In a single point turning tool, the side rake angle and orthogonal rake angle are equal. ϕ is the principal cutting edge angle and its range is 00<900. The chip flows in the orthogonal plane. The value of ϕ is closest to |
| A. | 00 |
| B. | 450 |
| C. | 600 |
| D. | 900Answer: dExplanation: Interconversion between ASA (American Standards Association) system and ORS (Orthogonal Rake System) tanαs = sinφtanα − cosφtaniwhere αs = Side rake angle α = orthogonal rake angle φ = principle cutting edge angle = 00<900 i = inclination angle (i = 0 for ORS) αs = α (Given) tanαs =sinφtanα − cosφtan(00) tanαs = sinφtanα tanαs/tanα = sinφ |
