Cutting Tool

• Definition: A device or object used to remove material from a workpiece by shearing or cutting to achieve a desired shape or size.

Types of Cutting Tools

• Single Point Cutting Tool: Has one cutting edge, used for turning, facing, and boring operations, such as turning tool, facing tool, and boring tool.
• Multi-Point Cutting Tool: Has multiple cutting edges, used for milling, drilling, and grinding operations, such as milling cutter, drill bit, and grinding wheel.

Characteristics of Cutting Tools

• Hardness: Ability to resist wear and tear.
• Toughness: Ability to resist breakage.
• Wear Resistance: Ability to resist wear and tear.
• Cutting Edge Angle: Angle between the cutting edge and the workpiece, affecting cutting forces and tool life.
• Rake Angle: Angle between the cutting edge and the direction of cutting, affecting cutting forces and chip formation.

Cutting Tool Materials

• High-Speed Steel (HSS): Most common material, durable and versatile.
• Cemented Carbide: Hard and wear-resistant, used for high-precision cutting.
• Ceramic: Hard and brittle, used for high-speed cutting.
• Diamond: Extremely hard, used for cutting hard materials.

Cutting Tool Geometry

• Cutting Edge Angle: Affects cutting forces and tool life.
• Rake Angle: Affects cutting forces and chip formation.
• Clearance Angle: Affects tool life and cutting performance.
• Nose Radius: Affects cutting forces and tool life.
