Self-Organization of PVD Cemented Carbide Tool When Cutting In718

Abstract

-Tool wear/tool life of PVD cemented coated carbide material in machining superalloy In718 has been studied by different methods. Self-organization theory is one of the effective ways to explain tool wear/tool life. In this paper, worn and fractured surfaces of the cutting tools were characterized by scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). Self-organization of cutting tools during wear process was analyzed through SEM and EDS analysis. The results revealed that built-up edge and oxygen-containing surface film were two forms of tool self-organization in high speed turning of In718 with PVD cemented carbide inserts. Self-organization of the cutting tools took place with all kinds of wear mechanism during cutting. They affected the cutting tools in opposite directions with tool wear mechanisms, reducing the tool wear, protecting the loss of the tool materials effectively.

Reliability Analysis of Alumina-Based Ceramic Cutting Tool's Wear Life by Saddle Point Approximation

“…Cutting tool wears when used in metal cutting, and will lose its cutting ability to a certain degree. So it is of important economic value to conduct a research on attrition [1][2][3] . The reliability of metal cutting tool is that tool's ability to complete its cutting work under the set cutting condition and within the set time, which immediate impact on the quality of the product, work efficiency and the function of the overall system in the productive process, so it is one of the important indicators to measure the performance of cutting cool and of great research significance.…”
