FEM Simulation of Tool Wear in Drilling

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...

tool wear modeling in drilling process of aisi1020 and aisi8620 using genetic programming

in manufacturing industry, it has been acknowledged that tool wear prediction has an important role in higher quality of products and acceptable efficiency. being an emerging area of research in recent years, drilling tool wear is an important factor which directly affects quality parameters of machined hole such as hole centring, roundness, burr formation and finished surface. in this paper, t...

“a Study of Tool Wear in Turning of Pure Aluminum and Drilling of Cfrp /ti

Tool wear in turning of pure aluminum and drilling of carbon fiber reinforced plastics (CFRP)/titanium (Ti) stacks was investigated due to their importance in modern manufacturing. Although pure aluminum is a ductile metal while CFRP contains brittle carbon fibers, there exist also few important similarities which impact tool wear. For instance, neither work material contains inclusions harder ...

Detection of tool wear in drilling based on axis position signals

In-process prediction of corner wear in drilling operations

The paper presents an in-process prediction of corner wear in drilling operations by means of a polynomial network. The polynomial network is composed of a number of functional nodes and well organized to form an optimal network architecture using an algorithm for synthesis of polynomial networks (ASPNs). Thrust force or torque in drilling operations has been correlated with corner wear in this...
