Evaluation of diamond tool wear
The International Journal of Advanced Manufacturing Technology, 2004The present study proposes a test protocol regarding the wear of sintered diamond tools. A set of parameters, which characterise the grade of wear, and its relationship with the cutting ability of the examined tools, are established. The proposed protocol establishes the procedure and the equipment for carrying out the tests, the features of the ...

Cutting Tool Materials and Tool Wear
2014The chip formation in machining operations is commonly accomplished by a combination of several elements working together to complete the job. Among these components, cutting tool is the key element that serves in the front line of cutting action. Cutting action becomes a challenge when it comes to machining difficult-to-cut materials. Titanium and its

Tool Wear Monitoring at Turning
Journal of Engineering for Industry, 1994A new method for automatic tool wear monitoring at turning has been developed based on the analysis of the continuous acoustic emission (machining noise) generated by the tool during machining. Different wear types (wear of tool flank face and tool chipping) result in changes in the different characteristic values of the noise signal.

Tool wear mechanisms in machining
International Journal of Machining and Machinability of Materials, 2007Most of tool wear studies are classified as empirical (e.g. Taylor's equation); thus, they do not bring out the physical nature of the wear phenomenon. Consequently, tool life in general cannot be predicted by extending the result from one study. By understanding the physics behind the process, the important wear mechanisms can be identified.

Tool Design, Tool Wear and Tool Life
2009Metal cutting is a process of removing material from a workpiece in the form of chips using single- or multi-point cutting tools with a clearly defined geometry. To some extent, the performance of a cutting tool determines the cutting behaviour and the process capability.

Tool-Wear Monitoring and Control
Manufacturing Engineering and Materials Handling, Parts A and B, 2005This paper presents, a control methodology based on experimental data of the tool wear as a function of cutting variables. In automatic machine tools there is strong need to control the tool wear by adjustment of the cutting parameters. In this connection, a control system, which can adjust the cutting parameters for a desired wear rate, is necessary ...

Basic Investigation of Tool Wear
Journal of Engineering for Industry, 1963This paper treats a fundamental investigation of tool wear and tool life mainly from the viewpoint of flank wear. The result reveals that the mechanism of tool wear in turning can be classified into two basic types: The mechanical abrasion which is directly proportional to the cutting distance and independent of the temperature; and the other is, so to

Tool wear prediction in turning
Journal of Materials Processing Technology, 2004Abstract The aim of the present work is to develop a reliable method to predict flank wear precisely in a turning process by developing a mathematical model and comparing it with the experimental results. Some important factors like the index of diffusion, wear coefficient, rate of increase of normal load with respect to flank wear and the hardness ...
