Anyone drawing actual thread pitches?

[Anonymous]

Hello,

We are working on a very precise assembly that we need to see actual thread
pitches on shafts and mating holes.

We have run into a problem with this. If we do 1-10 pitches of a thead
profile, IV is fine. We need to run about 400 pitches on a long rod, and we
have not been able to accomplish this, or rather, we "end task" thru windows
manager to stop IV from working. The longest we have let a machine crunch
is 50 minutes.

We have duplicated this on 2 different machines, a laptop and a desktop,
both equipped very similarly, and have had the same results, so we don't
feel it is a hardware glitch.

Has anyone else run across a similar problem, or have a solution for this?
By the way we are running IV8.

Thanks,

Bill

Did you try arraying a small "easy" pitch of thread?

We have been using the "coil" command to do this. We build the profile of
the thread, and then revolve it with the coil command. we have done bolts
as small as about an 8-32 over 1/2 inch in length (takes about a minute to
finish), and the largest, which we've never let run to completion - 3/4 Dia
Acme thread over about 24"

The steps we use are as follows:

1- create a shaft
2- build the thread profile
3- Align the shaft and thread profile properly, and apply the coil command
4- wait
5- finish or crash

In running MD in the past, I used to "work around" this by creating
"representational" threads, but I was hoping IV had enough horsepower to
give me the real thing.

Thanks again,

Bill

Sounds good, Bill.

Now, try a small section of thread and array it to see if you can get
something you can work with (a minute or 2 for creation)

thanks...we'll give it a shot. In the past we have tried working our way up
to the desired thread pitches. It seems to really bog down after 100
pitches.

Even further back circa MDT3 there was a ?14? rev limit where the helix
would wack itself.

I would think a 100 rev helix would be quite massive regardless.

Using the coil command will produce VERY POOR performance.
