1、High speed
With the rapid development of automotive, national defense, aviation, aerospace and other industries, as well as the application of new materials such as aluminum alloys, the high-speed requirements for CNC machine tool processing is increasingly high.
(1) spindle speed: machine tools using electric spindle (built-in spindle motor), the maximum spindle speed of 200000r/min.
(2) feed speed: in the resolution of 0.01μm, the machine tool can obtain a maximum feed speed of 240m/min, which can be accurate processing of complex surfaces.
(3) computing speed: the rapid development of the microprocessor for the CNC system to high-speed, high-precision direction, the result of the CPU has developed to 32-bit and 64-bit CNC system, the frequency increased to several hundred megahertz, thousands of megahertz. Due to the substantial increase in computing speed, when the resolution of 0.1μm, 0.01μm can still obtain up to 24 ~ 240m/min feed rate.
(4) tool change speed: the current advanced foreign exchange time has generally been about 1s, high has reached 0.5s. German Chiron company will be designed as a basket type spindle, the spindle as the axis, the tool is arranged in the circumference, the tool change time is only 0.9s.

2、High precision
CNC machine tool accuracy requirements are now not limited to static geometric accuracy, machine tool motion accuracy, thermal deformation, vibration monitoring and compensation, etc. are increasingly important.
(1) improve CNC machining accuracy: the use of high-speed interpolation technology to achieve continuous feeding of tiny program segments so that the CNC unit refinement, and the use of high-resolution position detection device to improve the position detection accuracy (Japan has developed with 106 pulses / revolution of the built-in position detector AC servo motor, its position detection accuracy can reach 0.01μm / pulse), position servo system using feed-forward control and nonlinear control and other methods.
(2) Adopting error compensation techniques: backlash compensation, pitch error compensation, tool error compensation and other techniques are used to compensate for the thermal deformation error and spatial error of the equipment. The research results show that the application of comprehensive error compensation technology can reduce 60% to 80% of machining errors.
(3) Check and improve the accuracy of machining center's motion trajectory by using grid. The machining accuracy of the machine tool is predicted through simulation to ensure its positioning accuracy and repeat positioning accuracy. Thus, its performance is stable over time, and can complete a variety of machining tasks under different working conditions to ensure the quality of parts processing.

3, functional compounding
Composite machine tool is the meaning of a machine tool to achieve or as far as possible to complete the processing of multiple elements from the blank to the finished product. Its structural features can be divided into two categories: process-composite and process-composite. Process composite machine tools such as boring, milling, drilling composite - machining center, turning and milling hybrid - turning center, milling, boring, drilling, turning composite - machining center, etc.; process composite machine tools such as multi-surface multi-axis joint processing of composite machine tools and dual-spindle turning centers. The use of composite machine tools for processing, reducing the workpiece loading and unloading, changing, adjusting the tool extra time. And the errors generated in the intermediate process to improve the machining accuracy of the parts, shorten the manufacturing cycle of the product, improve the production efficiency and the manufacturer's market responsiveness, as opposed to the traditional process of piecemeal production methods have obvious advantages.
4、Intelligent control.
In order to meet the development needs of manufacturing production flexibility and automation, the degree of intelligence of CNC machine tools is constantly improving. It is clearly reflected in the following aspects.
(1) process adaptive control technology: by monitoring the machining process cutting force, spindle and feed motor power, current, voltage and other information, using traditional or modern algorithms for identification, to determine the force, wear, breakage state of the tool, as well as the stability of the machine tool processing state, and according to these states real-time adjustment of processing parameters (spindle speed, feed rate) and processing instructions, so that the equipment in improving machining accuracy, reduce surface roughness and improve the safety of equipment operation.
(2) Intelligent fault self-diagnosis and self-repair technology: Based on the existing fault information, modern intelligent methods are applied to achieve fast and accurate fault location.
(3) intelligent fault playback and fault simulation technology: the ability to complete the record of various information in the system, a variety of errors and accidents occurring in CNC machine tools to play back and simulation, determine the cause of the error, find ways to solve the problem and accumulate production experience.
(4) intelligent AC servo drive: can automatically identify the load and adjust the parameters of the intelligent servo system, including intelligent spindle AC drive and intelligent feed servo device. This drive can automatically identify the rotational inertia of the motor and load, automatically optimize and adjust the parameters of the control system, so that the drive system to obtain the best operating conditions.
(5) intelligent 4M CNC system: in the manufacturing process, processing, testing integration is to achieve rapid manufacturing, rapid detection, rapid response in a practical way, the measurement (Measurement), modeling (Modelling), processing (Manufacturing), machine operation (Manipulator) four (i.e. 4M) integrated in a system The 4Ms are used to share information and facilitate the integration of measurement, modeling, machining, clamping, and operation.
