Hello, everyone.
using the thread function, it creates the threaded part and up here no problem. but the final of the same ends flat.
in reality threads tend to "go out" how can it be done?

I have seen that many suggest extrusion to cut.

thanks in advance

make a cut sweep of the trapezoidal section along a rake at 45°.

ok, but with zw3d it is even easier

if he asks for solidworks why talk about another software?
You make it laugh

 

[Polymar]

because I knew you would respond in this way btw in recent times I am also doing a pile of threads especially gas npt, not on the lathe, but precisely with swx on plastic details that have to finish in mold cmq when you have the mechanical notions, the cad speech and how to do it pass second place, no?! !

thanks polymar, and thanks massivonweize,
I will apply polymar's suggestion as the video posted honestly does not give for nothing the realistic effect of the tool output during threading on lathe (in my case mobile fan).

thanks for the help

there is also another link that however with 2014 I can not check

the most correct method is to have the cylindrical propeller for the thread with sweep and a second successive conical propeller with increasing diameter, just as it does at the lathe, so the sweep dies to zero gradually.

Are you absolutely right, in inventor there the variable helical function, to do what you suggested you also exist in solidworks or do I have to do two separate sketches?

@mammals : However, from my point of view, no advice is useless, the forum should also be understood as a sharing of ideas and advice.

Considering the costs and sales of cad/cam products with everything that follows at the license level (=$$$), it is logical that companies send in trade fairs in the hope of detaching some extra sales contract. The time has come when you could have contact with real technicians with solid skills.

worth noting that what you asked, it is part of one of those small but great details that distinguish a fake technician from a

you don't have to do two sketches, but two spiral/elica wireframes, and for a pure operational convenience run two features doesn't take you away so much longer, indeed you will have a better control of the entire thread. If you want to turn 1 ms, do the ctrlc+ctrlv of the sweep and then change the angle

the variable propeller there is but you have to look how it works correctly with the solidworks guide. I believe however that you will have to do thread with two sketches (sagoma + sweep/elica path) and then do the second function with the copied template on the new plane and the sweep/elica path.
