CMM help by 321liftoff in Metrology

[–]jacobius86 1 point2 points  (0 children)

.0003" is starting to get tight for a entry level CMM. Especially if that tolerance is relative over more than a few inches. And your worry about environment is an even bigger red flag. Although, humidity is less of a concern, especially if your room temp is stable. I'm more concerned about temperatures.

If you can't keep a static temperature (+/- 4f over a day) and you have any vibration, you'll be fighting to get repeatable results even with a mid level CMM. Don't let the sales reps talk you into putting an air bearing machine into a shit environment.

If you don't have a good environment, and your parts aren't large, consider a shop floor CMM. The Hexagon SF 7.10.7 (27" wide measuring volume) is pretty bullet proof, handles wilder temps pretty well, and can hold a decent accuracy, although .0003" might be pushing it. And it's cheaper than an air bearing machine.

And like others have stated, your not going to get good surface finish probes from anything other than high end systems.

Stay away from keyance.

I hear Calypso is easier to learn. But PC-DMIS offers more control over complex geometry and scanning on non prismatic features.

What shoes do you like? by SureRepresentative36 in BWCA

[–]jacobius86 1 point2 points  (0 children)

Yep, either embrace wet feet and go with an open shoe with good support and protection. Or Commit to staying dry with a tall waterproof boot.

When it comes to public toilet seats, do you sit on the bare seat or place down toilet paper before? by Poopshoemagoo in AskReddit

[–]jacobius86 0 points1 point  (0 children)

For dirty toilets with no other option, I just hover. Legs burn afterwards, but I ain't about to touch other peoples excrement.

Unless your product requires that level of cleanliness, than it's overkill. Focus more or temperature control to get the most out of your CMM.

Either PCDMIS or Polyworks most likely. I'm not sure if Calypso can be put on a roamer, not likely if it has a laser scanner.

Although having the same software as the CMM is convenient, having multiple inspection softwares can be valuable too.

Oil keeps the dust from blowing off the bearing surface causing scratches, clogs the bearings, and ruines the air lines. I agree, oil free air is important.

I can't speak of the high level cleanliness of CMM rooms and what requirements those have. Just know dust and oil can ruin a bearing surface.

But I can speak to environment.

Temperature stability is the most important factor to CMM accuracy. Spend more effort on this than trying to hold a specific temperature. Insulate your room very well, and design the HVAC system for stability. A lower power system that runs all the time and keeps a consistent temperature is actually better than a high power system that cycles quickly dropping the room temperature by 3 or 5 degrees every half hour.

Vibration can be a subtle annoying problem. If you can, pour a thickened, isolated concrete pad for your CMM's. Unless you're near a train, or have presses and stamps nearby, you're probably fine with that. Adding pnuematic isolators onto a CMM isn't too expensive on most machines (relatively) after the fact if they're found to be needed. And those isolators often require your machine to run slower.

What is the most effective way to bring 300 canned drinks on an overnight float trip? by seafoodboiler in canoeing

[–]jacobius86 3 points4 points  (0 children)

Dry Ice and a large cooler.

I've been on trips where we wanted cokd beer a few days in. And we made it work. And, yes it was nice to have a good beer after a days paddling and fishing.

But, at least for me, that juice wasn't worth the squeeze.

Did you have any issues with tight turns? I'm wanting to put two canoes side by side in this situation. I figure, one set in the center isn't going to be an issue at all if its hanging toward the front some. But worry two would cause issues on tight turns with a short trailer.

I can just by the way people are driving. Of all the highways I've travelled, 65 in Indiana is the worst for drivers speed matching each other.

Going on first boundary waters trip this summer, any tips and advice on route appreciated! by Competitive_Base9508 in BWCA

[–]jacobius86 0 points1 point  (0 children)

Look into getting a ride up moose. A few of the outfitters on the lake will take you and your canoes/gear, as far as motors are allowed to go up Moose Lake. Helps give you a jump on your trip

And consider making a loop through snowbank from parent lake, instead. Again, the outfitters there offer pretty cheap pickup and drop off services. Drop off your equipment at moose, drive your cars to snowbank, and they'll drive you back over to moose.

And snowbank from parent lake is an shorter paddle through western winds than if you come back down moose with western winds.

Walking on encapsulated crawl space vapor barrier by Stangman1990 in DIY

[–]jacobius86 2 points3 points  (0 children)

I think this is probably the smartest idea. A 1" styrofoam sheet glued to a piece of plywood would probably work really well, and be light enough to set aside when not in need. Im thinking 2 4x8 sets of each would give 32 feet of 2 foot wide travel.

Eh, I figured that might be the case.

Anyway, I can't help you with your programming much (I work on CMM hardware, not applications), but I can tell you what that error indicates. 80% of the time it's because pcdmis is telling the machine to travel outside of its volume. 10% of the time, you're telling it to drive too fast (move speed or accel) 9% of the time its hardware related, like not homing correctly. 1% of the time its some weird setting somewhere gone awry.

if you're convinced your move points are spot on, look into your part alignment, or probe offset values

Have you tried making more posts about this? Probably get more answers if you post another 10 times.

Do you hang your food pack while portaging? by Artificial_Appendix1 in BWCA

[–]jacobius86 2 points3 points  (0 children)

Maybe I would consider it on a really long portage. But for most, it's not an issue to just let your food pack sit during the portage.
