GD&T Interview Questions

[@tinahawks318]

Hi Dean, Great info there. I started out as an aircraft manufacturing mechanic before making the move to quality inspector. At the start, for the most part it was general in nature, drawings, boms, general notes and flag notes, measurements, writing NCRs, etc...it didn't include in-depth knowledge of GD&T. But as I'm advancing in my craft I am coming into contact with more and more opportunities which do include GD&T, as I have been contracting for the past 12 years. I am thankful for the engineers over the course of time that took the time to converse and share their knowledge with me, and I am thankful for your work on the GD&T video series. Keep rockin :)

This man is out here doing God’s work 😅 love the videos man..just ordered my copy of the ASME standard.

[@RDeanOdell]

Thanks so much! The ASME standard will serve you well, it’s the best place to get the definitive word on this stuff.

[@veerabhadraraonalla3729]

Thank you so much brother for these videos. Actually I am surprised that you don't have atleast hundred thousand subscribers for the content you are providing. I hope you will get those soon.

[@RDeanOdell]

Thanks so much for the support! Maybe someday I’ll get there, but I’m happy to provide the content.

rule number 2 ( question 3) by default it's RFS Modifier. this is only correct per AMSE Y14.5M -1994 or Y14.5-2009 or 2018. However, for the previous year, the ANSI Y14.5M 1982, rule #2 stated that by default it's MMC modifier. i recommend to mention which version of Y14.5 spec that we are practicing here.

Hi Dean. Another great video from you, thank you. Question: In the US, would a machine shop expect that the drawings be in US inch units or would all machine shops also be able to handle drawings specified metric?

[@RDeanOdell]

Hi. Thanks so much! Most machine shops should be able to handle a drawing in metric. If they usually deal with inch drawings, they may need to order tooling, particularly for threads that could add to the quote compared to a shop that deal with metric drawings all the time. The other issue is the standard, ASME drawings can be inch or metric, and are much more common in the US. ISO drawings are exclusively metric and are less common in the US. There are some differences in interpretation, and if a company doesn’t have the ISO standards on hand, they could add to the cost.

[@peterdavila3045]

​@@RDeanOdell Excellent information, thank you. The part about a US shop having to order special tooling is very telling. No need to add to the cost of manufacturing unnecessarily. My reason for asking: I'm hopeful to have a working prototype for a product that I'm working on, by this time next year. If I can make it cheaply enough, I may even try to patent it. If so, it may be worthwhile to patent not just in the US but also overseas. So I guess the immediate answer for me is to get the cost to manufacture down first, in order to make it worthwhile to patent in the US. It would make sense therefore for the drawings for the US to be in inches and as per ASME Y14.5-2018. Then, it may be worthwhile to prepare equivalent drawings in metric, also using Y14.5 for EU and others outside of the US. I plan to use Solidworks for CAD. Thanks for all the great instruction on Y14.5. Keep it coming. I was lucky enough to take both the Fundamentals and the Advanced GD&T instruction courses from AGI. That was great, but your videos are a great way to see GD&T explained by a Machinist and from another point of view. I have the Y14.5-2018 standard and Machinery's Handbook. I also just ordered Bruce A. Wilson's "GD&T: Application and Interpretation" book, as per your recommendation in some other video Thanks for everything.

Rule # 1 can be called the envelope principle per Al Neumann, just an observation

[@hypnodink]

I took a GD&T course from Al Neumann as an intern in the early '90's. I'm now a design supervisor and our business contracts with his son, Scott, to train our new designers through their company, Technical Consultants, Inc. (TCI).

[@akshaykhade4376]

That was good video. Now learned how to interpret modifiers.

[@gdtguychuck]

This is a fantastic video!

[@RDeanOdell]

Thanks so much!

[@chuckstemke2420]

@@RDeanOdell I suspect that 9 out of 10 working machinists and a similar number of working designers could not tell you the meaning of Rule #1. I went to two years of machining classes at community college and it never came up. I worked for five years as a machinist and if we talked about GD&T, it was only to ridicule engineers who attempted to use datum symbols and feature control frames. It is a shame. The concepts should make a lot of sense to anyone who does this work, and when explained properly, are eye opening. You are the best on KZbin - keep up the good work.

[@birkanalismibulamadim]

Hi from Turkey! i liked your video an i subscribed, but i'm little bit far to engineering literature in "english" so could you add some texts or subtitle to your videos? thx

[@michl.182]

Hi, all KZbin videos have an option called “CC” (Closed Captioning). It is located at the upper right corner of every KZbin video, you just click on it to activate it and you will be able to see the subtitles of each word the person is saying.

@@birkanalismibulamadim I'm certain Mich L. deserves and prefers to be addressed directly as Mich L. and Not by the informal generic street name "Dude". Also, get over your demeaning sarcastic attitude to someone who took the time and effort to give a bit of help. Mich L.'s response was in line with a "1st of all, in case you're not aware, try this...", since you gave no other info than simply a generic-formed question.... while noting your post is from Turkey. Perhaps your response was not meant to be sarcastic and disrespectful due to your having to express your question in a non-native language, which is commendable in effort. So, for your future questions in English (or other in which you are not fluent), it may be effective to excuse your seemingly ill-manner in posting your question(s) and/or your response(s) by offering in advance a little statement of apology if your post comes off un-intentionally rude, sarcastic, and/or demeaning to anyone taking the effort to help you.

Each time after facing the interview, i will ask the interviewer about my performance and areas to improve, the one and only reply i get is.. "IMPROVE BASICS OF ENGINEERING" what does this "BASICS ACTUALLY MEAN", how can i overcome this, anyone reply me and help me to crack interview

[@Anonymous99236]

For eg; Mechanics-types of stress ,stress strain curve,mass moment,etc! Materials-properties of widely used industrial materials(toughness,tensile strength,etc) and difference between them(mildsteel cast iron,etc)! Machines and components (compressors ,flange,coupling,etc)! Units and conversions (eg; Deci cents kilo mega,bar,pascal,etc)! Laws of thermodynamics and Newton ! Instruments like VernierCaliper,Micrometer,etc! Basics like this for all subjects and specialise some particular subjects and subfield(eg;hydraulics pneumatics ,sheet metal,etc)!

[@Anonymous99236]

Can you make a list and tell me all the question you were asked in the interview?

[@asan203]

The better answer is you should ask the interviewer. Most of the interviewers will surely reply
