Precision positioning and adjustment errors in the machining industry!

In the field of mechanical processing industry, the entire process of production and processing of mechanical parts that meet the standard is divided into various types. Among them, the accuracy positioning and adjustment error are part. The machining precision positioning refers to: the benchmark does not overlap the error. The benchmark used to clarify a surface specification and position on the mechanical part drawing is called the design plan benchmark. The process flow chart is used to clarify the specifications and parts on which the process flow is produced and processed after surface production and processing is called the process flow benchmark. When carrying out production processing on a CNC lathe, multiple geometric factors on the workpiece must be selected as the positioning datum during production and processing. If the positioning datum used does not overlap with the design plan datum, it will cause a non-overlapping error of the datum. Inaccurate error in manufacturing of positioning pair. The positioning components on the tooling fixture are unlikely to be produced and manufactured according to the basic specifications, and their specific specifications (or parts) are allowed to vary within the scope of the dimensional tolerances required by them. The positioning surface of the workpiece and the positioning components of the tooling fixture form a positioning pair with each other. Because the manufacturing of the positioning pair is inaccurate and the gap between the positioning pair is caused by the large part change of the workpiece, it is called the inaccurate error of the manufacturing of the positioning pair.

Look at the adjustment error of mechanical processing: it means that in each process flow of mechanical processing, the adjustment work of the processing technology system software must be carried out in one way or another. Because the adjustment is unlikely to be accurate with certainty, adjustment errors are caused. In the processing technology system software, the accuracy of the parts between the workpiece and the CNC blade on the CNC lathe is ensured according to the adjustment of the CNC lathe, CNC blade, tooling fixture or workpiece, etc. When the initial accuracy of CNC lathes, CNC blades, tooling fixtures and workpiece blanks, etc., all meet the requirements of the processing technology without considering the dynamic elements, the harm of adjustment errors has a fundamental effect on the production and processing accuracy.

The above is the description of the accuracy positioning and adjustment error of the processing network machinery and equipment in Dongguan's mechanical processing industry. Thanks for sharing!
