Investigation into crater wear in drilling

International Journal of Machine Tools and Manufacture, 2000
This paper presents the effects of spindle rotational speed and feed rate on the crater wear along the lip of a drill. A theoretical model has been developed to correlate the cutting parameters with crater wear through the cutting forces. A series of experiments was conducted to study the performance of the drilling process in terms of drill wear and ...

3D measurement of crater wear by phase shifting method

Wear, 2006
In this paper, a new method of non-contact tool wear measurement is presented. It employs a phase shifting method using fringe patterns to measure crater wear by constructing a 3D map of the tool insert. Four fringe patterns with various phase-shifts are projected onto the rake face of the tool upon which four gray-level images are captured. By solving

Complex wear measurement on thin coatings by the cratering method

Lubrication Science, 2009
AbstractBall cratering and rotating wheel tests are useful techniques for abrasive wear resistance evaluation of thin coatings.Nevertheless, such techniques involve significant experimental errors, coming from equipment deficiencies and changes in wear response depending on test parameters.In case of rotating wheel test, common instrumental errors are:

Research on Crater Wear Monitoring in Turning

Applied Mechanics and Materials, 2013
Tool wear is a significant research field in metal cutting because it affects not only the tool cost and replacing time, but also the productivity and surface quality. Tool wear monitoring is a key technology in tool wear research. A series of turning tests with different cutting time are implemented.

On the mechanism of crater wear in a high strength metastable β titanium alloy

Wear, 2021
Abstract The primary wear mechanism of WC-Co tools when machining aerospace titanium alloy components is crater wear. The diffusion controlled dissolution and thus the crater wear rate is more apparent when machining the high strength, fatigue resistant metastable β titanium alloys: an expensive class of titanium alloy used in aerostructural ...

On-Line Sensing of Flank and Crater Wear of Cutting Tools

CIRP Annals, 1987
Abstract It is well known the high interest for on line sensing of tool wear with the aim of controlling machine tools productivity from the point of view of quality and quantity. Difficulties in this measurement are also known. This paper describes a sensor based upon the TV image analysis of a worn tool.
