State the working principles of the milling machine?

The working principles of a milling machine are as follows:

1. The milling machine operates on the principle of rotary motion, where a cutting tool rotates against the workpiece to remove material.

2. The cutting tool, typically a rotating cutter, is mounted on a spindle that is driven by a motor. The spindle can move in multiple directions, allowing the cutter to remove material from the workpiece in various ways.

3. The workpiece is securely clamped onto a table or other workholding device, which can be moved in different directions to position the workpiece under the cutting tool.

4. The cutting tool can be moved vertically, horizontally, or at an angle to the workpiece, allowing for precise control over the depth and direction of the cuts.

5. The milling machine can be used to create a wide range of shapes, sizes, and finishes on a variety of materials, including metal, wood, and plastic.

6. The speed and feed rate of the cutting tool can be adjusted to achieve the desired cutting results, such as smooth finishes, precise dimensions, and efficient material removal.
