SURFACE ROUGH pocket

[Ocean Lacky™]

do you have open access to all 4 sides?

[HEAVY METAL]

yes

[Ocean Lacky™]

ok...i'm trying something here....working on my laptop, it's kinda slow...check back in a few

[HEAVY METAL]

thanks

[HEAVY METAL]

i'm still playing trying to get it figured out .hopefully with a little help i'll get it done thanks lacky

[Ocean Lacky™]

or, try this....do a surface/finish/contour on all the purple and blue surfaces. Use the blue rectangle at the top of the part as a containment boundary(set to Center) and try a .03 stepdown

[Ocean Lacky™]

one thing I did see.....you need to pick all the surfaces around the single surface as Check. Otherwise the tool will want to roll around the edges of the drive surface....either that or use a containment boundary.

Or you could try going into the Advanced settings and check "Only between surfaces." Typically, this will eliminate adding all the check surfaces.

thats what i,ve been doing is what thad said. also i have been using the stl file compare after verify for the first time how reliable is that?

[Ocean Lacky™]

Heavy,

 

Check out the file you uploaded this morning, this morning. this is how I would do it.

[HEAVY METAL]

thanks lacky i'll take a look when i get back from lunch

I think it's very reliable. I can't recall a time when the program violated and it didn't show up in verify. We compare ALL 3D toolpath to an STL. We only use it for 3 axis milling, so maybe others have had a different experience with fancier stuff.

hey lacky i tried what you said and saw what you did on the file. my computer is taking forever to crunch the toolpath when i select all the surfaces. onething i did notice is that your toolpath wiped out the top left side wall for some reason. maybe something to do with surface norm. what kind of computer you runnin mc on just curious. i know one thing my grapics card is a nvidvia fx5200 which is bottom shelf thats what our tech guy put in it when he built this box to run cad and cam programs go figure

[Ocean Lacky™]

The company box is a Dell Precision 670 w/ Dual 3.2 Xeon Procesors, 4Gb Ram and a Quadro FX4500 w/ 512Mb Ram. I'm running your job on my lil Toshiba Laptop P4 2.4 512 Ram and an ATI Video card.....BTW...I'm redoing the contour toolpath..should have it up in a few mins

[HEAVY METAL]

i tried moving the boundry out on the left end but that did not help was it the surface norm? nice company box how long to generate toolpath on laptop.?

[Ocean Lacky™]

actually, al i did was adjust the step down to .031 that will usually fix what happened the first time..if you look close, there was one stay cut that took out all that material.

[HEAVY METAL]

thats scary

[HEAVY METAL]

i dont know why my mc is so slow i tried to regen with .031 step down and it just got stuck .

[Ocean Lacky™]

Sorry, didn't mean to leave ya hangin...had to go do some work.....

 

I ws running into the same problem here...computer hang....I'll take a whack at it later on this evening when i get home

[HEAVY METAL]

thanks lacky i regenerated and .031 took care of most of problem except it is still wiping out the top left corner but not as much as before wierd it gouges into surface

[Ocean Lacky™]

Heavy,

 

 

Ok, I think I got it now. Check out your file from this morning....

[HEAVY METAL]

thanks lacky for taking the time to teach me some new things i,ll take a look at what you did

[Ocean Lacky™]

Heavy,

 

Not a problem, I enjoy helping out where I can.

[HEAVY METAL]

hey lacky the toolpath looks good . i saw where you added the checked surface and shallow cuts.

[Ocean Lacky™]

Heavy,

 

Something I found last night..there are 3 bad surfaces on that model.....one is the vertical wall on the top(blue) that we were using as a Check Surface. The other two are on the bottom side, fillet surfs, if I remember correctly. They're not bad enough to impact the final product, however, they will slow down your computer while proccessing toolpaths, especially when using the smaller tools and tighter tolerences. Use Analyze/Surfaces/Test Norms to find them.
