Principles of chip-breaking
The principles and methods of chip breaking are generally classified as follows :
• Self breaking
This is accomplished without using a separate chip-breaker either as an attachment or an additional geometrical modification of the tool.
• Forced chip breaking by additional tool geometrical features or devices.
Chip breakers are basically of two types :
- After their manufacture – in case of HSS tools like drills, milling cutters, broaches etc and brazed type carbide inserts
- During their manufacture by powder metallurgical process – e.g., throw away type inserts of carbides, ceramics and cermets.
The basic principle of forced chip breaking is schematically shown in Fig. when the strain hardened and brittle running chip strikes the heel, the cantilever chip gets forcibly bent and then breaks.
- Clamped type chip-breaker
Fig. schematically shows three such chip breakers of common use :
