FORM BLOCK help!

[haroldm]

Hey guys,

i was hoping to get some help here. I am trying to make a form block for this part, specifically the inside shape. I have uploaded the file to the FTP (ftp://www.ppcadcam.com/Mastercam_forum/MC9_files/-155) I would appriciate any help i could get. i have tinkered with this stinkin part for almost two days now, and I could half-#$# it, but i would prefer not to. The plan is to align the part on the block with the two tooling pins on top then hammer it down. I know some genius is out there with nothing to do and looking for a challenge.. I also have MCX if that makes a diffrence, thanks in advance!!

Harold,

Check out your -155 folder.I modeled up an assembly for you in Solid Edge.Just import the .x_t into your Mastercam File.

Hey bestguest,

How in the world did you do that so fast? Is there some trick i have been missing? I have been using Mastercam for over 7 years, and although i am no expert, that part was kicking my butt!! Please explain.

[haroldm]

OK Bestguest,

Boolean remove then fillets..am i right? c'mon, it's killing me!

[bestguest]

Harold,

 

I used Solidedge to make your block.You are correct in that is pretty awesome stuff if used correctly.Solidedge has a tool called "Bluesurf" that just rocks.I took your part and dropped it into a blank assembly.I then used inter-part copy to collect the needed surfs from your model.I then "Bluesurfed" the collected faces,stitched them together and filleted the model.Done in less than 5 minutes.Put that in your pipe and smoke it!

Thanks for the help seriously, i am very much appriciative. Have a good one.

[bestguest]

Not a problem. anytime

I have not attemted it but couldn't the same thing have been done in mastercam? Create surfaces from the inside faces, flat surface on the bottom, stitch together, and fillet are all operations that can be done in MC.

[haroldm]

Hey Laszlok,

I attempted to do that in mastercam, but the thing is trying to extend the surfaces to a certain distance makes you "untrim" them, and that makes for for some bad surfaces. I am not familiar with this "stich" command, what is that?

[bellyup]

i think so. i was doing it yesterday. it got somewhat complicated because the surfaces were not very agreeable to trim functions, but no reason it wouldn't work with some trouble.

but there's no way i could have done it in 5 minutes. realistically at least a couple of hours.

maybe someone who's good with mc solids could do better though.

[haroldm]

Hey Bellyup,

Try to exteend the surfaces and you will see that they begin to seperate due to the draft angle. I would love to make this a solid in Mastercam, but so far only the Solidedge thing seemed to work. I am trying it out now, but bestguest did not leave very detailed instructions, so it is giving me a large headache..haha

[bellyup]

i did it the way your'e talking about. there's definitely some construction that needs to happen when you extend the surfs up due to separation, but with some extending and trimming i think you will end up with what you want.

what instructions did you want him to leave you?

i thought he gave you a completed part.

[haroldm]

Yeah he did, and that worked out perfectly, but I had no idea that Solidedge could do that. One of our customers has Solidedge on his laptop and he is letting me mess with it today. I was hoping to derive how he did it by his instructions, but they are not very clear, that is of course no fault of his. So anyways, i am wasting the day messing with Solidedge.

You do not need Solid Edge for this.

 

Look at -155MURLIN.MC9 in the MC9 folder on the FTP.

 

Took less than 5 min in Mastercam Mr0501. It is also a solid.

 

Could have done it in X too.

[bestguest]

Harold,

If you want give me a call here at the office.I can walk you thru it on the phone and I would be willing to send my assembly via email if you are interested.The technique that I used would be no different than pulling faces from a part model for an electrode or cavity blk.I have been doing this type of modeling for many years on different systems including using Mastercam.I could have done this in Mastercam also but Solidedge "Bluesurf" technologies just rules for this type of work.Hence the reason I used Solidedge.Call me at 262-334-4626 ask for Matt McQuestion if you are interested.

teh murlin is awesome.

 

[haroldm]

Hey Murlin,

How did you do that,if you dont mind my asking?

[Müřlıń®]

took a couple of steps.

 

 

create surfaces from solid, there were 5 but I only did the 4 big ones.

 

Untrim them and extend@ 2" all over. (more if needed)

 

Create top and bottom surfs far out beyond all the rest so you can trim the extended surfs too.

 

Trim the top and bottom first

 

Then trim the 3 intersecting surfs on the edges.

 

The small surf on the angle was made by projecting edge curves from the solid down on to the other two surfs and extending those.

 

Trim out and add a ruled in the small area.

 

Add flat boundaries for the top and bottom

 

Solidify..... Solid/from surfaces

 

Maybe not as simple as solidedge, but pretty easy.

 

 

Just have to do it in the right steps.

 

Trimming the top surfs and the bottom surfs first is the key.

 

This lines up the edge surfs for trimming.

 

Look at blanked entities for edge curves

 

I did solid fillets where I could after it was a solid body.

 

One fillet wouldn't go but if you really needed it on there you could convert back to surfs and finish it up and prol re solidify if you wanted to go to the trouble.

 

Or just let the tool do it

[haroldm]

Hey Murlin,

That did work, i remembered why i hate trimming surfaces to surfaces, but in the end, that only took about 10 minutes for me. Thank you very much, i tried that solidedge, and it seems a little more complicated than i first thought. Thanks again.
