What are the characteristics of NC machining technology?
- First of all, let’s know what CNC is, that is, computer data control, that is, numerical control machining. Numerical control machining is a high precision advanced machining technology in modern machinery manufacturing. Numerical control machining technology can effectively solve the mold and other complex, precise, changeable processing problems, fully meet the needs of modern production. In order to accelerate the economic development of our country and improve the ability of independent innovation, the numerical control machining is an indispensable technology in modern production.
- Numerical control machining process is a kind of machining, also abide by the cutting law of machining, and ordinary machine tools are roughly the same. Due to the application of computer control technology in automatic machining, it has the characteristics of high efficiency and high precision. Processing technology has its unique, complex technology, carefully arranged technology.
- Nc machining technology includes the selection of cutting tool, the determination of cutting parameters and the design of feed process route. Nc machining technology is the foundation and core of NC programming. Only reasonable technology can produce high quality NC program. The standard of measuring the quality of NC program is: short processing time, small cutting tool loss, good workpiece effect.
- Numerical control machining process is a part of the overall machining process of the workpiece, or even a process. Only with other processes, to meet the requirements of machine or mold assembly, so as to process qualified parts.
- Nc machining technology is generally divided into rough machining, medium rough chamfering, semi-finishing and finishing. For rough processing, try to use a larger tool, in the range of machine power or tool can withstand, with a larger cutting amount, as soon as possible to cut off a large number of workpiece materials. In order to prevent the workpiece from loosening due to cutting vibration during rough machining, the instrument should be checked in time after rough machining, and the tool should be readjusted when necessary. After rough machining, the datum surface can be processed with a light knife to prepare for later calibration. For the workpiece with complex cavity, due to the use of larger tooling, there will be a large number of residual angles, so it is necessary to use a smaller tool than tooling for secondary roughing or chamfering. In order to reduce tool loss, semi-finishing can be carried out when the processing area is relatively large. In order to prevent excessive cutting, each step must leave enough margin for finishing. In general, try to check the machine tool, take out qualified, and then prepare for the next step of processing.
