There are three types of chips that are commonly produced in cutting,
A discontinuous chip comes off as small chunks or particles. When we get this chip it may indicate,
A continuous chip looks like a long ribbon with a smooth shining surface. This chip type may indicate,
Continuous chips with a built up edge still look like a long ribbon, but the surface is no longer smooth and shining. This type of chip tends to indicate,
- high friction between work and tool causes high temperatures that will occasionally weld the chip to the tool. This will break free, but the effects is a rough cutting action.
Continuous chips, and subsequently continuous cutting action is generally desired.
