When cutting action takes place due shearing action chip will flow outwards and after some time due to self weight it will fall again because of this wearing takes place at certain distance.

Crater wear take place at rake face of tool.

Crate wear only in brittle material.

Face of the cutting tool at a short distance from the cutting edge only because:
1. Cutting fluid dose not penetrate.
2. Normal stress on rake face is maximum.
3. Temp is maximum.
4. Tool strength strength is minimum.
It can caused by spindle speed is low and a feed rate that is too high in orthogonal cutting this typically occurs.

What is crater wear?

Creater wear means material diffuse from the tool face. It create by friction between surface and chip.

Crater wear occurs only on full facesitting in which cutting tool is quite away at short distance from the hole.

What is a creater wear &why only in brittle materials?

Crater wear is due to the friction between chip and tool rake surface.
I think, In brittle materials, discontinuous chips formed cause this type of wear.

Crater wear is due to diffusion and abrasion and it occurs in ductile materials where continuous chips occur.
