The side relief angle in a cutting tool signature of 10, 20, 7, 6, 8, 15, 2 is
- A. 10
- B. 7
- C. 6
- D. 8
Answer: C. 6
Explanation: In the ASA (American Standards Association) tool signature system, the sequence is: Back Rake Angle, Side Rake Angle, End Relief Angle, Side Relief Angle, End Cutting Edge Angle, Side Cutting Edge Angle, and Nose Radius. The sequence given is 10, 20, 7, 6, 8, 15, 2. The fourth term is 6, which corresponds to the side relief angle.
