Metal cutting manufacturing process part1
- Metal cutting is a machining process that involves gradually removing excess material from a workpiece in the form of chips using a cutting tool to produce parts to desired dimensions and surface finish.
- There are two types of cutting tools: single-point tools which have a single cutting edge and are used for operations like turning and facing, and multi-point tools which have multiple cutting edges and are used for operations like milling and grinding.
- Orthogonal cutting is a type of metal cutting where the cutting edge of the tool is perpendicular to the direction of tool motion, allowing the forces during cutting to be represented in 2D.

Machining
Single point cutting tools have a shank, cutting part, and various angles that define their geometry. The rake and relief angles affect cutting forces and tool life. Rake angles control cutting forces, while relief angles provide clearance and prevent rubbing. Tool wear occurs through adhesion, abrasion, and diffusion, degrading the cutting edge over time. Tool life is measured by various criteria like cutting time or material removed before failure. Tool life decreases with higher cutting speeds and increases with lower depths of cut and feed rates. Proper selection of tool geometry and cutting conditions can optimize tool life.
CNC Cutting Tools
The one of the major part of CNC Machine is Cutting tools or Inserts. We need to study the Cutting tools and its nomenclature throughly and also study the materials of Cutting tools and types of tools. The Cutting tools are used to remove unwanted materials in the workpiece and to provide a good finish for a customers need.So the Cutting tools is very important to CNC Machine, if there is no cutting tool in CNC Machine, there is no CNC Machine. So the cutting tools are very important to all CNC Machines
