Why Is Facing Operation Done?

What is the operation of facing?

Facing is the process of removing metal from the end of a workpiece to produce a flat surface.

Most often, the workpiece is cylindrical, but using a 4-jaw chuck you can face rectangular or odd-shaped work to form cubes and other non-cylindrical shapes..

Why is facing needed?

Facing is machining the ends and shoulders of a piece of stock smooth. flat, and perpendicular to the lathe axis. Facing is used to cut work to the desired length and to produce a surface from which accurate measurements may be taken.

What is the process of turning?

Turning is a form of machining, a material removal process, which is used to create rotational parts by cutting away unwanted material. The turning process requires a turning machine or lathe, workpiece, fixture, and cutting tool.

What is turning and facing?

Facing vs Turning: Are They They Same? Turning is a catch-all term used to describe any machining operation in which a stationary cutting tool is pressed against a rotating workpiece to remove material from the workpiece. As a result, lathe facing is a type of turning operation.

What is chamfering operation?

fər/ is a transitional edge between two faces of an object. This term is commonly used in manufacturing and mechanical engineering. … Chamfering the edges of a metal bar removes the burr from the end of the bar. De-burring removes metal and imperfections that can interfere with the function of a part.

What is the thickness of chamfering?

Chamfering is fast and above all cost-effective with our welding edge former (nibbler). This machine can be set continuously in any chamfer angle between 20° – 45°. Depending on the strength of the material the sheet or plate metal thickness is up to 15 mm with a strength of 400 N/mm².

Why chamfer is used?

Machinists use chamfers to “ease” otherwise sharp edges, both for safety and to prevent damage to the edges. A “chamfer” may sometimes be regarded as a type of “bevel”, and the terms are often used interchangeably. … Chamfers may be formed in either inside or outside adjoining faces of an object or room.

What is difference between milling and turning?

In turning, the component is positioned in a chuck and rotated at speed while the cutting tool is traversed to the workpiece. Milling works in reverse – with the workpiece remaining stationary while the milling table/fixture moves and the cutters rotate.

How many types of turns are there?

Few specific turning operations, such as tapered turning, spherical generation, hard turning, facing, parting and grooving, will be explained below. Taper turning means, to produce a conical surface by gradual reduction or increase in diameter from a cylindrical work piece.

Which type of feed is needed in facing operation?

cross feedWhich type of feed is needed in facing operation? Explanation: Facing operation is done by the cross feed. In facing, workpiece is rotated against the single point cutting tool.

What is a facing tool used for?

Facing on the lathe uses a facing tool to cut a flat surface perpendicular to the work piece’s rotational axis. A facing tool is mounted into a tool holder that rests on the carriage of the lathe. The tool will then feed perpendicularly across the part’s rotational axis as it spins in the jaws of the chuck.

How is chamfering done?

Chamfering: Chamfering removes the burrs and sharp edges, and thus makes the handling safe. Chamfering can be done by a form tool having angle equal to chamfer which is generally kept at 45°.

Which machine is used for face milling operation?

Face milling is the most common milling operation and can be performed using a wide range of different tools. Cutters with a 45º entering angle are most frequently used, but round insert cutters, square shoulder cutters and side and face mills are also used for certain conditions.

What is the meaning of facing?
