What is numerical control technology?
Traditional mechanical processing is carried out manually using ordinary machine tools. During processing, the mechanical cutting tools are shaken by hand to cut metal, and the accuracy of the product is measured using tools such as calipers with the eyes. Modern industry has long used computersdigitizationThe controlled machine tool is operating,numerical control machineIt is possible to automatically process any product and component directly according to the program pre programmed by the technical personnel. This is what we call 'CNC machining'. Numerical control machining is widely used in any field of mechanical processing, and is also the development trend and important and necessary technical means of mold processing. What is?Numerical Control Technology？
Computer digital control, abbreviated as numerical control. It is a method of using digital information to control the motion and processing of machine tools. useNumerical Control TechnologyA machine tool that implements machining control, or is equipped with a numerical control system, is called a numerical control (NC) machine tool. The numerical control system includes:Numerical Control DeviceProgrammable controller, spindleDriverAnd the feeding device and other parts Numerical control machine tools are highly integrated products of machinery, electronics, hydraulics, pneumatics, and optics. To achieve control of machine tools, it is necessary to use geometric information to describe the relative motion between the tool and the workpiece, as well as process information to describe some of the necessary process parameters for machine tool machining. For example: feed rate, spindle speed, spindle forward and reverse rotation, tool changeCooling fluidThe switch, etc. These pieces of information are formatted into processing files (commonly known as CNC machining programs) and stored on information carriers (such asdiskThePerforated paper tapeThemagnetic tapeThen, it is read in by the numerical control system on the machine tool (either directly through the keyboard of the numerical control system or through communication), and decoded to make the machine tool move and process the parts Modern CNC machine tools are typical products of mechatronics integration and represent the new generation of production technologyComputer Integrated Manufacturing SystemThe technical foundation of waiting.
modernnumerical control machineThe development trend is towards high-speed, high-precision, high reliability, multifunctionality, composite, intelligent, and open structure. The main development trend is the research and development of intelligent, fully functional, and universal software and hardware with open structuresNumerical Control Device.Numerical Control TechnologyIt is the foundation of mechanical processing automation and the core technology of CNC machine tools. Its level is related to the national strategic position and reflects the comprehensive strength of the country It has developed with the advancement of information technology, microelectronics technology, automation technology, and detection technology. numerical controlmachining center It is a CNC machine tool with a tool magazine that can automatically replace cutting tools and perform various machining operations on workpieces within a certain range. The characteristics of machining parts on a machining center are: after being clamped once, the CNC system can control the machine tool to automatically select and replace cutting tools according to different processes; Automatic changeMachine tool spindleThe speed, feed rate, and relative motion trajectory of the tool to the workpiece, as well as other auxiliary functions, continuously perform multiple processes such as drilling, countersunking, reaming, boring, threading, milling, etc. on each machining surface of the workpiece automatically. Due to the centralized and automatic completion of multiple processes by machining centers, human operational errors are avoided, and the time for workpiece clamping, measurement, and machine tool adjustment, as well as workpiece turnover, handling, and storage, are reduced. This greatly improves machining efficiency and precision, thus having good economic benefits. Machining centers can be classified according to the position of the spindle in spaceVertical machining centerCompared to horizontal machining centers.
