1.3.2 Development towards high speed and high precision This is the need to adapt to the development of machine tools in the direction of high speed and high precision.
1.3.3 Development towards Intelligentization With the continuous penetration and development of artificial intelligence in the computer field, the degree of intelligence of CNC systems will continue to increase.
(1) Applying adaptive control technology The numerical control system can detect some important information in the process and automatically adjust the relevant parameters of the system to achieve the purpose of improving the operating state of the system.
(2) Introduce the expert system to guide the processing. The experience of skilled workers and experts, the general laws and special laws of processing are stored in the system, and the expert system with artificial intelligence is established with the support of the process parameter database.
(3) Introducing the fault diagnosis expert system (4) The intelligent digital servo drive device can automatically adjust the parameters by automatically identifying the load, so that the drive system can get the best operation.
Second, the necessity of CNC machine tool transformation 2.1, the necessity of micro-view transformation From the microscopic point of view, CNC machine tools have the following outstanding advantages over traditional machine tools, and these advantages are derived from the power of the computer contained in the CNC system.
2.1.1 It is possible to machine complex parts such as curves and curved surfaces that cannot be processed by conventional machine tools.
Because the computer has superb computing power, it can instantaneously and accurately calculate the amount of motion that each axis should move instantaneously, so it can be combined into complex curves or surfaces.
2.1.2 The automation of machining can be realized, and it is flexible automation, so the efficiency can be increased by 3 to 7 times compared with the traditional machine tool.
Since the computer has the ability to remember and store, the input program can be remembered and stored, and then automatically executed in the order specified by the program to achieve automation. The CNC machine tool can realize the automation of the other workpiece processing by replacing one program, so that the single piece and the small batch production can be automated, so it is called "flexible automation".
2.1.3 The precision of the machined parts is high and the dimensional dispersion is small, which makes the assembly easy and no longer needs to be "repaired".
2.1.4 It can realize the concentration of multiple processes and reduce the frequent handling of parts between machine tools.
2.1.5 With automatic self-discipline functions such as automatic alarm, automatic monitoring and automatic compensation, it can realize long-time unattended processing.
2.1.6 Benefits derived from the above five articles.
Such as: reducing the labor intensity of workers, saving labor (one person can take care of multiple machine tools), reducing tooling, shortening the trial cycle and production cycle of new products, and responding quickly to market demand.
These superiorities are unimaginable by the predecessors and are an extremely important breakthrough. In addition, numerical control of machine tools is the basis for enterprise information transformation such as FMC (Flexible Manufacturing Unit), FMS (Flexible Manufacturing System) and CIMS (Computer Integrated Manufacturing System). CNC technology has become the core technology and basic technology of manufacturing automation.
