The machining efficiency of CNC machining center mainly includes the following aspects of evaluation:

Machining time: machining time is one of the important indicators to evaluate the efficiency of CNC machining. The shorter the machining time, the higher the processing efficiency. The calculation of machining time usually includes program preparation time, clamping positioning time, machining time and tool change time. Among them, the program preparation time refers to the time of writing processing programs and adjusting processing parameters, the clamping positioning time refers to the installation and positioning time of the workpiece on the fixture, the machining time refers to the actual machining time of the CNC machine tool, and the tool change time refers to the time of tool replacement. By accurately measuring and analyzing these times, the machining efficiency of the CNC machining center can be assessed.

Machining accuracy: machining accuracy is another important indicator to measure the efficiency of CNC machining. The higher the processing accuracy, the better the processing quality, and the higher the processing efficiency. Machining accuracy usually includes profile accuracy, dimensional accuracy and surface roughness. Contour accuracy refers to the degree of consistency between the geometry of the workpiece and the design requirements, dimensional accuracy refers to the deviation between the workpiece size and the design size, and surface roughness refers to the finish of the workpiece surface. Through the detection and evaluation of these indexes, the machining accuracy of NC machining center can be judged and its machining efficiency can be evaluated.

Productivity: productivity is a comprehensive index to evaluate the efficiency of CNC machining. Productivity includes not only machining time and processing accuracy, but also production costs, energy consumption and equipment utilization. The increase of productivity can effectively improve the machining efficiency of CNC machining center and realize the utilization of resources. The methods to increase productivity include increasing the operation rate of equipment, optimizing the production process and improving the skill level of operators. Through the comprehensive evaluation of productivity, the machining efficiency of NC machining center can be evaluated more comprehensively.

Process innovation: process innovation is one of the important factors in evaluating the efficiency of CNC machining. With the progress of science and technology and the change of market demand, the processing technology is also constantly updated. The use of new processing technology and method can improve production efficiency, reduce production costs, but also improve product quality. Therefore, innovation awareness and ability is one of the important indicators to evaluate the efficiency of CNC machining. Only by constantly improving the technical level and innovation ability can we be invincible in the fierce market competition.

In summary, the machining efficiency of CNC machining center is mainly assessed by machining time, machining accuracy, productivity and process innovation. Only by comprehensively considering these factors can we accurately assess the processing efficiency of CNC machining centers and provide more powerful support for the development of enterprises. In the future development, CNC machining center will continue to be committed to improving processing efficiency, improving product quality, reducing production costs, and contributing to the sustainable development of enterprises.
