True Position introduction (With examples & Calculations)
👋 Welcome to another episode in the Machining Doctor's classroom series!🎦 We will be talking about GD&T position tolerance. We will learn how to read its drawing callouts. What's the difference between it and conventional tolerancing, and what happens when we add MMC (Maximum material condition) to it? We will do it by looking at real examples and comparing them.

How the boring accuracy can be confirmed
I don’t understand the connection between your question and the video. Please explain. Thanks
I love seeing it when Engineers know what they are doing it when they design the printt. As a MFG. It's a nightmare when the engineer doesn't know. For example, I worked for a company where I was the machine shop manager. The engineers took GDnT training and started concerting prints from generic dimensioning to using GDnT. Most engineers thought that +/-.005 tolerance in x and y hole location was the same as .005 true position. Plus they almost never gave us MMC! So threaded holes and thru abd cbores holes for bolts became now aroubd .0012 tolerance per axis. I tired explaining and showing rhem using the chart that if they want .005 tolerance on each axis you should be around .014 TP
Nice insight. Thanks. Companies with a big gap between their design engineers and production loose a lot. Unfortunately, its quite common.
@@MachiningDoctor Yup! Very common. It's not good when machinist or programmers understand more gd&t than the ones designing parts.
Thank you for the video.
Thank you. Can you make a video on inconel and hastelloy? I’ve welded it many times and it’s tough 😅
Thank you for your video. I also like the information on your website.
Thanks for your feedback. Much appreciated!
Erez, thanks for sharing 🙏
Elon - asks the So Cal to the engineers for a stainless aloy for his cyber truck SoCal engineers- oh 303 is plenty it will live up to your hype no paint necessary. Not as expensive as or hard to machine as 316 either . Elon -Great ! DPW everywhere north of like DC - laughs and sprays chloride brines all over the roads a quarter of the year.
Are these two threads interchangeable?
No. Different profiles
very good, thank you
Good videos have less likes and subscribers. Don't know why?
Clear information, thanks ❤
Thanks, not a subject that comes up very often in the shop but good to review. Charles

Thanks for the positive feedback. Appreciated!
Great video! Your calculator is awesome! I’m an apprentice trying to decide if I should make an adaptor or re thread a 4 jaw Chuck for my lathe (Sherline). The Chuck has a M14x1 internal thread, lathe shaft is 3/4”-16 (19.05mm), but the lathe has no threading feature, CAN I USE A TAP TO DO THE THREADING? Will that be precise enough if done in this manner? My simple mind came up with the idea of machining a shaft on the lathe 3 jaw Chuck just to keep concentricity, then attach the 4 jaws one on that shaft, bore the hole, then thread it to 3/4”-16 using the tap. I have no master to teach me and no bigger machine to single point the threads. Any help is super appreciated. Thank you! Edson
Hi Ednos, and thanks for your kind words! Unfortantly, I don't have any experience with re-threading, so I cannot help you with this case. Sorry. Erez
Very informative 🏆🏆🏆
Erez, Great episode, thanks for sharing 🏆
Very informative!
Unfortunately the illustrations are not accurate for depicting threads in general and specifically neither metric nor "standard" threads, e.g. the profiles are way off.
pitch/dia combination seems like mistake, you can basically use whatever pitch you want unless it's some nonsense like when the bottom of the thread would hit the center ex. in M3x4, you can turn M105 from 0.2 above 6 just most of the pitches wouldnt be normalized
Hi, I am not sure I understand your remark. Sure, you can produce any pitch with any diameter (Almost). The argument refers to the standard combinations. It is always better to opt for a standard thread where you have the option to purchase a bolt/screw from stock. If both the male and female components are custom-made, then it does not matter.
Thank you for posting
In your speed feeds calculator the endmill with corner radius option is missing .If you add it it will be helpful because if the depth of cut is less than the corner radius of endmill then axial chip thinning factor will also come into play
Thanks for the remark. I will look into it tomorrow and get back to you.
Hi. You are right. It is something I should add. As a temporary fix, you can choose "indexable inserts Endmill" (Instead of solid). For diameters 1/2" (12 mm), or higher you can choose an enmill with round inserts. I will add this shape also for solids in the future.
Very informative as always thanks Eric and Machining doctor
Our pleasure!
316 should be reserved only for those applications where it’s properties are actually needed.
Greate to see that you have already a youtube channel! Your site is so helpful, thanks for share
Thank you for the support! I promise to keep adding videos to the channel and improving the website.
perfect website
Great resource. Suggestion: allow users to save speed and feed results to an account for quick reference ex. (.5 drill in inconel 718 ="
Thanks for the suggestion. It is already in the to-do list, but unfortunately not very soon.
It really helped me to machine Inconel 625 efficiently . Thank you
Glad to hear! Thanks for the kind words 💪
Very good and informative video , great job Erez.
