Torque or the moment arm is quantified by taking the cross product of the force perpendicular to the axis of rotation and the position vector, taking the dot product of these gives us the SI units of Nm To get the magnitude of torque it is also important to take into consideration the angle theta between the force vector and the position vector

The milling process – definitions Cutting speed,v c Indicates the surface speed at which the cutting edge machines the workpiece Effective or true cutting speed, v e Indicates the surface speed at the effective diameter (DC ap)This value is necessary for determining the true cutting data at the actual depth of cut (a p)This is a particularly important value when using round insert cutters
