A continuous type of chip is quite troublesome, they should be broken into comparatively small pieces for the ease of handling and to prevent it from becoming a work hazard, hence chip breakers are used to reduce the swarf into small pieces as they are formed.

Function of Chip-Breaker in Cutting Tools
In mechanical engineering, a chip-breaker is an essential feature of cutting tools, designed to improve the machining process. Its main function is to control the shape and size of the chips produced during cutting operations.
Importance of Short Chips
- Enhanced Control: Shorter chips are easier to manage and can prevent issues such as entanglement or clogging.
- Improved Surface Finish: By breaking chips into smaller segments, the cutting tool can maintain a consistent engagement with the workpiece, resulting in a better surface finish.
- Increased Tool Life: Controlling chip size helps to reduce the wear on the cutting tool, extending its operational lifespan.
How Chip-Breakers Work
- Geometric Design: The chip-breaker has a specific geometry that induces stress in the chip, causing it to break at predetermined points.
- Angle and Positioning: Proper angle and positioning of the chip-breaker relative to the cutting edge are crucial for effective chip segmentation.
- Material Considerations: The material and coating of the chip-breaker can also influence its effectiveness in breaking chips efficiently.
Conclusion
In summary, the primary function of a chip-breaker is to break the chips into short segments, enhancing control over the machining process, improving surface finish, and extending tool life. Understanding the role of chip-breakers is crucial for optimizing cutting operations in mechanical engineering.
