【 摘 要 】

This article describes optimization of babbit milling processing methods under conditions of reduction treatment of sliding surface area of big bearings using a special machine module. The aim of the optimization is to increase efficiency while maintaining target quality of the treated surface. Optimizable parameters include feed per hob tooth and cutting speed expressed in terms of the mill rotation rate which have the greatest impact on the treatment time and surface quality parameters. The linear programming method is used, and the following engineering constraints are taken: surface roughness, set tool life, main motion drive power, treatment time relevant for the efficient life, allowable cutting temperature. The optimization is performed in two stages: a set of inequalities is solved at the first stage, and the obtained values are adjusted at the second stage.
