16.3.1. MC: Cutting Mechanism
The sine in the denominator of the generic cutting force equation has 4 angles in the argument. What happens if the sum of these 4 angles approaches 180 degrees?
The bold green answers are true.

The cutting forces become very high.

The cutting forces become negative.

Nature will choose another cutting mechanism.

The cutting force will be constant above a certain sum of the 4 angles.

The cutting process will be cavitating.

The adhesion will become zero.

The vertical cutting force will become negative.

The curling type will occur.
16.3.2. MC: The Snow Plough
Which of the following statements is true?
The bold green answers are true.

The snow plough effect occurs when the sum of the 4 angles in the argument of the sine in the denominator of the generic cutting equation is larger than 180 degrees.

The snow plough effect occurs when the sum of the 4 angles in the argument of the sine in the denominator of the generic cutting equation is equal to 180 degrees.

The snow plough effect will occur when the angle between the cutting velocity and the blade is not 90 degrees.

The snow plough effect will occur when the angle between the cutting velocity and the blade edge is smaller than 90 degrees.

The snow plough effect will occur when the angle between the cutting velocity and the blade edge is larger than 90 degrees.

The snow plough effect will push the blade sideways.

The snow plough effect reduces the cutting forces strongly.

The snow plough effect increases the cutting forces strongly.
