Introduction
In recent years, the machinery manufacturing industry is facing a rapid change in the scale and form of production, the production process from large batch production to small and medium batches or single piece production; product requirements from a single product type tends to a wide variety of products, production batch of different large number of products to adapt to the new era of diversified and rich market demand.
At present, the research literature and writings on the application of the branch of computer numerical control (CNC) research field are declining, and there is a certain degree of summary for the application of various aspects of CNC.Since the mid-1980s, the high speed development of CNC system technology, the high-speed CNC machine tools are included in the pioneering development goals of countries, mainly in the spindle speed, table movement speed, tool change speed of high-speed.Into the 21st century, CNC machine tool development goals shifted from "speed" to "precision", such as with the

Mechanical manufacturing industry on the requirements of mechatronics CNC technology
Machinery manufacturing industry for the production and processing of products with high precision and high efficiency and stability of the basic requirements, CNC equipment is the modernization process to achieve flexible automation of important equipment, in various industries have been increasingly widely used.Therefore, in order to adapt to the production needs of the machinery manufacturing industry, CNC equipment generally requires the following characteristics: adaptable, capable of complex movement, high precision, stable quality, high productivity, convenient production management.
In the CNC system, most of them do not have the exact grade boundary.For reference, evaluation indicators include: CPU performance, resolution, feed speed, the number of linked axes, servo level, communication functions, and the human-machine interface.CNC machine feed speed can reach 10 ~ 0m/min.The pulse equivalent and CNC machine processing accuracy are inversely proportional to the pulse equivalent of ordinary CNC machine tools, which is typically 0.001 mm, and precision or ultraprecision CNC machine tools, which is typically 0.0001 mm.
Actual pulse equivalent = transmission ratio * screw pitch / motor pulse per revolution The use of digital information to control the machine tool, that is, the use of coded digital information to enter the tool trajectory into the program operation, into the relative motion of the lathe workpiece, and the tool to process the required workpiece of a CNC lathe, is referred to as CNC machine tool.The basic requirements of the machine manufacturing industry for CNC lathes are based on their main performance indicators, such as the main specifications of the CNC lathe's size, the performance of the spindle system, the performance of the feed system, and the quality of the tool system.Among them, the rigidity and vibration resistance of the spindle system, the speed range, and rotary accuracy corresponding to the motor drive method used, all determine whether the tool has a constant cutting speed.The feed system plays a key machining role, and its feed speed range, air travel speed range, motion resolution, positioning accuracy, and pitch range are all critical to machining efficiency, product quality, and equipment life.
CNC machine tool processing, or due to uneven machining allowance, or due to the unstable movement of the transmission parts and other factors, so that the spindle in the process of rotation vibration, will make the accuracy of the workpiece being machined decline, and even damage the CNC equipment.This requires that the main drive and spindle components should have good vibration resistance and thermal stability.
In addition to the accuracy requirements to be made at the beginning of production, CNC machine tools are often required to predict the size of the problems encountered in the production process, thus ensuring the maximum suppression of all types of errors.First of all, the positioning processing errors generated by the deformation of the machine bed, base, column, and other support parts depend on their structural stiffness.Therefore, the machinery manufacturing industry in general should reasonably select the structural form of the support parts, a reasonable structural layout, the use of measures to compensate for deformation and the reasonable choice of component materials.Second, the CNC machine tool processing environment is harsh.Under the influence of internal and external heat sources, equipment components may be damaged to varying degrees, the relative movement between the tool and the machined workpiece accuracy will also be greatly reduced, so CNC machine tools are required to reduce the heat generated in the machine, improve heat dissipation and insulation conditions, reasonable design of the machine structure and layout, or according to the laws of thermal deformation, the establishment of a mathematical model of thermal deformation, thermal deformation compensation.. Then it is to reduce the friction of the mechanism's motion, in order to improve transmission accuracy, under the index of stable operation, to achieve safe operation and have a beautiful shape [4].

