cone at lathe machine
(OP)
Hi all, please find attach figure.Its of cone.Material is MS.Till now i have machined round jobs at lathe machines.I am novice in machining.My boss has given me a task of machining this cone on lathe machine having threading at one end (shown red). Raw material will be a rod of MS. Plz tell me the processes involved in machining it.I wll be greatly thankful to you all.
waqas.
waqas.

Am i right?

Just drill and tap the threaded part, set the angle on the cross-feed for the taper, then part off the resulting cone after changing the tool.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

Does your CNC lathe have a barfeed attachment large enough to handle raw material used to make this part?
Depending on your answers the process could be
1. Push the material out.
2. Face end of part.
3. Rough and finish turn taper.
4. Drill hole
5. Bore hole
6. Single point thread
7. Part off.
Otherwise the part will have to be sawed to oversize length.
First CNC Lathe operation
1. Chuck on oversize end of part.
2. Face end of part.
3. Rough and finish turn taper.
4. Drill hole
5. Bore hole
6. Single point thread
Second CNC Lather operation
1. Screw on part to thread.
2. Face off oversize end of part.

The OP did not say he had a CNC lathe, and I agree, with, a CNC the cone would be a lot easier. He also did not say if he had to build more than one part.
The fact is that, if, he can do the operation without un-chucking/re-chucking, he will end up with a more accurate part.
Also if, he can feed through, with the right tool he can part off and face in one operation ready for the next drill and tap operation if needed, if he did have to make more.
If he cannot do that, then he is faced with a part off operation, and a waste piece remaining in the chuck.
