Precision parts processing is an indispensable part of modern manufacturing industry, requiring high dimensional accuracy of parts, good shape accuracy and excellent surface quality. In precision parts machining, position tolerance is a very important index, which is directly related to the assembly performance and working accuracy of parts.

Position tolerance is used to describe the relative position relationship between specific elements on the part. In the process of parts processing, different features need to meet a certain position relationship, such as parallelism, perpendicularity, coaxiality and symmetry. These position tolerance requirements are determined according to the design requirements and practical application requirements, by comparing the actual measurement results with the design requirements, to determine whether the position accuracy of the part meets the requirements.

Position tolerance control is very important in precision parts machining. First of all, the control of position tolerance can ensure the assembly performance of the part. In the assembly process of parts, if the position tolerance is too large, it will lead to the parts can not be correctly installed and matched, affecting the quality and efficiency of assembly. Therefore, by controlling the position tolerance, the assembly performance and assembly accuracy of the parts can be ensured.

Secondly, the control of position tolerance is also very important for the working accuracy of the part. In some applications that require high working accuracy, such as precision instruments, aerospace equipment, etc., the control of position tolerance is directly related to the working accuracy and stability of parts. If the position tolerance is too large, the working error will increase, affecting the performance and accuracy of the whole system.

In order to control the position tolerance, many means and methods are adopted in the machining of precision parts. First of all, through reasonable process procedures and the selection of processing tools, the error and deformation of parts can be reduced during processing. Secondly, high-precision measuring equipment is used to detect the size and position of the parts, and problems in processing are found and corrected in time. Finally, strengthen the control and management of the processing process to ensure that each link meets the design requirements and ensure the position tolerance control of the parts.

Position tolerance in precision parts machining is a very important index, which is directly related to the assembly performance and working accuracy of parts. Through reasonable process procedures and the selection of processing tools, high-precision measuring equipment and strict quality control, position tolerances can be effectively controlled, the quality and performance of parts can be improved, the needs of customers can be met, and the development of modern manufacturing industry can be contributed.
