Question

In a single point turning tool, the side rake angle and orthogonal rake angle are equal. $\varphi$ is the principal cutting edge angle and its range is $0^o\le \varphi \le {90}^o$. The chip flows in the orthogonal plane. The value of $\varphi$ is closest to

• A. $0^o$
• B. ${45}^o$
• C. ${60}^o$
• D. ${90}^o$

Answer 1

The correct option is D ${90}^o$
