What is significance of rake angle? – Sage-Answer

WebAdvantages of negative rake angle. Stronger tool tip —Larger wedge angle makes the tool tip strong enough to sustain under higher feed and depth of cut. Thus material removal rate (MRR) can be enhanced using such tool without sacrificing tool life. Longer tool life —It takes higher time to worn out a negative rake tool and thus life of ...
