In CNC precision machining specific work operations, the "high speed" in high-speed CNC mechanical cutting technology usually refers to the speed of the machine tool's spindle rotation and feed rate. When cutting mechanical equipment, the cutting speed is much faster than the speed used in normal cutting processing, so people often refer to this technology as ultra-high-speed cutting.
The reason why high-speed cutting has become a hot topic in the field of mechanical material processing is mainly due to its obvious advantages compared to traditional cutting.
The feed rate of CNC machining is greatly increased. High-speed cutting has a very fast cutting speed, which can reduce the conventional processing time by at least half and greatly improve production efficiency;
In high-speed cutting processing in CNC precision machining, the processing accuracy is high and has a good effect on parts with poor rigidity and easy thermal deformation. Because when high-speed cutting reaches a certain cutting speed, the unit cutting force will decrease by at least 30%, which is beneficial to reduce the damage to the surface of the workpiece, greatly reduce the surface roughness of the workpiece, and make the workpiece have good physical and mechanical properties;
It can reduce the disadvantage of tool wear and prolong the service life of the tool;
It can efficiently cut impact-resistant materials;
It can effectively reduce the cost of cutting and improve the cutting accuracy and speed.
The concept of tool compensation has been developed for a long time. For tool compensation, its actual role is to reduce errors during programming. In the actual operation process, there is a certain difference between the actual running route of the tool and its theoretical route, which also affects the programming efficiency to some extent.
In the actual process of CNC machining, tool compensation technology is applied, and the actual contour of the production component should be used as the basis for programming to enable the tool to automatically adjust the tool position during CNC machining, thereby reducing human adjustment of the tool position and thus effectively improving the production efficiency of CNC machining. With the development of CNC technology, tool compensation technology is also constantly developing and accumulating experience in practical applications. Tool compensation technology plays an increasingly important role in CNC machining technology.
In the process of continuous development of tool compensation technology, the compensation methods have also been continuously optimized and derived. Traditional tool compensation is a single method. In modern tool compensation technology, there are also tool length compensation and tool radius compensation methods, making tool compensation more comprehensive.
In the actual application process, appropriate compensation methods should be selected according to the actual situation to prevent deviation of the tool trajectory during operation, thereby effectively improving the quality of production. Currently, tool compensation technology is widely used, and the technical level of relevant technical personnel is also constantly improving, which can effectively improve the work efficiency of CNC machining and greatly reduce the workload of programming in CNC machining technology, and provide advanced technology guarantee.
