Analysis of mathematical models of drilling describing surface quality and tool overload protection aspects

Abstract

In the article, taking into account the specifics of the drilling operation, especially deep, the analysis of the known mathematical models describing the aspects of ensuring the accuracy and quality of the holes is presented. Based on the results of the analysis of the known mathematical models, it is concluded that the available dependences cover only part of the problem of improving the accuracy, aging the shape of the hole and the quality of its surface. The expediency of development of mathematical models more widely covering technological systems of drilling of holes, especially in difficult materials is shown. An example of the work of the system of stabilization of the load on the drill, where the correction of adjustable values is carried out by the current drilling depth.
