical control, be accuse a system in order to be versed in to be a center, read take and process athletic G code, to the machine tool each action part undertakes unity controlling, undertake to each parameter of athletic process real time is collected, so that have effective safe control to the machine tool. Normal >normal > principle graph pursues 3: Normal >normal Align=center>normal >normal > controls a system originally basically is in X, the electric machinery interpolation of Y axis is controlled, above all we undertake to G code data real time is handled, with serial means conducts interpolation function, issue interpolation order to athletic controller at the same time, athletic controller presses G code firm to undertake interpolation orderly, and to servo (the pace is entered) driver issues pulse signal, achieve the goal that dominates linkage of platform of X, Y. Control principle is like graph 4normal >normal Align=center>normal >normal > is in control process, the signal that can use pulse to add way controls fashion, athletic mode is positional mode, its speed-distance curve (echelon includes line of subsidiary channels in the human body through which vital energy) the 5normal >normal Align=center>normal >normal > is in on in the graph, its add decelerate the value is equal. The area of this echelon is the distance with rotational electric machinery. As a result of servo (the pace is entered) electric machinery place takes load to have certain mechanical and inertial quality, speed reachs set value impossibly immediately, so due increase decelerate level. Want to give out distance, speed and acceleration to interpolation function only actually, athletic controller includes campaign of line of subsidiary channels in the human body through which vital energy with respect to the can automatic echelon that finish, issue pulse signal to driver. Normal >normal > process designing is as follows: Normal >normal Align=center>normal >normal > is opposite X, y platform drive can use a pace to take control or servo control, the bottom will appear when the open loop system that is athletic main body into electric machinery with the pace is quickening time to grow fast in all shake, quicken a process to drop the phenomenon with serious step, if quicken time too short, quadrature of the motivation since electric machinery is insufficient, cause control systematic error is too big, affected treatment precision. Use the form a complete set of digital servo, also can put in the slight phenomenon that drop a condition, but the machine tool got good acceleration performance, pulse loss late is reduced, result of effective control precision is satisfactory. Recommend in machine tool of 2 dimension control use servo to control a system. Normal >normal > CNC Milling CNC Machining
