 If a cutting tool is designated as 0° - 10° - 6° - 6° - 8° - 75° - 1 inch, what is the side cutting edge angle of the tool

 If a cutting tool is designated as 0° - 10° - 6° - 6° - 8° - 75° - 1 inch, what is the side cutting edge angle of the tool Correct Answer 75°

Explanation:

Tool designation or tool signature under ASA (American Standards Association) system is given in this order:

Back rake angle (αb) – Side rake angle (αs) – End relief angle (γe) – Side relief angle (γs) – End cutting edge angle (Ce) – Side cutting edge angle (Cs) – Nose radius (R) inch

αb – αs – γe – γs – Ce – Cs – R

Additional Information

Orthogonal Rake System (ORS): 

i (inclination angle) - αn (Normal rake angle) - Side relief angle - end relief angle, end cutting edge angle - approach angle - nose radius (r) mm.

Consider the following statements: 1. HSS tools wear very rapidly, whereas in cemented carbide tools, even though hardness is retained, crater wear can occur due to solid-state diffusion. 2. Cutting tools made of Super-HSS, also known as cobalt-based HSS, are made by adding 2% to 15% of cobalt which increases the cutting efficiency at heavier cuts by increasing the hot hardness and wear resistance. 3. Tools failure due to excessive stress can be minimized by providing small or negative rake angles on brittle tool materials, protecting tool tip by providing large side-cutting edge angles, and honing a narrow chamfer along the cutting edge. Which of the above statements are correct?
