Rational reduction of work in progress when assembling parts of a product using the group interchangeability method

Abstract

The article discusses the method for interchangeability method. To reduce the volume of work in progress, the design of a fixed combined compensator is developed, which provides stepwise regulation. The article reducing the work in progress by stepwise regulation in multilink dimension chains when assembled using the group proposes a rational technology for the use of combined compensator, taking into account the peculiarities of the group interchangeability method. In order to reduce the work in progress during assembly using the group interchangeability method, two ways of using the combined compensator have been developed: 1 - the inclusion of a compensator in each dimensional chain collected by the group interchangeability method; 2-application of the compensator only at the stage of formation of work in progress during group assembly by replacing one of the parts with it. The peculiarity of the methods is the use of the informational advantage of group assembly — information about the actual dimensions necessary for sorting parts into groups. This eliminates the step of measuring the closing link during assembly and simplifies the design of the compensator, reducing the number of control steps.
