Q. How does the milling machine cuts its workpiece?
A milling machine works like a drill machine. Instead of drilling a hole, it rotates the mill to shape an object thus there are 2 types of milling methods.Horizontal and vertical for flexibility.The spindle can be shortened and extend and the table can be raised or lowered.

Types of milling.....
Climb milling:
Each tooth engages the material at a definite point, and the width of the cut starts at the maximum and decreases to zero. The chips are disposed behind the cutter, leading to easier swarf removal. The tooth does not rub on the material, and so tool life may be longer. However, climb milling can apply larger loads to the machine, and so is not recommended for older milling machines, or machines which are not in good condition. This type of milling is used predominantly on mills with a backlash eliminator.
