Classification of CNC machining occupational levels

1. Blue-collar layer: namely, CNC machining operation technicians, proficient in invar machining and CNC machining process knowledge, proficient in the operation and manual programming of CNC machine tools (attribute: automatic machine tool), and understand the simplicity of automatic programming and CNC machine tool (attribute: automatic machine tool) Maintenance and repair, this kind of personnel has a large market demand, and is suitable as a CNC machine tool (attribute: automated machine tool) operator in the workshop, but due to their single knowledge, their salary will not be much higher.

2. Gray-collar layer: First, CNC machining programmer: master the knowledge of CNC machining technology and the operation of CNC machine tools (attributes: automated machine tools), and be familiar with the design and manufacturing expertise of complex molds (title: mother of industry). Three-dimensional CAD/CAM software, such as UG, GOOGLE PRO/E, etc.; proficient in CNC automatic programming and manual programming technology. CNC machining is a process method for parts machining on CNC machine tools. The process rules of CNC machine tool machining and traditional machine tool machining are generally consistent, but significant changes have also taken place. A machining method that uses digital information to control the displacement of parts and tools. It is an effective way to solve the problems of variable parts, small batches, complex shapes, and high precision, and to achieve high-efficiency and automated machining. In the numerical control machining, the control system issues instructions to make the tool perform various motions that meet the requirements. The shape and size of the workpiece are expressed in numbers and letters in the form of technical requirements and machining requirements. It generally refers to the process of invar machining parts on CNC machine tools. In order to improve production automation, shorten programming time and reduce CNC machining costs, a series of advanced CNC machining technologies have been developed and used in the aerospace industry. This kind of personnel is in high demand, especially in the mold (title: mother of industry) industry is very popular, and the salary is also high. Second, maintenance and repair personnel of CNC machine tools (attributes: automated machine tools): master the mechanical structure and electromechanical joint adjustment of CNC machine tools, master the operation and programming of CNC machine tools, and be familiar with the characteristics of various CNC systems, software and hardware structures, PLCs and parameters (parameter) settings. Proficient in the mechanical and electrical debugging and maintenance of CNC machine tools. The demand for such personnel is relatively small, but it is very difficult to train such personnel and requires a large amount of practical experience (experience) accumulation, which is currently very scarce, and their remuneration is also high.

3. Gold-collar layer: belongs to CNC machining generalists, possesses and is proficient in CNC machining operation technicians, CNC programmers, and CNC maintenance and repair personnel with comprehensive knowledge, and has accumulated a lot of practical experience (experience) in actual work. Very wide. CNC machining CNC is also called computer gong, CNCCH or numerical control machine tool. It is actually a kind of name in Hong Kong, which greatly reduces the number of tooling. CNC machining machining parts with complex shapes does not require complex tooling. CNC machining is a new type of invar machining technology. It is to compile the machining program, that is, to convert the original manual work to computer programming. If you want to change the shape and size of the part, you only need to modify the part machining program, which is suitable for new product development and modification. Proficient in the mechanical structure design of CNC machine tools (attribute: automated machine tool) and electrical design of CNC system, master the electromechanical joint debugging of CNC machine tools (attribute: automated machine tool). Able to complete the selection of the numerical control system, the design, installation, debugging and maintenance of the electrical system of the numerical control machine tool. Can independently complete the CNC transformation of machine tools. They are sought-after talents of enterprises (especially private enterprises), and their remuneration is very high.
