Metric 3d threads

[bestali]

I couldn't find your sweep path in the dwg file? When doing 3d you should always have delobj set to zero so that your originating geometry is preserved.

I always put this stuff on a hidden layer in case I need it later. In this case I cannot analyze where you went wrong without the profile and path. I have no motivation to create the geometry myself since I know you had it and did not attach it here.

hi Sir JD Mather,

i m new here, i have read your threads, very informative sir i want to learn more about making 3d thread,for this i need your help.. Plz could give me "dwg" file "Tutorial 4" ?

We don't give away dwg files here. That's not how this forum works. The tutorial is there for you to work through and create the threads yourself. If you're having problems or if you don't understand how to do something, post questions. You will learn nothing by simply having someone hand you a finished drawing file.

ok.

 

i m having problem with making 3d screw " Nut 15 x Dia 25 , tapped M8 x 1.5 " i can't understand what it says...

 

Nut 15? Dia 25 ?

 

tapped M8 x 1.5 ?

 

plz any one help me to solve this mystery ??

i need step by step help for making 3d nuts and bolts .

The absolute number one most important thing to do before starting any 3D project is to do your research. Find reference images, gather technical data and understand fully what it is you are going to create.

 

Do you know anything about metric nuts and bolts? Have you done any research on your own?

 

M8 x 1.5 is a metric thread designation. The M8 refers to the major diameter of the thread, (8mm), and 1.5 is the thread pitch, (distance between each thread). This means there is a thread every 1.5mm.

 

I have no idea what's going on with that nut though? The drawing makes no sense. The plan view and the section view look completely different. Almost as if they are two different parts?

 

 

FYI: In the future, please start a new thread when you have a question. Don't stick your question on to the end of someone else's thread. I have moved your question to its own thread.

OK thanks sir.

 

yeah i do research on metric threads but can't find enough info,on the other hand wht you told me will helps me a lot. thanks.

 

yeah those r two different parts.

Nut looks like one part to me - missing dimensions tho?

 

And 1.5 is not a standard pitch for an M8.

Yeah, I'm looking at it with a fresh set of eyes now. It wasn't making sense at 6:30 this morning.

 

And 1.5 is not a standard pitch for an M8.

 

Yes, I know. I didn't say it was a standard pitch for M8. I said the 1.5 represents the thread pitch, regardless of whether it's standard or not. Maybe the OP is making a non-standard M8 thread?

[JD Mather]

Or this. (I would always dimension across flats - not width of a flat on a cylnder. Go out to the shop floor and try to hold dimension on flat width. Doesn't relate to wrench size anyhow. 12mm might be small for this nut, in either case the dimensions don't match the image.)

thanks sir "JD mather" and "CAD 64"

 

u have solved my problem.

i was also in trouble , whether those r two different parts or one.

but this picture clears it .

thanks a lot.

Hi bestali,

To complete the subject for indeed to explain by my eminent colleagues

this below the ISO metric screw thread drawing

And link which helps you to understand the metric system.

I just found it, Its look like a part of collet chuck

thanks sir. now i can understand the metric thread system.
