What is negative relief angle? I think it must be negative rake angle and is provided while machining high strength alloys.

Relief angle can't be zero or negative, so here should be negative rake angle which is used for hard and brittle materials.

Not relief angle, it is a negitive rack angle.

Relief angles are to avoid the tool rubbing from work piece.

The answer should be rake angle.

- It makes the tool blunter, increasing the strength of the cutting edge.

What purpose used to negative rake angles?

I think this angles used to machining the hard materials only.

Dinesh said:   9 years ago
Negative rake only used for hard metals. But negative relief angle used for soft metals.

Negative rake angle never exists it varies from 5 to 15.

Adarsh said:   10 years ago
Relief angle never negative. It lie between 3-15 degree.

MUKESH YADAV said:   6 years ago
Relief angle couldt negative it lies 3 to 15 degree.
