What are the different types of cutting tool materials?

Different Types of Cutting Tools Materials and Their PropertiesCarbon tool steel.High speed steel tool (HSS)Cemented carbide.Ceramics tool.Cubic boron nitride Tool (CBN)Diamond tool.

What is the main cause of tool wear?

Abrasive wear is mainly caused by the impurities within the workpiece material, such as carbon, nitride and oxide compounds, as well as the built-up fragments. This is a mechanical wear, and it is the main cause of the tool wear at low cutting speeds.

How do you calculate tool life in minutes?

Find the tool life equation if a tool life of 80 min is obtained at a cutting speed of 30 m/min and 8 min at 60 m/min. ADVERTISEMENTS: Tool life T2 = 8 min, cutting speed V2 = 60 m/min. Hence, Tool life equation becomes VT0.3 = C.

Which carbides are used for cutting tools?

Cemented carbide is a hard material used extensively as cutting tool material, as well as other industrial applications. It consists of fine particles of carbide cemented into a composite by a binder metal.

How hard can steel carbide cut?

Combining this coating with nanograin carbide means our X5070 cutters can machine high hardened steels up to 70 HRc at ultra-high speeds and feeds with incredible tool life!

Which is the cheapest tool material?

Carbon Tool Steel1) Carbon Tool Steel: It is one of the cheapest material used in cutting tools for different machining processes. This material is also easy to make. These carbon tool steel has a composition of 0.6-1.5 % carbon and very small amount of Mn and Si which are less than 0.5%.

How do you stop wearing tool?

If the wear land becomes excessive or causes premature tool failure, reducing the cutting speed and optimizing coolant usage can help. High Efficiency Milling (HEM) toolpaths can help reduce wear by spreading the work done by the tool over its entire length of cut.

Which is main criteria to increase the tool life?

As identified in the text, tool life criteria used in production include (1) complete failure of the tool, (2) visual observation of flank or crater wear, (3) fingernail test to feel flank wear, (4) sound of the tool, (5) chip disposal problems, (6) degradation of finish, (7) power increase, (8) workpiece count, and (9 …
