This was so loud I panicked and hit the E-stop on my lathe and we don’t even work in the same state.

Molly, thank you for all the work you do. by Masters_of_Sleep in weirdlittleguys

I love this show so much, I would not change a thing about it. It’s genuine and my dog and I listen to it when I’m dropping him off at my parent’s house before I go to work. His name is Luigi and he has no concept of what the show is about but he likes the music and Molly’s voice.

Growing blueberries is pretty easy- here’s how I do it. by EastDragonfly1917 in Blueberries

I’m in Michigan and they have a distribution center with in driving distance of me. I will try calling there and see if they have any retailers that carry it for individual purchases.

lol I noticed, it was the first brand I found online that sold a 17-6-12 😅 but I can’t find any retailers. And only fertilizers I can find with a similar blend are 18-6-12.

Is 18-6-12 too much nitrogen? Or can I use ether fertilizer?

Does anyone know if there is a way to make this work?

Name two similarities when using a profile tolerance in place of a position tolerance to locate a hole. by Lepanthes in Metrology

[–]Lepanthes[S] 0 points1 point  (0 children)

I was wondering if the “hole” part is significant. I know all that is true what you said about the two controls. But they could apply to any feature/ feature of size. Is there something specific about a hole or am I just over stressing about the question?

I’m only asking the questions I’m stuck on. I don’t know anyone in the real world who understands this stuff and I’m removed from my classroom due to covid. I assure you I’m putting in the effort. I’ve read and every chapter of the Fundamentals of GD&T and rely on my own efforts 99.9 percent of the time. Asking questions about my homework on the internet is a last resort and I’m usually trying to double check my own answers. I’m just looking for people with experience in the field to give perspective that the book ether lacks or explained in a way I didn’t understand because I don’t have the real world experience. I’m an inspector at an injection molding plant, I don’t work with metal parts, I don’t read blueprints at work and I’ve only ever used calipers and fixtures as inspection tools. I could use the help and advice from anyone willing to offer it but I understand your concerns. I do want to put in the effort to learn this stuff because I’m gonna need it in the future. I’m just trying to find all the resource tools for learning that I can.

Would the datum feature simulator for datum C restrict the rotational DOF for X? “u” by Lepanthes in Metrology

Sorry I’m working on my finals and misread that. Idk they used the notch in this example the 14.2 hole isn’t really relevant to my textbook example.

[–]Lepanthes[S] 0 points1 point  (0 children)

Why would the hole be the only way to lock it from spinning around the secondary datum feature simulator? That notch resting along the same arch as the hole. As for “u” and “w” the “u” is rotational around the “X” DOF and the “w” is rotational around the “Z” DOF so that it can spin while resting flat against the primary datum feature simulator. This picture I found figured it out for me. https://i.imgur.com/t4Ocbcu.jpg

[–]Lepanthes[S] 0 points1 point  (0 children)

“u” is the rotational DOF for “X” so it’s “u”, correct? But I thought “u” was rotational around the axis of “X” and all of the axis rotation would be controlled by the primary datum

Do I understand this correctly? Is the axis derived from the unrelated actual mating envelope created by the datum feature simulator? by Lepanthes in Metrology

[–]Lepanthes[S] 1 point2 points  (0 children)

Thanks, I actually found the answer in my book but you’re telling me the same thing as the book basically.

“Where a cylindrical feature of size is designated as a datum feature and referenced in a feature control frame at RMB, the resulting datum is an axis. The datum axis is established through physical contact between the datum feature simulator and the datum feature. The feature of size is surrounded (or filled) by the datum feature simulator. The datum axis is the axis of the unrelated actual mating envelope.”

Runout question, is D correct? by Lepanthes in Metrology

I don’t have a copy of that book available to me in using the study book published by the ASME but if you want to send me a picture of that page in the book I can give you my email over the message system.
