Turning pass count

Calculates simple turning time from travel length and feed rate.

Calculates turning material removal rate from diameter, depth of cut, feed per revolution, and spindle speed.

Calculates cutting force from cutting power and cutting speed in a simplified model.

Calculates material volume removed in turning from diameter difference and cut length.

Calculates turning time from cut length, approach length, and feed rate.

Calculates the minimum pass count from total depth and depth per pass.
