Research and calculation of the connected dimensional chains by the example of providing indicators of rotary indexing tables accuracy

In this article, we present the results of analysis of dimensional links in a structure of a rotary-dividing table. We show that dimensional links have a bearing on indicators of geometric accuracy. It is revealed that the dimensional chains which describe a process of forming accuracy indicators are related. It is established that some components of the dimensional chain change their direction in the process of achieving accuracy. In order to decrease alabour input of assembly some proposals based on the result of calculationare developed.
