How to improve the precision and efficiency of precision sheet metal processing?
Precision sheet metal processing accuracy is not only a representative of the company’s processing strength, but also a test for sheet metal processing masters! Whether it is a sheet metal processing factory or an individual who performs sheet metal processing operations, it may often occur that the sheet metal processing accuracy is not ideal. Common methods to improve sheet metal machining accuracy include original error reduction method, original error compensation method, original error transfer method, original error equalization method and original error equalization method, which are commonly used methods to increase the sheet metal machining accuracy.
Original error reduction method: In production, if errors are found, first find out the main factors that affect processing errors, and then find ways to eliminate or reduce these factors. For example, when machining parts with contours, the shape error of the forming tool and the installation error of the tool are mainly reduced.
Original error compensation method: artificially create a new error to offset the original error in the process system. When the original error is negative, the human error takes a positive value, otherwise it takes a negative value, and try to make the two equal.
The original error equalization method: If the positioning error is large, some original errors can be differentiated. That is, the original error is divided into N groups according to its size, the range of each group of blank errors is reduced to the original 1/n, and then the processing is adjusted according to each group.
Original error averaging method: For parts with higher machining accuracy, the averaging method can be used. That is to compare closely related surfaces with each other, find out the differences from the comparison, and then perform mutual correction or mutual reference processing, so that the error of the workpiece surface is continuously reduced and averaged.
Original error transfer method: Under certain conditions, the original error of the process system can be transferred to the direction of the machining error or other aspects that do not affect the machining accuracy. For example, when the accuracy of the machine tool cannot meet the machining requirements of the parts, we can find a way to transfer the geometric error of the machine tool to the aspect that does not affect the machining accuracy.
