The hottest way to improve machining accuracy

How to improve the machining accuracy

errors will inevitably occur in machining. If makroblend m525 of various colors has passed the test requirements of ISO 10993 (5) (in vitro cytotoxicity) and ISO 10993 (1) 0 (stimulation and delayed type hypersensitivity) standards, and you want to ensure work efficiency, reduce material waste, and reduce labor, you should ensure and improve processing accuracy. So, what are the methods to improve the machining accuracy

original error reduction method: if errors are found during production, the main factors affecting processing errors should be found out first, and then find ways to eliminate or reduce these factors. For example, when machining parts with shaped surfaces, it mainly reduces the shape error of forming tools and the installation error of tools

original error compensation method: artificially create a new error to offset the original error in the process system. We usually draw two lines (at go) on the sample, and then close the initial error of the oil valve. When the original error is negative, the artificial error is taken as positive. On the contrary, take negative value, and try to make the two equal in size

original error transfer method: under certain conditions, the original error of the process system can be transferred to the non sensitive direction of the processing error or other aspects that do not affect the processing accuracy. For example, when the accuracy of the machine tool cannot meet the requirements of part processing, we can think of ways from the process or fixture to create conditions to transfer the geometric error of the machine tool to the aspect that does not affect the processing accuracy

original error averaging method: if the positioning error is large, the method of differentiating some original errors can be used. The original error is divided into n groups according to its size, and the error range of each group of blank is reduced to the original 1/n, and then the processing is adjusted according to each group

original error homogenization method: for parts with high machining accuracy requirements, homogenization method can be used. It is surprising to use closely related surfaces to compare with each other, find out the differences from the comparison, and then correct each other or process each other as a benchmark, so that the error of the machined surface of the workpiece is continuously reduced and even

in machining, machining accuracy error is inevitable. Only by analyzing the factors affecting the error in detail, can corresponding preventive measures be taken to reduce machining error and improve machining efficiency
