“…Flank wear, chipping and catastrophic failure are other causes of tool rejection when machining nickel-based alloys. SEM examination of the carbide tools used to machine nickel-base alloys has shown a layer of 'distributed' material beneath the crater and the cutting edge [5]; in this layer the tungsten carbide grains being smaller and more rounded than in the original material. The crater originated immediately behind the cutting edge, i.e.…”

In this study the performances of some commercially available carbide inserts when machining Hastelloy C-22HS was investigated under scanning electron microscopy (SEM) for wear mechanisms and other microstructure defects. Carbide inserts coated with TiCN/TiN and TiALN/ TiN experienced severe intergranular fractures and cracks. High temperature causes the layer of the coating to wear off and subsequently the inserts damaged at fast rates. Both types of inserts suffered from high crater wear and thermal cracking. Most of the wear occurred at the nose and flank of the inserts. Generally, it was observed that carbide coated with TiALN/ TiN cutting tool performed better than carbide coated TiCN/TiN cutting tool when milling Hastelloy C-22HS

Wear maps for some uncoated cutting tools

The method of using maps and diagrams to present wear rates and wear mechanisms, as well as showing the relationships between them, has been app2ied to cutting tools. In this s u m m a y paper, wear maps obtained earlier for uncoated high-speed steel ( H S S ) INTRODUCTlONA primary cause of cutting-tool replacement in the manufacturing industry is tool wear. Its impact on a nation's economy can be gauged from a report that a significant portion of the estimated €20,000 million spent per m u m on metal cutting in the UK in the early 1980s was used for replacing worn tools, and about $4,000 million was wasted every year due to inefficient application of modern tools and tooling techno1ogy.l Although this data is more than a decade old, it nevertheless highlights the severity of this problem. A sizeable reduction in the total operating cost to industry could therefore be achieved if the cutting tools could be used for longer before being replaced; productivity could also be increased as less time would be spent setting up these tools when they were replaced. One way to achieve this goal is to make cutting tools from more wear-resistant materials, another is to use the tools in conditions that will result in lower rates of tool wear. The use of more wear-resistant cutting tools invariably increases operating costs,
