Method of Structural Design of Heavy Machine Tools Viktor Kovalov, Yana Antonenko, Predrag Dais Abstract This paper presents a method of arr
2、angement the frames of heavy lathes with dispersed forces along the coordinate axes of the loads that act on the machine while it is running. Mathematical models of large bearing systems, taking into account typical and boundary loads are developed. The field trials of the action of frames are condu
3、cted. We analyzed the movement of the frame on the coordinate axes due to its loading. A solid modeling and research of support of heavy lathe using a package Solid Works Simulation are conducted. The perspective ways to further improve the accuracy of machine tools are proposed. Keywords: accuracy;
4、 rigidity; support; frame of support; a technological system; modeling. 1. Introduction Modern trends in mechanical engineering, the transition to the use of automated machine tools have requirements to increase accuracy of the size and quality of the machined surfaces of machine parts and devices.
5、This is due to the appearance of new more precision machines and instruments. It is no accident since the 40s of the 20th century every 20 years the accuracy of the technique increases on the order. In the design and operation of technological processing systems there is a continuously increasing de
6、mand to enhance their accuracy characteristics. Currently, as a result of theoretical and experimental research of a large number of scientists accumulated considerable material on technological quality assurance processing that allows to create mathematical models of management of process machining l. However, the efficiency of these models does not always give a satisfactory result, since they insufficiently take into account the impact of the complex multi-axis elastic system of machi
