Single Point Cutting Tool Vs. Multi Point Cutting Tools [PDF]

Contents

In this article, I shall explain to you the difference between Single Point Cutting Tool Vs. Multi Point Cutting Tool. I have also provided a PDF for the same.

What is Single Point Cutting tool

A Single Point Cutting Tool is a vital instrument in machining, featuring a sharpened point and a shank. These tools, categorized into Single Point and Multi-Point types, can be made from materials like high-carbon steel, high-speed steel, ceramics, and diamonds.

In terms of geometry, we explore components like the shank, flank, face, heel, nose, nose radius, and cutting edges, along with critical angles such as side cutting edge angle and end cutting edge angle. Single Point Tools bring versatility, precision, and cost-effectiveness, with advantages like reduced tool wear, improved surface finish, and lower cutting forces.

However, they come with limitations such as higher tool wear rates and shorter tool life compared to alternatives. Widely used in processes like turning, facing, boring, and threading on lathe machines, these tools play a key role in machining operations.

What is Multi Point Cutting Tool

A Multi Point Cutting Tool is a versatile instrument with several sharp cutting edges that efficiently remove material from a workpiece through rotational motion along horizontal or vertical axes. These tools, including milling cutters, circular saws, grinding wheels, knurling tools, hobs, broaches, and reamers, offer flexibility for various machining operations.

Unlike Single Point Cutting Tools, Multi Point Tools usually involve the rotation of the tool while the workpiece remains stationary. They bring advantages such as high productivity, extended tool life, cooling effects, lower cutting forces, and precision. However, they come with drawbacks like vibrations, noise, complexity, endurance challenges, limited applications, and critical design considerations.

In essence, Multi-Point Cutting Tools are dynamic tools that play a crucial role in machining, offering a balance of efficiency and considerations for their application.
