I think -ve rake angle is given for machining of high strength materials. And -ve relief angle does not even make sense. Does -ve relief angle even exists?

It must be negative rack angle.

Not relief angle, it is a negitive rack angle.
Relief angles are to avoid the tool rubbing from work piece.

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

Relief Angle can not be negative. It is always positive in any condition to minimise rubbing between flank and work surface.

The negative insert has an angle of 90° (0° clearance angle), while a positive insert has an angle of less than 90° (for example, 7° clearance angle).

Relief angle is always positive.

Explain the concept of negative relief angle.

What in the world is a negative relief angle?
Does it mean the tool will interfere in to the workpiece? I don't think negative relief is possible. Also, if they are talking about rake angle then why would soft workpiece require negative rake? If it is a rake. Then please someone explains the concept of negative rake on soft materials.

Relief angle couldt negative it lies 3 to 15 degree.
