The design of technological processes for the manufacture of gas-dynamic supports (GDO) of gyroscopes is traditionally based on the use of finishing operations with the use of free abrasive. This leads to a high complexity of manufacturing such devices and complicates mass production. Reducing the labor intensity is possible when the labor-intensive finishing operation with a more productive operation of honing the holes of the GDO is replacing. But such a replacement requires the development of high-precision technology, which implies mathematical modeling of the process of honing the holes of GDO gyroscopes made of ceramic CM-332.
Objective – a mathematical model of the process of honing the holes of GDO gyroscopes made of ceramic CM-332 is developed, which allows for the known shape of the workpiece, the tool used and the technological modes to calculate the geometric shape of the processed hole, and the value of any error.
A mathematical model of honing of precision holes of GDO gyroscopes is developed, which takes into account the main factors of the process, the characteristics of the tool and the technological modes of processing. The dependence of the accuracy of the geometric shape of the processed hole on the characteristics of the tool is determined.
The use of the results of the study made it possible to reduce the labor intensity of finishing operations for processing GDO holes by 10-15 times in the conditions of mass production of gyroscopes.
