Practice of Dimensional Modeling of Assembly Operations Using Static Compensators

The paper presents a process of dimensional couplings modeling in assembly operations using single-circuit graph models, describing the mechanism of individual components mating. The method of incomplete interchangeability is used for the description as being the most common in the current manufacturing conditions. The authors consider the calculations based on the defined mathematical model, which can be applied to single-circuit and multi-circuit dimensional schemes in various manufacturing conditions. For mass production, an algorithm is proposed to determine the scattered field of upper and lower limits of adjusting gaskets. The calculation method is demonstrated using specific examples describing extreme events of interaction between the dimension chains of parts in the assembling department. With that, the nominal controller link is viewed as having a positive reduction ratio.
