Depth Of Cut: The depth of cut is determined by the width of the chip. During the roughing operation, the depth of cut is usually much more greater than that of the finishing operation.. For turning, it is one-half the difference between the inner and the outer diameters of the workpiece.

Geometric Transformations: In order to manipulate a modeling object in the space, geometric transformations are used. There are two kinds of geometric transformation, that of transforming the object and transforming the coordinate system. First one moves the object within the existing coordinate frame, such as moving the primitives in solid modelling. Second one moves the coordinate system, and then the object is viewed from the new coordinate frame such as finding a better view or doing a 2-D orthogonal projection. The transformation methods are the same for both cases, except the signs are changed.

Resolution: Resolution is also called sensivity. It is the smallest increment of motion of the machine components.

Push System: In traditional manufacturing, the parts are made in batches, placed in inventory, and used whenever necessary. This approach is known as a push system, meaning that parts are made according to a schedule and are placed in inventory to be used whenever they are needed.
