This paper discussed the behavior of cutting tool in terms of tool wear, tool life and surface roughness when machining an AISI D2 hardened steel. An experimental test was conducted at different cutting speeds (Vc) and radial depth of cut (ae) using PVD TiAlN coated carbide tool under dry condition. Tool failure modes and tool wear mechanism for all cutting tools were examined at various cutting parameters. Flank wear was found to be the predominant tool failure for cutting tools. The highest volume material removal (VMR) attained was 3750 mm3 meanwhile the highest tool life (TL) was 9.69 min. The surface roughness (Ra) values from 0.09 to 0.24 μm can be attained in the workpiece with a high material removal. The relationship of tool wear performance and surface integrity was established to lead an optimum parameter in order to have high material removal, maximum tool life as well as acceptable surface finish.

Hardened materials like AISI H13 steel are generally regarded as s difficult to cut materials because of their hardness due to intense of carbon content, which however allows them to be used extensively in the hot working tools, dies and moulds. The challenges in machining steels at their hardened state led the way to many research works in amelioration its machinability. In this paper, preheating technique has been used to improve the machinability of H13 hardened steel for different cutting conditions. An experimental study has been performed to assess the effect of workpiece preheating using induction heating system to enhance the machinability of AISI H13. The preheated machining of AISI H13 for two different cutting conditions with TiAlN coated carbide tool is evaluated by examining tool wear, surface roughness and vibration. The advantages of preheated machining are demonstrated by a much extended tool life and stable cut as lower vibration/chatter amplitudes. The effects of preheating temperature were also investigated on the chip morphology during the end milling of AISI H13 tool steel, which resulted in reduction of chip serration frequency. The preheating temperature was maintained below the phase change temperature of AISI H13. The experimental results show that preheated machining led to appreciable increasing tool life compared to room temperature machining. Abrasive wear, attrition wear and diffusion wear are found to be a very prominent mechanism of tool wear. It has been also observed that preheated machining of the material lead to better surface roughness values as compared to room temperature machining.

Rapid tool wear is a major demerit of high-speed milling (HSM) applied to cutting of hardened steels, especially the AISI D2. This paper presents an attempt to maximize the tool life by experimentally investigating the effects of cutter’s helix angle, workpiece material hardness, milling orientation, and minimum quantity of lubrication upon tool wear in high-speed side milling of AISI D2, using coated carbide cutters. Effects of these four parameters were studied also upon surface roughness. Statistical analysis upon experimental data revealed that milling orientation was the most significant factor for tool life as well as for surface roughness. The paper also describes the mechanisms of wear undergone by the tools, by making use of SEM photographs and EDS microanalysis. The major wear mechanisms were chipping, adhesion, and diffusion.

Aluminum 6061 is a common alloy which is widely used in aerospace and yacht construction industry. Generally machining of aluminum alloys inherently generates high chip sticking on tool face and changes the tool edge geometry, which not only reduces tool life but also impairs the product surface quality. This study investigated the tool life and tool wear mechanisms besides evaluating surface roughness in various cutting conditions to attain finest possible surface with minimum tool wear. Turning experiments performed under dry orthogonal cutting of Al6061 using carbide CVD tri-phase coated inserts with constant depth of cut, various cutting speeds and feed rates. Insert’s flank and rake faces analyzed to assess wear mechanisms. Additionally Scanning electron microscope (SEM) employed to clarify different types of wear. Surface integrity and effect of built up edge in deviating surface roughness were studied in each cutting condition. Additionally results of experiments demonstrated that built up edge took over cutting edge and with sacrificing surface roughness, tool life increased by decreasing pace of abrasive wear propagation on flank face. According to these experiments the main reasons of flank wear were abrasive and adhesion of aluminum on tool face.

The milling experiments were carried out using TiAlN and PCD coated carbide tools in high speed milling Ti6Al4V to compare and analyze tool wear and tool life of the two kinds of coating carbide tools. In addition, the effect of cooling and lubricating on tool wear is also studied. The results showed that fluid environment is not suitable for milling Ti6Al4V. PCD coating carbide tool can effectively increase the life of tool in high speed milling of Ti6Al4V.
