You should start a separate thread for this question.
Very few casters have metal wheels and tires. Are you asking about entirely non-metal casters? How strong must they be?
I don't see the point of specifying any material conditions on tapped holes. Tapped holes centre their fasteners, and they are pretty accurate anyway.
I used LMC on a casting I was designing. There were two holes in the casting that were to be accurately machined out. I was concerned that...
What sort of a student are you? We have a forum for students to post in.
If two steel objects collide, the kinetic energy is converted hopefully to elastic deformation. The elastic deformation then converts back to kinetic energy. Any deformation other than elastic is what we engineering...
AriRnD,
What you need is called a bulkhead fitting. Your part is not properly retained in your hole. Is the flange connection supposed to be sealed? Forget it.
A bulkhead fitting is retained into the panel by a nut, by screws, or by snapping in. Your hose is attached to a completely...
bc23,
Is this your drawing, or are you trying to interpret something somebody else has done?
Your hole can be perpendicular to your datum in one axis only. Your curved face defines an axis, at least, geometrically. Have fun figuring out where this axis is in your inspection lab.
If you...
If you redraw your part in 3D CAD, you can reproduce the drawing in inches, and quickly check it from the original drawing. If NX is anything like Solidworks, you just change the drawing units. The tolerances will convert. In Solid works, you must convert feature control frames manually.
Can...
Ctopher,
The STEP 242 models provide dimension information. What do the 3D PDFs do? If I have a drawing with dimensions, I can measure with scales, calipers, and micrometers. I can set up gauge blocks and dial indicators on the granite block, and I can design tooling and get someone to check...
I designed a laser shutter that had a descending force spring. It took around a pound of force to start it opening, and then it dropped to a fraction of an ounce in the open position. I selected a motor to actuate it such that it required 10V to open, and 1V to hold open. Thus, I minimized...
Sparweb,
Oglethorpe's authority comes from you assigning it to him.
I agree that QA procedures must be reviewed and updated periodically. The fact remains that you claim to have QA. You promise to follow QA procedures, and then you follow them. As your insurer or customer, I am an...
I have already replied to this, but I am thinking it through a bit more.
For fifteen years, You have been working with and supervising someone named Oglethorpe. You have a task to be assiged, and you know that if you give it to Oglethorpe, it will accomplished quickly and effectively. You...

I have been playing a bit with the cloud-based OnShape. My precious files are stored on servers located somewhere, and controlled by PTC. I am at the mercy of their security and any future business models. I would prefer it if my data were stored on my hard or solid state drive...
I asked ChatGPT about "bristol centaurus engines". It got the number cylinders right. It got the displacement wrong. It listed three aircraft in which it was used, one of which actually did use it. It did not mention the sleeve valves it used.
Should ChatGPT have anything whatsoever to do...
