Abstract

The purpose of this Ph.D. thesis is to investigate the problems with increasing the efficiency machining for medium roughing operation turning cycles. Ph.D thesis describes and suggests the possibility of using effective strategies and their application in programming CNC turning centers. Suggested roughing cycles with the use of variable depth of cut will ensure increasing the durability of the cutting tool and the efficiency during turning. The proposed research for the Ph.D. thesis is an experimental work - measuring cutting forces and monitoring of the tool wear on the cutting edge. Ph.D. thesis will provide new insights in theoretical analyzes in turning with the use of variable depth of cut. Work demonstrates and confirms the great value of studying this issue within the theoretical research, which are the basis for practical application and for an immediate practical testing. Ph.D. thesis describes and proposes roughing cycles: decreased cut, turning with the creation of the conical surface, turning with nonlinear methods. This work compares standard machining strategy and newly proposed strategy with the creation of the conical surface (ie. a strategy with variable depth of cut). Important part of experimental work is a detailed analysis of the tool wear on the cutting edge versus time. Individual components of cutting forces are scrutinized and results helping us to understand the cutting process with a variable cut depth. Ph.D. thesis presents variations of integration into the workflow for programming CNC machine tools. In scientific research area shows the trend CAM systems. It suggests possible options of implementation this research into 2-axis turning modules CAM systems.
