3DDave,
I do own the 14.5-2018 standard and use it on a regular basis, the vocabulary contained therein is extremely important so we all have a starting point. But I think there is also a reason people will pay to attend schools instead of simply reading through a textbook. A good instructor...
I'm looking for any suggestions / experiences with online GD&T training. I want to take a course alongside a younger designer I'm mentoring, he has very little GD&T and I would be somewhere in the intermediate range.
I'm hoping for a course that can give both the basic definitions and some...
Good to hear from all 3 of you again!
drawoh,
Thanks for the outline. One thing I would appreciate some more detail on in how you manage data when you create a separate dwg # for the ICD. In my mind, doing this doubles up your workload in the event of a config change, plus the added potential...
I've skimmed through some posts and haven't found a great outline for what an interface control drawing actually contains, especially for aerospace.
I get the base idea behind it, and here is the ASME 14.24 definition for reference
An interface control drawing should: a) establish and...
drawoh,
We currently use Solidworks PDM for managing all CAD files. We have no plans to move away from it, despite the limitations it has at times. I like to think Dassault put their B-Team on PDM development so I'll excuse the poor documentation and confusing terms they use.
What I'm doing is...
drawoh,
Thanks again for the wealth of feedback. I think the way we intend to use the BOM for our ERP system might be different than the standard ERP implementation. We are still in the small business range (<150 but growing quickly) and I'm not sure how the larger companies handle these tasks...
drawoh,
We actually need to generate the BOM from the model to allow our CAD to be the master. Generated BOMs are one less step than a table BOM where people can play games by adding parts that don't exist in the assy. This way all our part data is driven off PDM variables and BOM structure is...
Yes, it helps a lot more than I though it would! Our internal machinist is fine with me putting .0006, in his words "I've been making them for awhile and they go together". I can't really argue with that! But when it comes to sending parts like these out, I really didn't want to put something...
Thanks for the replies all three,
I appreciate you be willing to restate your points, in retrospect posting the pictures first would have helped so I could be sure we were all talking about the same things. I think my confusion derives from the fact that 200% gain of .0001 is still only .0003...
Chez311,
I think you are referring to the same concept that was in the other thread I listed and that also shows up in various other sources. My confusion is that when I draw up the diamond pin and its mating bushing at MMC, the benefit from the diamond cut is miniscule! I attached some images...
drawoh and jassco,
Yes, I'm with you now. I usually am the one preaching to not fight the tool to the rest of my coworkers, even if it "feels" like doing it the right way takes longer. An extra sheet isn't that much more work and is far more robust for the future designer (which might be me!)...
I've looked through some posts on this, the most relevant conversation is here: https://www.eng-tips.com/viewthread.cfm?qid=304891
We currently use the bullet-nose pins on page 12 of this Carr Lane catalog:https://publications.virtualpaper.com/steadyrain/clm_catalog_lxiii_locators/#12/...
Hi Belanger,
Yes that's the train of thought I was going off of. I'm cognizant of DoF especially when I'm working in CAD, I've had too many assemblies blow up on me because I over constrained them. I'm pretty well versed on GD&T, not on the level of some here but I think far more than the...
I am pretty fresh to design, I've spent more time working with FEA than mechanisms and alignment. I'm working with assemblies that need to be precisely aligned and I am designing both the parts themselves and the tooling to fixture parts for machining, bonding, assembly, and match drilling.
I...
drawoh,
Yes, I try to stay away from removing the intelligence from objects. There are some assemblies where it doesn't seem worth the effort of creating another identical view for a single balloon, but maybe I'm just being lazy with that. If you are talking about qty per config in the BOM, yes...
Hello,
I am attempting to use a balloon stack to show items not active in a configuration.
My top level assy has 2 configs (123-01 and 123-02) and I have parts in them (ABC-01 and ABC-02) where 123-01 contains ABC-01 and 123-02 has ABC-02.
I would like to have a single view to label both...
