Process characteristics of CNC machining

In the field of machining, CNC machining, also known as computer gong machining, belongs to CNC machining equipment. It abides by the laws of machining and cutting, and is roughly the same as the machining process of ordinary machine tools. Because the CNC processing plant is an automatic processing equipment that applies computer control technology to mechanical processing, it has the characteristics of high processing efficiency and high precision. The process arrangement is more detailed and thorough.

The CNC machining process includes the selection of tools, the determination of cutting parameters, and the design of the cutting process route. CNC computer gong processing technology is the basic core of CNC programming. Only with reasonable technology can high-efficiency and high-quality CNC programs be processed. The criteria for measuring the quality of a machining program are: with less machining time, less tool wear and better results.

CNC computer gong machining process is part of the overall machining process of parts, or even a process. When processing, it is necessary to cooperate with other front and rear processes to meet the assembly requirements of the overall robot or automation equipment accessories, so that qualified parts can be processed.

The machining process of computer gongs can be divided into roughing, medium-roughing, semi-finishing and finishing. For rough machining, a larger knife should be used as much as possible, and a large amount of workpiece material should be quickly removed as far as possible within the range that the machine power or the tool can bear. In order to prevent the workpiece from loosening due to the cutting vibration during roughing, the table should be checked in time after roughing, and it is necessary to recalibrate the tool. After roughing, the finishing smooth knife of the reference surface can be carried out to prepare for the future calibration check. For complex machined parts, since a larger tool is used for roughing, a large amount of allowance remains at the corner, and a smaller tool than that used for roughing is used for secondary roughing or corner cleaning. In the case of a relatively large machining area, semi-finishing can be performed in order to reduce tool wear. The above processing process leaves enough allowance to prevent over-cutting, and then carries out the finishing process. In the process of finishing, in general, try to check on the machine tool, and remove it to prepare for the next piece of processing after passing the test.
