Turning (from Chapters 1 to 5)

1. In terms of turning, what is the difference between cutting depth and cutting feed?
   1. The cutting depth is a measure of how much the tool is plunging inside the stock and it is measured in millimeters (mm), while the cutting feed is a measure of how much the tool is advancing at every revolution, and therefore it is measured in mm per revolution (mm/rev).
   2. The cutting depth is how deep the tool is cutting, measuring its position from the rotation axis of the chuck, while the cutting feed is a measure of how fast a tool is plunging radially into the stock.
   3. The depth of cut is a measure of how much the cutting edge is engaged into the stock, while the cutting feed is the tangential velocity measured at the tooltip.
2. What is ?
   1. specifies the cutting power needed to cut a certain material, therefore it is measured in kilowatts (kW).
   2. is the specific cutting force, measured in Megapascal (MPa), and is a value representing how easily a certain...
