Background. The use of computer simulation of machining equipment al-lows at the stage of its design, without manufacturing a prototype, to determine the limita-tions of its design and to develop actions to eliminate them. The aim is to increase the productivity of machine tools.
Materials and methods. Proposed for computer simulation of machine equipment to use the SolidWorks software with a variety of applications. Adopted reasonable assumptions in the development of three-dimensional models of nodes, allowing to assess the values of their elastic, temperature deformations, dynamic displacement ele-ments as well as thermal and strength calculations.
Results. Developed 3D models of host specific machine and appropriate calculations.
Conclusions. The results obtained in the de-sign stage of machine-tool equipment to evaluate their performance, and, if necessary, to develop actions for improving the design of their sites.
