1) Lip angle
2) Clearance angle
3) Rake angle
4) Cutting angle

Answer 1

The only Angel on which the strength of the tool depends is Rake angle.......

Answer 2

Answer:

The only angle on which the strength of the tool depends is the rake angle.

Explanation:

• Rake angle is a type of angle formed between the cutting face of a tool and the line that is “perpendicular to the work piece”.
• It refers to the cutting edge angle which affects the chip disposal, cutting resistance and temperature and the tool life.
• Increased or positive rake angle will increase the sharpness of the tool and lowers the strength of cutting edge.
• Decreased or negative rake angle will decrease the cutting power of the tool but increases cutting resistance.
• Hence the rake angle should be appropriately adjusted according to the type of work piece.
