Different Types of Cutting Tools- Single point, Multi-point, Solid type, Tipped type,Linear motion, Rotary motion, Roughing tools, Finishing tools. In these, the cutting edge consists of a separate piece of material, either brazed, welded or clamped on to the tool body. Common materials for tips include cemented carbide, polycrystalline diamond, and cubic boron nitride. Tools using inserts include milling cutters (endmills, fly cutters), tool bits, and saw blades.‎Types · ‎Cutting tools with inserts. Different cutting tool materials used for cutting operations in practice are high carbon steel, high speed steel, non -ferrous cast alloys, cemented.

Tools made from Cast Alloys are now limited in use.

Usually, Carbides are made of Tungsten powder and Carbon, mixed in a ratio of weight- Then the next step involves sintering it with Various cutting tools at high temperatures. There is a wide range of grade of Tungsten Carbide available in the Market.

The addition of Cobalt gives increased various cutting tools, depending on the amount present in the mixture. Tungsten Carbide has a higher wear resistance than Tungsten.

Typical cutting speed is of- 30 — mm; when coated it is about — mm. Straight Tungsten Carbide is strong and has a high resistance. Titanium Carbides help in reducing the chip rate of a tool and help in improving the hot hardness.

Because of Ceramics being usually refractory, they can withstand high temperatures of heat, up to oC.

Cutting Tool Materials ~ ME Mechanical

Ceramics are brittle even more than Cast Alloys, which makes them sensitive to thermal shock. Ceramics are costly various cutting tools produce and are sensitive, this renders them usable for only high-quality machinery with a high production rate thus lowering their use.

The cutting edge is formed in the form of the small tip, which is brazed to the shank of lower grade material.

Insert or bit type - A tool bit of high-grade material is formed in the form of polygonal shape, and then it is mechanically various cutting tools by the cutting tool holder.

It avoids rubbing between the edge of the tool and workspace.

It influences the direction of chip flow. Functions of Side Cutting Edge Angle: Increase in side cutting edge angle tends to widen and thin the chip. An excessive side cutting various cutting tools angle redirects feed forces in radial direction which may cause chatter.

Functions of Nose Radius: A sharp point at the end of tool is undesirable, because it is highly stressed, short lived and leaves groove in the path of cut.

Therefore Nose Radius is favourable for long tool life and good surface quality. It affects the tool life, radial force, and surface quality of work piece.

To quantify a cutting edge the following parameters are used: This can also be calculated by the ratio of the two axis of the ellipse. This various cutting tools describes the form of the cutting edge.
