Thanks Adam. Fancy chamfers are just tooo easy to add in Solidworks! I know you likely don't want the hassle but if you ever had a YT channel supporter t-shirt it just has to say "It's not ours to ask why, it ours to build the die". Thanks also for not skimping on the maths.
A bit closer to origin sounds better in my opinion: "Ours is not to make reply, ours is not to question why, ours is but to build the die" bit long tho
indeed, the audio quality is actually acceptable, but very very quiet - a boost and normalization in editing would be a massive zero-hardware improvement :-)
Have you heard a machine shop? My ears done work to well anymore and you guys are worried about the fine vocal quality of Adam's presentation? I'd suggest more content before worrying about you sound quality!
I'm a programmer, not a machinist, but I absolutely agree with you at the end. Arguing with customers about design choices is almost always more exhausting than just doing the work how they want it done.
The only problem is that when the end product comes out poorly, the client starts to blame it on you and cite non-existent claims like how another company did it the way they asked and the product came out perfectly (which contradicts why they came to you instead of the other company in the first place). Then you gotta waste your time dealing with their nonsense. It's the same for all industries.
@@joehoandroid komplizierte, oder (aus verschiedenen Teilen) zusammengesetzte Fase. Also genau so, wie die Fase (= Die Fase ist eine abgeschrägte Fläche an einer Werkstückkante), die im Video zu sehen ist.
I have found literally no material that covers compound angles. I would love a segment on this topic. You communicate clearly so I’d love to hear you talk about this tricky subject.
Leaping from compound chamfer machining considerations to design/engineering/manufacturing philosophy to full on life and existential matters in one minute was amazing, and I'm 100% for it. Gotta love machining... For what it's worth, I normally sit on the other side of the mouse and I use the chamfer/radii tool with great restraint. Because with great power comes great responsibility.
"It's not ours to ask why, it ours to build the die". As long as you are compensated for your time and the aggravation factor , I would agree with that.
Overdesign happens in every field. You have a very healthy attitude toward it. It is actually more stressful collaborating on the design side with colleagues who have a tendency to overdesign. It is harder to not push back.
I love your attitude about your customers possibly over designing some aspects and, where you might have pushed back, in the past, today you just let it slide. I agree with that let it slide attitude. Thanks for sharing! 🙂
This is the stuff I send back to the customer and tell them they don't want to pay me what it would cost to deal with their design. Good thing guys like you are out there to get stuff like this done!
These are some of the best high precision machining videos on youtube. I've just ripped through your entire uploads and i am really excited to see everything you have to share! Good luck and thanks!
Nice video. Speaking as an engineer though, at least where I come from, we generally appreciate input from the manufacturer on ease of manufacturing. We've saved a lot of time and money by listening to ours. These days, with our suppliers being mostly CNC based, it's usually more about what to machine fully and what to weld together from smaller parts though.
Yes, sometimes the lack of communication between the engineering and manufacturing results in very expensive and longer times. A complete stupid thing from engineers not listen the machinists feedback. But in my country sometimes the shop knows that is a better/easier way but they make more money the way you asked so they do the more expensive as requested.
that's why engineers with manufacturing experience are great. btw did you know that you can friction weld wood? I learned that in my engineering book. basically rotate a dowel into a slightly undersized hole, and then use a hard stop, you can also use that for surface on surface with a linear motion.
also even with cnc, sometimes the choice of material or process can matter, I saw some dude fully 3d print a speaker box as a rush job when he could have at least made the base with a hand router and guides and saved like a day of printing (out of a 60 hour print.) and even then, the sides could have been cut mdf and saved even more time. cnc is great but it's also not magical, and some features can be impossible on some machines and require costly changes of manufacturing or simply remounting the piece (for example clipping the toolhead when putting a hole next to a corner).
I'm VERY SLOWLY adopting the same mantra, of "why push back", for the same reason. Your own happiness is more important and finding a way to get there is the only thing that really matters. Another great vid by the way. Good presentation of the details makes the in-depth content really watchable.
New subscriber here. I'm a former mold guy who now works in a stamping die shop for a huge company. Thanks for sharing your work and keep up the great work. Great channel and content.
