Development of Aplication for Analysis of Machinability Index
Journal Title: Tribology in Industry - Year 2009, Vol 31, Issue 1
Abstract
Rapid development of new materials, cutting tools and cutting fluids promote research of machinability for new materials and tribological characteristic of cutting tools and cutting fluids. Material machinability is very complex category and it must be considered from different points of view and with different machining requirements. It depends upon a number of influencing factors, primarily associated with mechanical, structural and thermal characteristic of working material and it is expressed through output parameters from machining process (tool wearing, cutting forces, quality of machining surface, etc.). This paper presents developed application, which gives results for machinability index for group of tough machined materials. Application is fundamentally developed on experiments, when measuring cutting force at turning operation for group of tough machining materials, and also experiments done on tribometer „Block on Disk“. Application consists of several databases, developed modules for cutting forces calculation, experimental relations for evaluation of friction coefficient at clearance surface of cutting tool. Output indicators of application are comparative graphical and analytical results of machinability index for analyzed group of tough machining materials.
