Mechanism-Based FE Simulation of Tool Wear in Diamond Drilling of SiCp/Al Composites

Mechanism-Based FE Simulation of Tool Wear in Diamond Drilling of SiCp/Al Composites

The aim of this work is to analyze the micro mechanisms underlying the wear of macroscale tools during diamond machining of SiCp/Al6063 composites and to develop the mechanism-based diamond wear model in relation to the dominant wear behaviors. During drilling, high volume fraction SiCp/Al6063 composites containing Cu, the dominant wear mechanisms of diamond tool involve thermodynamically activ...

Fabrication of Fe-Based Diamond Composites by Pressureless Infiltration

A metal-based matrix is usually used for the fabrication of diamond bits in order to achieve favorable properties and easy processing. In the effort to reduce the cost and to attain the desired bit properties, researchers have brought more attention to diamond composites. In this paper, Fe-based impregnated diamond composites for drill bits were fabricated by using a pressureless infiltration s...

Minimization of Burr Height and Tool Wear in Drilling of Aluminium Metal Matrix Composites Using Desirable-Fuzzy Approach

This paper is focused on minimization of the burr height and Tool wear in drilling of Aluminium Metal Matrix Composites(AMMC) using “Desirable-Fuzzy” approach, which is developed by combining the Desirability Function Analysis and Fuzzy Logic. AMMC samples are prepared based on selected material parameters and drilling experiments are conducted on these samples as per Taguchi OA L27 which is de...
