Compensation of defective workpiece based on adaptive calculation of technological dimensions

Abstract

Dimensional analysis of technological processes is a key method in terms of reducing the probability of defecting and compensating for the resulting reject associated with dimensions, allowances and tolerances. On the basis of the general method of calculating technological dimensions with adaptation, the problem of compensating the resulting defect is first solved by means of dimensional analysis. The article discusses an example of the calculation of linear technological dimensions with adaptation in order to compensate for defect, according to the results of preliminary control of a particular workpiece and the implementation of a separate calculation of sizes and allowances. The calculation is carried out using the processing scheme, graph, dimensional chain equations and a computer program. As a result of the study, it is found that the calculation of linear technological dimensions with adaptation allows reallocation of the actual values of allowances at each operation and thereby provide compensation of the defect.
