How could I post an iges file here for some opinions on how I could fixture a particular part?

If you post a picture as a jpg I can look at it. I don't have the faintest idea how to open an iges file.

Sorry Geof all I have is an iges file and he wants me to quote on it. I can view it as a wire frame and check dims. in my EZCAM software. It's actually a ".igs" extension. Maybe tomorrow I can save it as a dxf file and send it . I dont have my software key here with me tonight.


Thanks

:confused: Ok I've saved the file as a dxf. If any one has an idea on how I could hold this part to machine it please let me know.

My computer tells me this is an Autocad file and I do not have Autocad so I cannot open it. I think you should be able to save it as a .jpg

I saved the file as a jpg but when I try to open the jpg file it says no preview available, but I'll attach the file anyway and we'll see what happens.

nope , guess it didn't work.
oh well thanks anyway for your time.

Oh, do you use cam software? It seems that most all cam can import a dxf file.

Thanks again

...Oh, do you use cam software?...

I do not, much too old and stuck in my ways to learn something new :) .

I'heard that. I'll bet you could figure this out though if you could see it. I've seen your posts and I know you've been around awhile.

Thanks anyway and much respect.:cheers:

:banana: Ok guess what? I've saved it as a jpg.

Lets see if this will work.

Can you drill and tap the back? Bolt it to a tombstone??

Don't know yet but I would assume so but I am afraid of the flange flopping around a bit, it is only 3/16" thick.

What chu think?

stebanski,

I just received the Mitee Bite catalog today, and they sure like they may have a solution for you. Check 'em out.

The flange may be only 3/16 but it has the ridge running down the center and this would give stiffness.

Scaling from the flange in your sketch it looks like the holes are around 1/4" to 5/16" and they seem to have a reasonable chamfer or small countersink on top.

Also scaling from the flange he maximum thickness would be about 1/2" to 5/8" and the width around 2".

You don't show a bottom view so I am going to assume it is flat.

I would take piece of flat bar and drill and chamfer/countersink the holes.

Then I would make a simple fixture which would be a flat plate with holes tapped at the hole locations in the part. These would be 8-32 or 10-32 and they would have an accurate counterbore to the size of the holes in the part.

Then I would make some dowel bushings with a small head that would match the chamfer on the holes in the part. These would go through the part and into the counterbores in the fixture plate and would be held down socket head screws in the thread. The heads would stick up so you would just have to plan your tool path around them.

thats not a flat part
what you could do is clamp it with 2 vises side by side ,face it , cut your pocket , drill and tap the four holes ,next op bolt it to a fixture plate with shoulder bolts , and clamp it with the two vises to finish contour and stitch the arcs


then drill the treaded holes to size

you probably should do a couple of roughing ops to remove as much material as you can , i would be concerned a part that size would releive itself

I see what looks like 4 holes. These would be my hold downs. Can you use thicker stock? Then you could hold it in a couple of vises. Mill the configuration, and flip it over to mill off the back side. This may require a bit of adjusting ,but it could be done.If the surface around the holes is flat ,you can rest the part on those areas, upside down ,to mill the backside. Hope it helps.
