Questions & Answers

Q: What are the different systems of nomenclature for tool angles discussed in the video?

The video discusses Maximum Rake Angle (MRS), Orthogonal Rake Angle (ORS), and Normal Rake Angle (NRS) as the three different systems of nomenclature for tool angles.

Q: What is the disadvantage of the Maximum Rake Angle (MRS) system?

The MRS system cannot directly measure certain angles, but they can be obtained by converting the angles measured in the ORS and NRS systems.

Q: How can the interrelation between the different systems of nomenclature be established?

The interrelation between the systems can be established by using formulas and equations that relate the angles measured in one system to the angles required in another system.

Q: What are some key angles and measurements discussed in the video?

The video discusses back rake angle, side rake angle, inclination angle, orthogonal rake angle, side clearance angle, end clearance angle, normal clearance angle, and normal rake angle.
