Increasing of Lathe Equipment Efficiency by Application of Gang-Tool Holder

Issues of machining processes' intensification and increase of metal-cutting equipment efficiency are of priority value in the modern engineering. Application of various methods of reduction of machine time as a result of combining the potential capabilities of equipment and tooling allows increasing of quality parts with necessary characteristics of accuracy. In this article the issues, connected with using multi-cutter processing on lathes for reduce the production cost of processing, are defined. Based on the offered solution, theoretical research, numerical investigation and experimental research were conducted. Mathematical dependences for determining the multi-tool processing errors on a CNC lathe us-ing a gang-tool holder which provide to choose the optimal geometrical parameters of the part for a specific technological solution, was presented. The practical value of the research is in the studying of ways of increasing of lathe equipment efficiency through the possibility of technological process intensification through the use of multiple tooling.
