Tool Wear Mechanisms

An experimental investigation of wear mechanisms in high-speed turning of superalloy GH2132 with Al2O3-based ceramic was conducted under dry cutting condition. The tool wear mechanisms were characterized by observation of tool wear morphology using scanning electron microscopy (SEM) and detection of the element distribution of the worn tool surface utilizing energy dispersive X-ray spectroscopy (EDS). The results of turning experiments indicated that the major wear mechanisms of the ceramic cutting tool were synergistic interaction between abrasive wear and adhesive wear, and meanwhile the micro-chipping was also observed. It is also shown that cutting distance of the Al2O3-TiC ceramic cutting tool at the speed of 420 m/min was higher than that of the speed of 360 m/min and 540 m/min.

Tool Wear Mechanisms

Pure iron is a kind of high plasticity and toughness material. In the process of cutting pure iron, the tool wear is very serious. In this paper, three kinds of cutting tools KC5010, K313 and 1105 are used in the cutting pure iron process and the tool wear tests in dry cutting condition with different cutting parameters have been carried out. According to the results, the tool wear mechanisms and tool life of three kinds of cutting tools have been compared and analyzed. It is concluded that the tool life of K313 is better than KC5010 and 1105 and the three kinds of tool mechanisms are primarily adhesion wear, diffusion wear and oxidation wear.

In the present study, high-speed and ultra-high-speed face milling of AISI H13 steel (4647 HRC) was conducted in order to acquire a thorough understanding of the Al2O3-based micro-nanocomopsite ceramic cutting tool AWT10 wear mechanisms in high-speed hard milling. For different cutting speeds, the typical tool wear mechanisms is analyzed and compared. The analysis of the tool wear show that abrasive wear, adhesive wear, spalling and breakage are the primary wear mechanisms of AWT10 when cutting speed reaches 3000m/min. Micro-nanocomposite ceramic material AWT10 has favorable property of shock resistance. Improved cutting speed is in favor of cutting force reduction.

Tool Performance

One of the most significant factors in machining process or metal cutting is the cutting tool performance. The rapid wear rate of cutting tools and cutting forces expend due to high cutting temperature is a critical problem to be solved in high-speed machining process, milling. Near-dry machining such as minimum quantity lubrication (MQL) is regarded as one of the solutions to solve this problem. However, the function of MQL in milling process is still uncertain so far which prevents MQL from widely being utilized in this specific machining process. In this paper, the mechanism of cutting tool performance such as tool wear and cutting forces in MQL assisted milling is investigated more comprehensively and the results are compared in three different cutting conditions which is dry cutting, wet cutting (flooding) and MQL. The MQL applicator is constructed from a household grade low-cost 3D printing technique. The chips surface of chips formation in each cutting condition is also observed using Scanning Electron Microscopy (SEM) machine. It is found out that wet cutting (flooding) is the best cutting performance compare to MQL and dry cutting. However, it can also be said that wet cutting and MQL produced almost the same value of tool wear and cutting forces as there is negligible differences in average tool wear and cutting forces between them based on the experiment conducted.

Ultra High Speed

This paper explores the wear mechanisms of a Sialon ceramic tool in ultra high speed turning of Nickel-based alloy Inconel 718. Microstructures of the chips are also investigated. Stereo optical microscope and scanning electron microscope (SEM) are employed to observe worn surfaces of the tool produced by various wear mechanisms and morphological features of chips. In addition, the elemental compositions of wear products are evaluated by energy-dispersive X-ray spectroscopy (EDS). As a result of the study, wear mechanisms identified in the machining tests involve adhesive wear and abrasive wear. At the initial stage of cutting process, crater wear and flank wear are the main wear patterns. At the rapid wear stage, the SEM and EDS results showed that the adhered elements of Inconel 718 alloy on the tool rake face such as Ni, Fe and Cr accelerated the tool wear rate. Meanwhile, it was found that the chip morphology was serrated type under ultra high speed cutting condition, furthermore, the tendency of serration of the chip increased with the increase in cutting speed and feed rate.

GCr15 bearing steel was turned with PCBN cutting tools in a manner of hard and dry cutting, and the characteristics and morphology of rake and flank face of PCBN cutting tools were observed, the element distribution of different regions of rake and flank face of PCBN cutting tools were tested and analyzed by use of EDS, and finally the wear mechanisms of PCBN cutting tools were discussed. The results showed that the wear areas of rake and flank face of PCBN cutting tools were small and mostly concentrated near the tip and sub-chamfering, and the reason was mechanical, oxidation, chemical and phase transition wear, which resulted in the joint action of tool wear.

A multi-scale and multi-phase nanocomposite ceramic cutting tool material Al2O3/TiC/TiN(LTN) with high comprehensive mechanical properties has been successfully fabricated by means of adding micro-scale TiC and nano-scale TiN particles. The cutting performance and wear mechanisms of this advanced ceramic cutting tool were researched by turning two kinds of hardened steel 40Cr and T10A respectively. Compared with the commercial ceramic tool LT55, LTN showed a superior wear resistance with certain machining parameters. The machining tests indicated that the new materials tool is suitable for continuously dry cutting of hardened steel with high hardness at high speed.
