Research on optimization of freeform surface operation

Abstract

Nowadays, many manufacturing companies need to face competition both in domestic and international level. Due to this circumstance, manufacturers recognize that one useful method to enhance their competence is reducing the lead-time of manufacturing. There are many researchers focused on minimize the time of actual cutting, tool path optimization and energy consumption optimization etc. However, few researchers have investigated the operation optimization of CNC machine that integrating multiple ways to reduce the operation time of freeform surface cutting. For example, integrating tool path calculation optimization and machining parameters optimization together for the sake of providing an optimization solution package to enhance the efficiency of manufacturing. This master thesis will investigate the main optimization methods of tool path (Iso parametric, Iso planar and Iso scallop), as well as prediction of operation time and energy consumption optimization. Then we will provide several approaches for machining a surface on a metal strip to research the effect of different tool paths generation such as Iso parametric and Iso scallop etc. depend on NC code on machining time and quality
