Abstract

In the process of multivariate design of machining technology, one of the important tasks is the selection of optimal cutting conditions at the final transitions of the shaping process, ensuring a given surface quality on a workpiece made of the corresponding material. At the same time, to describe the majority of design procedures for the machining process, there are problems associated with the algorithm for choosing a solution method, response function, and areas of feasible solutions at all stages of processing. In this paper, as an algorithm for solving the problem, it is proposed to use the well-known technique of extreme experimental design, which allows to obtain a mathematical model of the investigated multifactor process with incomplete knowledge of its optimization mechanism. Such a study allows us to simplify the procedure for setting the processing regime of the workpiece at the final stage in the conditions of the existing production, while ensuring the specified quality of the machined surfaces and maintaining the productivity of the forming process. This technique is the subject of consideration in this work.

Highlights

One of the important tasks facing the machine-building enterprises is to ensure high quality of manufactured products while maintaining the required productivity of the machining process.First of all, this concerns the provision of specified qualitative indicators of the processing process at the finishing and finishing stages, where the required height of microroughnesses of the surfaces is directly determined by the choice of rational processing modes in the form of cutting depth t, tool feed s and cutting speed v

The solution to the existing problem is seen in conducting experimental engineering studies for the subsequent construction of mathematical models that allow us to describe the optimal conditions for the course of the machining process, which is especially important at its final stages

Introduction

One of the important tasks facing the machine-building enterprises is to ensure high quality of manufactured products while maintaining the required productivity of the machining process First of all, this concerns the provision of specified qualitative indicators of the processing process at the finishing and finishing stages, where the required height of microroughnesses of the surfaces is directly determined by the choice of rational processing modes in the form of cutting depth t, tool feed s and cutting speed v. This concerns the provision of specified qualitative indicators of the processing process at the finishing and finishing stages, where the required height of microroughnesses of the surfaces is directly determined by the choice of rational processing modes in the form of cutting depth t, tool feed s and cutting speed v These factors, on the other hand, uniquely determine the productivity of the cutting process itself [1].
