Expert Solution & Answer

To determine

Describe the types of machining operations that can be performed on a lathe.

Explanation of Solution

Lathe machines are highly adaptable and have the capacity to perform numerous machining operations which produce a borad variety of shapes, for example:-

1. Turning: In order to have curved, conical, straight, or grooved workpieces like spindles, shafts, and pins.

2. Facing: In order to produce a flat surface at the end of the part and perpendicular to its axis parts which is assembled with different components? Not to forget face grooving for theapplications as O-ring seats.

3. Cutting with form tools: In order tocreate different axisymmetric shapes for functional purposeor simply for aesthetics.

4. Boring: In order to widen cylindrical cavities or a hole created by anearlier process or to creategroovesthat are circular and are internal.

5. Drilling: In order to produce a holeso asto be followed by boring it for enhancing its dimensional precision as well as its surface finish.

6. Parting: It is known as cutting off as well. This is utilized in order to extract a piece out from the end of a part. The same is done for the manufacturing of slugs or maybe blanks for added processing into discrete products.

7. Threading: In order to create threads that are internalor external.

8 .Knurling: In order to make regular shaped roughness on the cylindrical surfaces, as is the case in producing knobs and handles.
