Cutting Speed

It is the distance travelled by a point on the cutting edge of the milling cutter to remove metal in time duration of one minute. It is expressed in meters per minute.

The cutting speed depends upon the material to be machined, the cutter material, depth of cut, feed, type of operation and the coolant used.

Feed

The feed in a milling machine is defined as the distance the workpiece advances under the cutter. Feed can be expressed in three different methods:

  1. Feed per tooth: It is the distance the work advances in the time between engagements by the two successive It is expressed in mm per tooth.
  2. Feed per cutter revolution: It is the distance the work advances in the time when the cutter turns through one complete It is expressed in mm per revolution of the cutter.
  3. Feed per minute: It is the distance the work advances in one It is expressed in mm per minute.
Advantages and Disadvantages of Milling Machine

The feed in a milling machine depends on the material to be machined, cutter material, depth of cut, cutting speed, type of operation and the rigidity of the machine.

Depth of Cut

The depth of cut is the thickness of the material removed in one pass of the work below the cutter. It is expressed in mm.
