Which Programs Are Cnc Machining Divided Into

[Esperanza Goudy]

in traditional machining, ordinary machine tools are operated manually. When machining, shake the mechanical tool by hand to cut metal, and measure the accuracy of products with caliper and other tools by eyes. Modern industry has long used computer digitally controlled machine tools for operation. CNC machine tools can automatically process any products and parts directly according to the program compiled by technicians in advance. This is what we call "NC machining". NC machining is widely used in any field of all machining, and it is also the development trend and important and necessary technical means of mold machining. "CNC" is the abbreviation of numerical control in English. What is numerical control technology? Numerical control technology, referred to as numerical control. It is a method of using digital information to control the movement of machine tool and machining process. The machine tool that implements machining control with numerical control technology, or the machine tool equipped with numerical control system, is called numerical control (NC) machine tool. CNC system includes: CNC device, programmable controller, spindle driver and feed device CNC machine tool is a highly integrated product of machine, electricity, liquid, gas and light. To realize the control of the machine tool, it is necessary to use geometric information to describe the relative motion between the tool and the workpiece, and use process information to describe some process parameters that the machine tool must have. For example: feed speed, spindle speed, spindle forward and reverse rotation, tool change, coolant switch, etc. These information are formed into processing files in a certain format (i.e. normal NC processing programs) and stored on the information carrier (such as magnetic disk, perforated paper tape, magnetic tape, etc.), and then read in by the NC system on the machine tool (or directly input through the keyboard of the NC system, or input through communication), so as to make the machine tool act and process parts through decoding Modern CNC machine tool is a typical product of mechatronics. It is the technical basis of a new generation of production technology and computer integrated manufacturing system. The development trend of modern CNC machine tools is high-speed, high-precision, high reliability, multi-function, compound, intelligent and open structure. The main development trend is the development of intelligent full-function general numerical control device with open structure in both software and hardware. CNC technology is the basis of machining automation and the core technology of CNC machine tools. Its level is related to the national strategic position and the level of reflecting the national comprehensive strength It develops with the development of information technology, microelectronics technology, automation technology and detection technology. CNC machining center is a kind of CNC machine tool with tool magazine, which can automatically change tools and carry out a variety of machining operations on workpieces within a certain range. The characteristics of machining parts on the machining center are: after the https://asprecisionparts.com machined parts are clamped once, the NC system can control the machine tool to automatically select and replace tools according to different processes; Automatically change the spindle speed, feed rate of the machine tool, the movement track of the tool relative to the workpiece and other auxiliary functions, and continuously carry out multi process processing such as drilling, spot facing, reaming, boring, tapping, milling and so on. Because the machining center can centrally and automatically complete a variety of processes, avoid artificial operation errors, reduce the time for workpiece clamping, measurement and machine tool adjustment, as well as the time for workpiece turnover, handling and storage, and greatly improve the machining efficiency and machining accuracy, it has good economic benefits. Machining centers can be divided into vertical machining centers and horizontal machining centers according to the position of the spindle in space.
