Research on Application of NC Technology in Machining Technology（2）
2 Application of CNC technology in machinery manufacturing
2.1 Automobile industry
At the same time as the rapid development of the automotive industry, people's requirements for the accuracy of automotive functions and automotive components have also increased, and the application of numerical control technology in the automotive industry has provided a powerful force for the development of the automotive industry in the direction of personalization and scale. Technical support. For example, the application of NC technology in automotive engine parts and gearbox processing.
2.2 Coal mining machinery
The promotion and application of numerical control technology in the shearer manufacturing industry not only makes the shearer manufacturing more intelligent, but also greatly promotes the improvement of the working efficiency and production quality of the shearer manufacturing. Due to the high requirements on accuracy and tolerance during the manufacture of the shearer, the operator only needs to properly adjust the distance of the slit through numerical control cutting during the actual operation, while controlling the cutting speed at Within the specified time, the purpose of promoting the effective improvement of coal mining machinery cutting efficiency can be achieved. In addition, the application of numerical control technology in the manufacture of coal mining machinery not only ensures the stability of the overall structure of the coal mining machine, but also promotes the overall improvement of the level of coal mining machinery manufacturing.
The promotion and application of numerical control technology in industrial production not only replaced the traditional manual operation. At the same time, it has ensured the orderly progress of industrial production and promoted the overall improvement of industrial production efficiency and quality. For example, industrial robots with NC technology as the core can complete industrial production activities in accordance with corresponding instructions. With the application of numerical control technology in technical processing, welding, painting and other fields, it has promoted the effective improvement of industrial production efficiency. Since the numerical control system used in industrial production is mainly completed by computer program control units, pressure sensors, vision sensors and other parts, this operation mode not only allows staff to understand and master the operating status of mechanical equipment in real time, but also In order to timely discover and feedback the problems existing in the operation of machinery and equipment, while ensuring the steady progress of process production, it has promoted the continuous improvement of product production quality.
2.4 Ship and power generation industry
As the propeller and turbine blade parts in the shipbuilding and power generation industries are not only complex in shape but also have large individual differences, in order to meet the requirements of manufacturing accuracy, machinery manufacturing companies must reasonably design the processing technology of parts and components, and at the same time adopt CNC high-speed 5-axis linkage processing. Center, heavy-duty turning and milling compound machining center and other advanced numerical control equipment, and then supplemented with computer 3D modeling, automatic programming and simulation processing materials, in order to produce precision parts for the ship and power generation industry.
2.5 Aviation sector
Aerospace equipment is mostly based on lightweight materials such as aluminum alloys and titanium alloys. Therefore, more mature cutting technology must be used in order to effectively improve the processing quality of parts on the basis of avoiding the problem of deformation of parts. For example, many precision parts in the aerospace industry production process must be processed and produced in a special way, and the high-strength materials used in them can only be processed by small cutting to ensure that the processing results are consistent with the production of parts. Quality requirements. Therefore, in order to avoid errors in the cutting process of the parts, the operators mostly adopt the method of tight integration of computer technology and numerical control technology to promote the steady improvement of machining accuracy and efficiency by controlling the machining process.
