1. Increasing the strength of the cutting edge
2. Avoiding rubbing action with the finished surfaces
3. Reducing the magnitude of the cutting force
4. Better heat dissipation
Reducing the magnitude of the cutting force
1. Decreases by 50%
2. Increases by 300%
3. Increases by100%
4. Remain unaffected
Increases by100\%
1. removes the heat faster from the cutting zone
2. forms a coating on the cutting tool by chemical reaction
3. forms a low shear strength film of work material at the tool chill interface
4. Serves as a dielectric, minimizing there by reactions due to EMF at the interface
removes the heat faster from the cutting zone
1. very high speed
2. large uncut chip thickness
3. use of cutting fluid
4. increase in positive rake angle
large uncut chip thickness
1. cutting fluid does not penetrate
2. Chip tool interface temp is maximum
3. normal stress on rake face is maximum
4. tool strength is minimum
Chip tool interface temp is maximum
1. Moving chip
2. Cutting tool
3. Work material
4. Machine tool
Moving chip
1. Sliding model of friction
2. Sticking and then sliding friction model
3. sticking friction model
