Drawing for multiple slots

Anonymous — Mon, 20 Jun 2016 16:33:59 GMT

Hi, I have a question about showing dimension on the drawing for slots.

I found a website -> http://www.fcsuper.com/swblog/?p=206

which shows me how to do a correct dimensioning in 3 different ways for a single slot.

But I just don't know how to call out for multiple slots.

FYI, there is an other identical circle-like curved slots on the other side, that's that 4x means and 2x is for each slot.

Thanks for helping.

Your question isn't clear to me, but assuming there are other identical features on the part - you only need to dimension the feature size once and then only dimension the feature position (center point location) for the other instances.

what's your companies/employers drafting standards say ...

I've seen 4x and 4 Places ...

just curious if I can do the 4x 2x R. Because usually there is only 2x R .
Even they are symmetrical, I still need to how the dimension?
Thanks !

Its just a school project, I am wondering if there is any standard thing that I should follow.

I would ask your instructor ...

While I would understand how you'd call out the radius twice ...you don't have a width of the slot due to the curve.

You could also call out the radius for the inside and outside for the slot... and then the 2x

as for the 4x 2x r.17

maybe

2x R.17 (4 places)

My preference would be to leave out especially the 4x and I see no reason for the 2x either.

It would depend on the punch used. ( and the standards that your drafting to; ANSI, ISO, etc)

If the punch has both sides (two curved slots) then its simply 4x.

If its an individual punch the correct method would be to put 8x (since they would need to position the punch 8 times.)

(This is the most common I have seen on a shop floor for ANSI)

That said I'm sure there are many ways it could be dimensioned.

I hope this helps,
