I see this a lot on drawings. This part has no GD&T applied to it, therefore our Sheet Tolerances apply.
Dimensions 30 & 50 are centered on the centerline of the part.
Do we assume the size tolerance IS ALSO the position tolerance, to sheet tolerance.
Do we assume there is "Implied...
Anybody have best recommendations for a slippery surface with the lowest wear rate?
Examples:
Teflon on plastic
Hard Anodized Aluminum on Teflon
Hard Anodized on plastic
This will be sliding wear. One will ride over the other.
Looking for a plasma cutter to cut 3mm aluminum panels. Looking for high resolution accurate cuts.
Anybody have recommendations on a plasma cutter table? Want to use one with a hypertherm cutter.
A fiber laser would probably more suitable for this but they're too expensive.
Looking to invest in a fairly small laser cutting machine. We want to cut through 3mm thick aluminum. Any brand recommendations? Fiber Laser cutters seem to be the way to go, just not sure what machine to be looking at. Cheaper the better, as these don't look cheap.
Is this legit? I can see what this is trying to accomplish, but is there a better way to do this or is this fine? I was under the impression you can only use diametrical callouts on a circular feature.
Appreciate the feedback so far. Can't share any pictures.
Racookpe1978: The stainless part is on the outer side of the press fit assembly, and the ceramic solid shaft is the inner part.

Parts are inspected when they come in. The pull force is indeed a minimum that we have call out. There was testing of acceptable fits before my time. Pull forces are not done every part, but as sample quantities to verify press fit
I'm looking at possibly heating up the stainless part, and...
We press 2 round shafts together. One piece stainless, the other ceramic. We require a specific pull force, and as of now we sometimes get good parts and sometimes bad parts. Parts are not large, they're about half an inch big.
Are there are things to consider when trying to achieve a...
First thing, I'm not an electrical guy, but I'm trying to figure this out.
I have 2 Type T thermocouples. One connected to an Omega USB-UTC that is connected to a laptop, the other connected to a Heater Controller that uses a PID controller
Both of these thermocouples connectors are fastened...
We've tried the Solidworks Inspector package. We HATE it. It is so buggy, and doesn't do basic things that we'd like to do. We've called Tech Support numerous times and have gotten the "This is a known issue" lingo. We're pretty much done with this one.
QA-CAD located here looks promising...
I've been assigned to start MBD (Model Based Definition) our models, for tolerance analysis', and possibly use the MBD to carry over into drawings. This is not the actual Solidworks MBD package, just the DimXpert that's built into Solidworks.
As quirky as trying to dimension parts in the model...
Any words of wisdom? This part is sheet metal. I almost want to suggest to just put a general note "All parts shall conform to TP .5 ABC unless otherwise specified" and be done with it and leave out the diametrical modifier.
Not only does this make more sense in my head, this is laser cut...
RFS is how it's currently called out.
I believe the intent, is to usually include this modifier for the "more efficient" circular tolerance zone instead of the square tolerance zone.
It just caught me off guard, because a circle, for every point on a circle, the opposite side of the circle...
Would it be acceptable to use a diametrical position call-out on a square feature? Trying to use a circular tolerance zone to control this, but I read somewhere you can only use the diametrical call-out on a circular feature? Can anybody explain this in detail?
I also did not have to freeze. Just a diamond coated hole saw. Same bits I use for glass. Came out pretty straight using a cordless drill, I need to get a drill press.
