An overview on the cutting tool factors in machinability assessment

Purpose: This paper is devoted to present and discuss the current trends of cutting tool technological challenges. Design/methodology/approach: The main focus was on tool wear mechanisms, tool life relations and tool life response model. A details search on the literature was conducted and some concluding remarks were made. Findings: The response surface methodologies combined with the factorial design of experiment were found to be very useful techniques for tool life testing. Practical implications: This paper shows that the response surface methodology (RSM) can be used in the design of experiment to develop tool life models for several materials and the same approach can be used for modeling other machinability performance measures (Response) such as surface roughness etc. Originality/value: This paper is designed to be beneficial for researchers working in the machinability area in order to provide an up to date review on the cutting tool technological development.
