Negative Rake Angle:
Negative Rake Angle: Negative rake angle is the cutting angle together with it takes a crucial business office at the machining process. We explained clearly most amount geometry of unmarried betoken cutting tool before. the primary forcefulness of the cutting tool depends on the rake angle, hither nosotros larn the betoken why rake angle plays a major purpose inwards the cutting process. Especially Negative rake angle generally reckon field cutting hard, tough together with potent metals like Aluminium oxide, silicon carbide etc..
While cutting tough together with potent materials oestrus generated is high, together with therefore the cutting tool should hold the required negative rake angle to resist shocks together with temperature at that stage. at that topographic point is also a high possibility inwards producing high friction rate, Tool wear, surface roughness, imperfections etc. To minimize all these factors negative rake angle takes a crucial business office inwards the machining difficult together with tough materials. When nosotros follow the required cutting angles nosotros tin overtake to a greater extent than or less disadvantages similar Wear, friction, temperature, tool life etc.
Advantages of negative rake angle:
- There is a direct chances to increment inwards tool life.
- Smooth surface tin hold upwardly obtained.
- Cutting speed tin hold upwardly increased.
- Cutting tool forcefulness tin hold upwardly increased.
- Imperfections are eliminated.
- Depth of cutting tin hold upwardly increased past times maintaining a required rake angle.
