6. What are the limitations of a milling machine?

Answer:

The major limitations of a milling machine are as follows:

  1. Milling machine is mostly used for machining jobs of smaller size
  2. Its speed is slow for machining long jobs
  3. Cutting tool is costlier

7. Name two milling methods:

Answer:

  1. Conventional milling (Up Milling)
  2. Climb milling (Down Milling)

8. Define conventional milling

Answer:

In conventional milling, the cutting tool rotates in the opposite direction to the movement of table. In the conventional or up milling, the chip starts at zero thickness gradually increases to the maximum size.

9. Define Climb milling

Answer:

When the feed motion is in the same direction as that of motion of the cutter, the milling is known as climb milling or down milling. In climb milling, the chip starts at maximum thickness and goes to zero thickness gradually.

10. Define milling cutter.

Answer:

A hardened steel disc or cylinder on which the cutting teeth are arranged either on its periphery or on its end or on both is called milling cutter. Usually the cutter is held in a fixed, but rotating position and the work-piece passes the cutter during the machining operation.

11. Name the materials used for milling cutters.

Answer:

Milling cutters are generally made of high speed steel or sintered carbides.

12. What is plain milling cutter?

Answer:

It is also called slab milling cutter and is basically cylindrical with the cutting teeth on its periphery. It is generally used for machining flat surfaces.

13. What is a side milling cutter?

Answer:

This cutter is similar to plain milling cutter except that is has teeth on its sides also. These cutters may have straight, spiral or staggered teeth. Further these may be solid, inserted blade or tipped construction and may be profile sharpened or form relieved.

14. What is the use of metal slitting saw cutter?

Answer:

It is used for cutting deep slots and parting off materials into pieces.

15. Define angle milling cutter.

Answer:

Any milling cutter which has cutting teeth at an angle to the axis of rotation is known as angle milling cutter.

    Nice and helpful questions of milling machines

  8. Victoria Addington

    You made a good point when you discussed that the milling machine is mainly used for smaller-size machining tasks. My friend told me that their projects require the use of a milling machine. He is even looking for a milling machine shop that can provide the right unit for their project.
