Cutting tool crater wear measurement with white light interferometry

Wear, 2004
In this paper we propose the use of white light interferometry for measurement of wear craters on cutting tool inserts. It was briefly discussed interferometry principles and tool wear during dry metal cutting, after which a discussion of the application of interferometry to cutting tool wear measurement was described. A comparison of the profiler data

An Analysis of Crater Wear Based on the Adhesive Wear Mechanism

1976
A wear equation based on the adhesive wear mechanism is derived for the conditions occurring in the tool-chip contact region. In deriving this equation the time-temperature dependence of the adhesion occurring at the points of contact is taken into consideration.

Wear mechanisms in ball-cratering tests with large abrasive particles

Wear, 2004
Abstract Three-body abrasive wear resistance of mild steel and 27%Cr white cast iron was investigated using a ball-cratering test. Glass beads, silica sand, quartz and alumina abrasive particles with sizes larger than 200 μm were used to make slurries.

Modelling of CBN tool crater wear in finish hard turning

The International Journal of Advanced Manufacturing Technology, 2004
The wear of cubic boron nitride (CBN) cutters, commonly used now in the finish turning of hardened parts, is an important issue that needs to be addressed for hard turning to be a viable technology due to the high costs of CBN cutters and the down-time for tool change. Chipping and tool breakage, which lead to early tool failure, are both prone to take

Cutting tool crater wear measurement by the lapping-comparator technique

International Journal of Machine Tool Design and Research, 1968
Abstract A new contour mapping technique for the investigation of cutting tool crater wear development is presented. A transparent thermoplastic mold of a tool crater is made and lapped to show contour lines on an optical comparator. The lapping-comparator technique is simple and nondestructive.

Local Crater Wear Prediction Using Physics-Based Models

Journal of Manufacturing Science and Engineering, 2010
A physics-based, pointwise model is developed to predict crater profiles of multilayer coated carbides after a series of turning experiments. Dissolution and abrasion mechanisms, which are identified to be the dominant wear mechanisms at the crater, are reformulated into a pointwise or local quantity to predict the crater profiles based on the ...

A computer algorithm for flank and crater wear estimation in CNC turning operations

International Journal of Machine Tools and Manufacture, 2002
Abstract In order to increase the productivity of turning processes, several attempts have been made in the recent past for tool wear estimation and classification in turning operations. The tool flank and crater wear can be predicted by a number of models including statistical, pattern recognition, quantitative and neural network models.

Deduction of flank and crater wear from measurements of the total volumetric wear rates of radioactive tools

Wear, 1980
Abstract Some simple considerations of the total volumetric wear rates measured in tool life tests using radioactive tools provided information on the separate contributions of flank and crater wear effects. In orthogonal cutting tests with irradiated high speed steel tools there was reasonable agreement between the results obtained using the present

Crater wear characteristics of an Fe-diffused carbide cutting tool

Journal of Materials Processing Technology, 2003
Abstract The generation of a crater wear is affected by many factors such as characteristics of work and tool materials, cutting conditions and lubrication at a tool–chip contact area. The purpose of this research is to clarify the effect of Fe-diffused layer on a crater wear of a carbide cutting tool.

On the mechanism of tool crater wear during titanium alloy machining

Wear, 2017
Abstract Tool crater wear is a major cause of accelerated tool failure during the machining of titanium alloy components. This paper presents a static diffusion couple method which replicates the complex reaction mechanisms occurring at the tool-chip interface during machining and is validated with dynamic turning trials.
