Method for Taking into Account Measurement Errors When Sorting Elements into Selective Groups

The problem of one-parameter one-variant selective set-making and assembly of two elements forming a precision one-parameter joint is considered. The key step in the selective assembly of products is the sorting of elements into groups by measuring their parameters, accompanied by mistakes caused by measurement errors. An analytical model has been built to take into account the influence of measurement error on the sorting process and to determine the number of assembly sets. A method is proposed to determine the number of suitable assembly sets from their total amount. The simulation results are presented. The results obtained are the basis for constructing models of more complex selective assembly systems.
