China's mold industry has made great breakthroughs. During the development of the mold industry, my country's market has always insisted on innovation and development, and strengthened technical exchanges with developed countries, which greatly improved the strength of my country's mold industry and the market competitiveness of mold companies. At the same time, China's basic pattern as a manufacturing country will not change, and the pace of becoming a manufacturing power will not stop. Instead, it will speed up by promoting transformation and upgrading. This complex and changeable economic situation just provides a stage for mold development.

The actual parameters obtained by any machining method will not be absolutely correct. From the perspective of the function of the part, as long as the machining error is within the tolerance range required by the part drawing, it is considered that the machining accuracy is guaranteed.

Machining accuracy is the degree of conformity between the actual size, shape and position of the three geometric parameters of the surface of the processed part and the ideal geometric parameters required by the drawing. Ideal geometric parameters are uniform in terms of size; in terms of surface geometry, they are absolute circles, cylinders, planes, cones, straight lines, etc.; for mutual positions between surfaces, they are absolutely parallel. , Vertical, coaxial, symmetrical, etc. The deviation of the actual geometric parameters of the part from the ideal geometric parameters is called the machining error.

Machining accuracy and machining error are both terms to evaluate the geometric parameters of the machined surface. Machining accuracy is measured by tolerance grade, the smaller the grade value, the higher its accuracy; the processing error is expressed by a numerical value, the larger the value, the greater the error. High machining accuracy means small machining error, and vice versa.
