What is shoulder turning operation?

Turning to a Shoulder When turning more than one diameter on a workpiece. The change in diameter or step, is known as shoulder.

What is grooving operation?

Grooving or recessing operations, sometimes also called necking operations, are often done on workpiece shoulders to ensure the correct fit for mating parts. Grooving the workpiece prior to cylindrical grinding operations allows the grinding wheel to completely grind the workpiece without touching the shoulder.

What is difference between machine and machine tools?

The term Machine includes wide variety of machinery, whereas Machine Tools are all such machines that possess the following characteristics. Machine Tools must be power driven (human operated machines are not machine tools). Machine Tools must be non-portable (portability is irrespective of size).

What are different types of turning operation?

Common types of turning operations include the following:

• Face Turning.
• O.D. Turning.
• I.D. Turning.
• (Boring)
• Grooving and.
• Profiling.
• Threading.

What is reaming operation?

Reaming is a finishing operation of high-precision holes performed with a multi-edge tool. High surface finish, superb hole quality and close dimensional tolerance are achieved at high penetration rates and small depths of cut.

Which tool is used for grooving operation?

Grooving tool usually is a carbide insert mounted in a tool holder, can be used to cut external or internal grooves, and many other machining operations. There are multiple designs of grooving inserts, like a single tip or several tips for different configurations.

Who is father of machine?

What does shoulder turning on a lathe mean?

Shoulder Turning: When a workpiece has different diameters and is to be turned, the surface forming steps from one diameter to the other is called the shoulder, and machining this part of the workpiece is called shoulder turning.

Which is an operation performed by a lathe attachment?

(c) Operations which are performed by using special lathe attachments are: 1 Milling – The milling machine lathe attachment is attachable to an existing milling machine to eliminate the need for an operator owning both a milling machine and a lathe. 2 Grinding – 3 Slotting –

How are jobs held on a lathe machine?

LATHE OPERATIONS 1 Job is held and driven by chuck with the other end supported on the tailstock center. 2 Job is held between centers and driven by carriers and catch plates. 3 Job is held on a mandrel, which is supported between centers and driven by carriers and catch plates. 4 Job is held and driven by a chuck or a faceplate or an angle plate.

How is the operation of a lathe similar to external turning?

The operation is similar to external turning in that the feed and depth of cut are given by the longitudinal and cross-motions of the tool respectively. Since the enlarged hole is being generated with a motion of the workpiece about an axial motion of the tool.