There's always a difference between what people need and what they want. If a customer gets too full of themselves to listen to feedback, that's too bad for them. I agree with you on your last point. If the problem is manageable, it's a good exercise to figure it out if only for your pride of profession, and sometime in the future, some customer will consciously require that feature, and require it to be made well.
You sure are a natural communicator, thanks for the care and effort you put into your videos. (plus I love all the "trippy" instruments and tools you have).
Loved the video Adam! This is a side of machining I’ve never had the pleasure of learning. Could you do a video on shop math? Tricks for remembering trig functions? I think people like me would find it very useful!
I will most likely not own a surface grinder for the next 40 years, but I really enjoyed watching this. And I would like to complement your warm and calm voice over! It is very inspiring and I hope to be as relaxed for my video voice overs one day soon. Best wishes from Denmark
Oh, you are my new favourite machinist on youtube! I dont have a surface grinder. I havent even seen one in real life, but this was enjoyable. One question that popped up all through the video, you answered in the end. Great stuff! Thanks!
Thanks to YT algorithm I now watch _this_ Adam do machining :) While I keep dreaming of a little lathe or a mill in the garage, this sort of stuff is never going to be my task… but I love learning about it, and it is fascinating stuff. Thank you! I also really like hearing from craftspeople about their approach to dealing with changing environments, and clients - that’s always interesting and often transferable into other trades ;) Adam, a lot of your fellow YTers make adverts for Skillshare - grab yourself a free trial and pick up some tricks about audio post processing :) Your delivery is wonderfully calm and precise, but sometimes hard to hear. Of course, a clip-on mic would also help, but you can achieve a lot with the gear you have. Looking forward to the next one!
Great informational video, it was awesome explaining on that kinda chamfer/ lead-in. I machine a lot of those chamfers on the automated type parts that I make in my shop
Such an awesome video - just subscribed. I appreciate you doing it on a manual machine like this. Could you possibly address the audio issue on your next video? I have my system sound, YT sound, and speakers maxed out and still can't hear everything that well. Don't want to miss the great knowledge and experience comments you have!
Nice job. I'm a mechanical engineer with a machining background, and I'm thinking to myself why in the world does the angle need to be so precise. I appreciate your explanation for not pushing back, but I don't know if I'd be able to keep my mouth shut, ha ha. When you dressed the side of the wheel, did you need to be at the exact CL of the wheel? If off the CL, would the angle dressed actually be different than the angle desired?
You do need to take care to position the dresser at center . What wasn’t filmed is confirming the wheel angle by grinding thru a thin razor blade and checking the angle on the microscope . Some people also use graphite . If you search “superb industries tour” you see me giving a tour of my old jobs grind department and we go into detail about that .
I know a lot of people shy away from math, but I wouldn't mind a more in-depth explanation of that. Stacking those trig functions becomes a little hard to follow what each one does in relation to 2D space. It is an interesting decision, do we quote the part to the drawing or offer cost saving / time saving suggestions. I dont think there is one answer for every shop / customer / situation. It is interesting to hear individuals thoughts on that.
If the customer specifically ask me to make some recommendations for dfm I’ll do that , but usually the process and emailing takes as much time as making the original feature
@@adamthemachinist Thats a good point, especially if you are just making one piece. It's probably a better use of time to make it to the drawing than sit around waiting for a reply.
I like to set my audio to just touch the red bar. Every sound layer can be around 12db lower. Not a hard guide but I hope that helps. Otherwise good format and topic!
That’s a good way to think about it. Don’t worry about why the designer wants it some funky way. Be proud you can deliver the specified part no matter how complex it is.
That is a really neat dresser. I would suggest over a screw that could get in the way a nice lever arm where 10" of travel gets you 1" of dresser motion. Cool Stuff sorry I had not stopped by in the past. Subbed :)
Thank you so much for the end comment. I'm feeling that burnout quite a bit lately soeaking with engineering or managers about what's right and your comment reinforced a small amount of do it to the print and let them see the cost and make their changes after. If they choose to pay for that surface, I make that surface and live content the bills are getting paid. Still sucks, but another prospective i can sock away when the going gets tough.
