forget about manufacturing method,just tell me is that good surface due to the zebra strip & curvature
is the surface part below good to go for manufacturing??
it is a kitchen water valve head.
due to the zebra strip and curvature,do yo think it can be good to go for manufacturing
consider it as a training part.
my point was the surface quality.is it good due to the zebra strip & curvature?

Parts should be designed to fit their function not designed to fit manufacturing. If you design a part that can not be manufactured either what your trying design can not be manufactured....or you screwed up your design by making the part more complex than it needs to be.
The question here is not "Is this part ready for manufacturing" the question is "Is this part properly designed for it's function" and the latter can not be answered without knowing the function and purpose of the part.
If you're asking "Are these good surfaces"....do they fit the function you want them to?
If you're asking "Can this part be made with any process under any conditions out of any material with any tolerance"....the answer is yes....here.
i want to get smooth surface.as i said its trainning.and i just want to know.is it good in smoothness?

Which of the below surfaces are "Good" in smoothness? The one on the right is a flat plane, the one on the left has a curve. If both are meeting their function and doing so without more complexity than necessary they both have "Good" smoothness.
I can look at your model and say, "Yep, good smoothness". That is relatively meaningless unless we know what you're trying to accomplish.
I don't see any obvious areas on the surfaces that have unusual or not expected bumps. But I have no idea whether the divots, bumps, curves etc are what they are supposed to be or not.
your right,
it is a handle and i want a nice smooth surface in each area the users touch

I don't see any obvious bumps/Edges etc. If you're looking for "No sharp edges" and this is going to be made of metal you will likely end up with a sharp edge along the transitions of one surface to another.
You would need to add a radius along that transition or when released call out that those edges should be broken/Radiused etc.

That's my point. No one can tell you that without having any idea about what the smoothness is supposed to be and what the function is.
Sandpaper will have a very different zebra stripe form than the surface of a telescope mirror. Both have "Good" smoothness for their application.
What material it is made from and how you want to manufacture it are important considerations as well. If it's plastic and going to be injection molded then you need to check the draft on the part. Also, you will have a parting line in the middle of the part. Considerations like this drive how you design the part just as much as how it has to function.
it will made from metal

It's fine.
If you are looking for smoothness here is the guide line.
SOLIDWORKS 2020 Torsion Continuity Relation (G3)
What is it made of, what is the tolerance, is it solid, sheet metal, plastic, how big is it. That would be easy to make if it where a 2" round solid piece of plastic with that form and +/-.05" tolerance. It would be next to impossible to make if it were a 2" sheet metal piece made from 7ga material with +/-.0005".