Analysis of the specific application of mechatronics numerical control technology
Mechatronics CNC technology has the advantages of strong adaptability, solid quality, high production efficiency, strong second creation performance, etc.According to the different control objects, there are various categories of CNC equipment.The main applications of CNC technology have many different classifications in the field of machinery [5].

CNC machine tool processing
According to the servo control system of CNC machine tools, motion control trajectory, manufacturing methods, can control the linkage of the coordinate axes, functional level in turn can be divided into several categories [6].The servo control system of CNC equipment is generally based on a closed-loop CNC system.The position detection device of this type of system is installed on the machine table, measuring the relative position of the set table and establish the coordinate system, and CNC device to compare the commanded position, with the difference for control.Such CNC technology can detect the actual position, eliminate errors and gaps caused by the transmission link, and improve production accuracy.Among similar key classifications, CNC system is also one of the ways to distinguish CNC machine tools, such as special CNC system and general-purpose CNC system, the former has a reasonable layout, strong specialization, but the hardware cannot be replaced between them, the generality is poor; the latter has PC as the CNC device support platform, is easy to achieve updates, has anti-interference ability, and the development situation is relatively convenient [7].

Monitoring technology applications
The basic requirement of the manufacturing workshop for monitoring CNC technology lies in real-time monitoring.Workshop data information is relatively scattered, the system needs to solve the problem of compatibility of different equipment communication systems, and the unified management of information is the primary problem that needs to be solved at the decision-making level.In addition to timely monitoring of workers' processing environment, predicting accidents that occur during construction for easy resolution, and providing workers with a better quality construction environment, remote real-time unified monitoring of machine tools and data analysis also ensure the accuracy and timeliness of data [8].Data sampling of the processing location and transporting it to the client for processing display can effectively use CNC technology to improve production efficiency and have the opportunity to reduce the production process manufacturing links, so that the expected processing products become more real-time viewable and controllable.

Aerospace manufacturing field
Aerospace manufacturing products, compared to traditional industrial processing products, have fewer batches, high precision, high complexity, and other characteristics.This means that the production is difficult, can not be unified standard large batch production, so CNC technology for the requirements of great flexibility of the aviation business has a certain solution ability.Under the high requirements, CNC technology can use a computer network system to establish a dedicated network.For the malleable new generation of CNC machines, they can ensure that the quality of the product is constantly and repeatedly checked during the machining of the workpiece and even compensate or correct abnormal problems, and the advantage of high feedback makes it possible to bring a stable output advantage to the product.Build for precision requirements are extremely high, so the CNC machine itself for processing tools, such as the table or tool self-maintenance, is also an important part of the repair, not only to reduce the waste of materials, but also to reduce the burden of manual maintenance and the cost of various costs, but also to reduce the safety risks of maintenance in a harsh construction environment [9].

CNC technology is a new manufacturing technology developed on the basis of microelectronics, computers, automatic control, automatic detection, and precision machinery manufacturing technologies.At present, it is developing in the direction of high speed, high precision, and high reliability.
CNC technology has increased the feasibility of some industrial manufacturing, CNC equipment can provide operators in industrial manufacturing in the industrial production of safety forecasts, through the production and manufacturing environment and the operation of the process of internal possible hidden dangers for the management of the staff to further facilitate mechanical processing to provide good access; CNC system developed the programmable interface of the machine tool, and replace the huge relay with software Sequential logic, reducing the workload of the programmer, and its system can provide a more intuitive and clear inspection environment.CNC technology not only adds a certain degree of help to the feasibility of construction, but also enhances the comprehensive level of mechanical control increases the level of stable play.Anti-interference performance makes it in the industrial manufacturing to improve the product output rate, and it also provides convenience for the comprehensive management of monitoring and processing, making unmanned processing possible, reducing the corresponding industrial labor costs, adding to the future of machinery development [10].