Audio seems to be my nemesis. Ultimately I don’t have much time or desire to buy camera gear, so I film all day with the gear I have and try to make the best of it when I edit it together .
@@adamthemachinist Great video, although maybe a graphical explanation of how the dressing angle calculation goes could have been nice To be fair the audio quality is acceptable, but mostly very quiet. Amplifying (each section up to 0dB) and/or compressing (the audio kind, not filesize kind) in editing (eg. Audacity) would be a huge improvement without any extra hardware :-)
@@adamthemachinist I was referring to the angles you used in the formulas on the calculator. On the first formula for rotation angle, if the bottom angle was 30° and the short side that you dress the angle on is 15°. would the formula be arctan(cos(30°)*tan(15°)?
This was so interesting. I don't know if I'll ever get to grind so this is fun to see how guys do grinding. I would love to see how you use your cnc grinder too
Hi Adam. I really like your content. Very informative and practical step by step. I also liked what you said at the end about accepting the possible design mistakes, I still try to get around it when quoting. I would like to know how you quote jobs, for example this expensive chamfer job. Thanks for your videos and looking forward for more, subscribed!
Pay attention, fellow engineers! Unless there is a functional need for a compound chamfer, listen to a good machinist before you just let SolidWorks make compound chamfer and save yourself/your company some money. This is very skillful, friend. Well done!
Got your channel recommended on the front page, so kudos. Audio needs some love, like the levels are way too low, not normalized, There's some echo when you speak to the camera. Other than that it all looks pretty great.
do you process your video audio with eq, compressor, noise gate, or gain control? what would it take to get you a lavalier mic and audio interface? there is too much of a jarring difference between the audio quality between the live video clips and the voice over parts. loving the content, sorry for the unsolicited audio criticism, cheers
Your channel looks really good, and the thumbnails look very clean and attractive, the only issue with video for me is possibly too much lighting when you are talking to the camera, and some time down the road an upgrade in audio recording device might serve you well, but even still, your videos are clean and well edited, keep it up!
omg. so you change the shape of the GRINDSTONE? man i thought you had to use some sort of omega dremel bit with a 4D axis arm to get weird chamfers. Completely skipped through the technique! great video thanks for the concept!
Truthfully though, during my apprenticeship I had to take a 50 hour class exclusively on compound angles in toolmaking. solving for tilt and nod work in mills, double angle plates, and angle and tilt/rotation work. all work had to be sketched out as the three triangles forming the compound angle and solved with trig tables. Great course, really made me learn to not fear the triangle. Of the 8 of us that went thru it , I'm the only one still in the trade :(
@@adamthemachinist Dang, thats completely missing from my education. I have to figure stuff like that our in Cad. I feel like thats a serious lack on my side.
Great video. We used to grind 3mm x 10deg on the inlet to the material guide, whether it was fixed or a lifter. A pain as we used carbide there (running full hard phosphor bronze)
Honestly, in a way that no other channel has, you make this middle-aged home-gamer want to quit his desk job and take up an apprenticeship as a tool and die maker as though he were fresh out of school. That's down, I think, to your attention to detail and your willingness to teach.
@@adamthemachinist The levels are a lot better than they were. 👍 An inexpensive lav mic would help a lot when speaking to the camera. Thank you for making the effort to improve your audio!
@@adamthemachinist In your video editor of choice look for an option called normalise audio and apply that to each clip for the next video. Normalise to -1dB to give it a slight amount of headroom. This will look for the loudest peak in the clip and then bring the level up to the target that you've set. This will also bring up the noise floor, which is not apparent for a loud clip but will be apparent for a clip that was recorded very quietly. To combat this adjust your gain during recording such that the loudest sound you expect to record is just below clipping. If you have a clip where the gain was set too low and you need to use it you can try to save it with some noise reduction but too much will make the sound very unnatural. If you have questions I'm happy to help, I've worked as a videographer and editor on the side for a few years. I tried linking to a guide once before but youtube decided to remove the comment.
That would kick the horizontal chamfer onto an angle and you would need to dress the bottom of the wheel then . The two chamfers aren’t actually 90 degrees square to each other
