Syil X7 Machining 1018 Steel

[@High_Road]

Thanks for creating the video series Kevin. I am looking forward to your weekly CAD/CAM/Machining adventures.

[@TroubledTimes2024]

I was impressed how solid the cutting sounded when milling.

[@MechanicalAdvantage]

It sounded really really good standing at the machine. A combination of a rigid machine and quality cutting tools with the right feeds and speeds (with a little help from my friends). I've wanted to move away from only machining aluminum and plastics all the time. I'm thinking of making some fixture plate accessory ideas that i've been kicking around in my mind for a bit. After machining these pieces, I'll definitely be moving forward with some prototype ideas around those ideas.

[@DCT_Aaron_Engineering]

Well those T-Nuts came out good mate. I'll send my sizes over to you ;-)

[@MrRctintin]

Hey Kevin, another really useful video, full of great content. These triple set video's with CAD/CAM/Machining are just superb for guys like me learning this art, so thanks mate, much appreciated.

[@MechanicalAdvantage]

I ordered a new LED light today. Fingers crossed this one does what I want.

[@TAWPTool]

Another great video Kevin. Thanks for sharing!

[@MechanicalAdvantage]

Thanks Guy! I received some new filming gear and I’m waiting on the last piece to arrive on Tuesday. Hopefully they will improve the video quality in the machine greatly

[@horvathcsaba1265]

I love your videos, but it takes doubble amount of time to watch when You use imperial units only since I have to stop and do the math. On the other hand I will still watch all of your videos even if you measure everything in lightyears :) I hope you keep up these coming!

[@TroubledTimes2024]

You saying there is another measurement besides Imperial ? LOL Just kidding of course, I know that feeling when only Metric is used.

[@MechanicalAdvantage]

I'll try to improve that in the future as well. I'm pretty good at CAD/CAM and now I have the need to learn some other skills like video editing a how best to use cameras. Right now I'm using Camtasia and in past videos where I have listed feeds and speeds in both units, it was really time consuming since I just used the on screen text tool. I want to look into some sort of a graphic template so I can quickly enter that info. If Camtasia can't do that, I may look at switching to something like Final Cut Pro.

[@MrCoffeypaul]

Beautiful! (GWiazrd might be a help with speeds/feeds)

[@johncarey9149]

Firstly, thanks for another great video Kevin ... 🙂 Next, I'm not a machinist, so this might be a dumb question, but why do you care about having the vertical corners of the nut as sharp, square corners? To my mind, in use, those corners will take quite a hammering when the nuts are being installed and removed, with those corners taking the most abuse, so why not allow a small chamfer, or radius on the corners?

[@MechanicalAdvantage]

I don't think there would have been any issues with a rounded corner. As you noted, it wouldn't have made them any weaker and probably would have made them nicer to handle. I don't remember exactly why I did it. It's possible it was just to show that the option was there.

[@TroubledTimes2024]

Since these are completed and to late to stop short of a full depth thread it might be a good idea to punch some areas around the bottom of the T-Nut thread to insure the stud never protrudes through the T-Nut then bottom out on the table forcing the nut up with risk of breaking the casting slots.

[@MechanicalAdvantage]

Hi Ken. The way the thread mill cutter is designed, it doesn't cut a thread all the way through the part. I've given it a try, and even with a big ratchet, I couldn't get the fastener to go through the bottom of the part. Which was what I was hoping for with the way I did the threadmilling. I would have but a decent negative offset on the bottom height if this was meant to be a through a thread.

[@RobertBrown-lf8yq]

Hi Kevin… This was a REALLY good follow up to the CAD/CAM video on that part. The cinematography will get better with practise mate 😎 Simple parts are the best subjects for teaching IMHO. Given that vids. Need to be relatively short, say 20-30 minutes, then a simple part gives more time to explain the steps, the parameter choices, work holding etc. I’m no expert mate, these are just my long experiences with trying to adapt to modern machining 🤣🤣 Regards Robert

[@TheDaumen]

Have you done any videos on champfering? I have some parts that I need to include champfering and right now it is very risky on my part. Pun intended! Poor Kevn, metrically challenged!

[@CraigLYoung]

Thanks for sharing 👍

[@MechanicalAdvantage]

Hey Craig. Thanks for watching. I hope you are finding them worth watching.

[@IceCreams62]

A little dark video around the tool but awesome job, thanks for your time

[@MechanicalAdvantage]

Thanks. Yeah, I'm really fighting the light. A black vise, black coated tool, and steel that is dark in appearance isn't helping me. I'm trying to find a magnetic LED rechargeable light that I put in the machine and remove when not needed. I've bought a handful so far, but they create a strobe effect when I record. I'll get it though. Thanks for your patience.

[@IceCreams62]

@@MechanicalAdvantage Not a big problem for sure, don't worry and thanks again for your effort for us.

[@Hanal503]

You must have had here .in this exemple.. 10 pcs ....in one stock.👏👏👏

[@MechanicalAdvantage]

Maybe you can help me out. I was trying to find your videos so I could learn some things, but it seems you you have no videos where you share your abundance of knowledge. Where can I find all of your video content? I was working with the stock I had. Therefore, I could make one piece at a time.

[@Hanal503]

@@MechanicalAdvantage I have no content on here...yet! I could exeplain more....I just watched some from you...👏👏👏

[@douglasdarby8584]

Very nice. Maybe I missed it in the CAD/CAM video, but any reason not to use a conventional tapping process? Just curious.

[@j.dietrich]

Tapping is often faster, but thread milling has better process stability. The spindle torque requirements are lower, workholding is less critical, the surface finish is usually better and you can compensate for tool wear. If cycle time isn't critical, I'd always prefer thread milling - there's just much less to go wrong.

[@TroubledTimes2024]

@@j.dietrich Yes, you also don't need a slew of different taps with the single point or single form thread mill.

[@MechanicalAdvantage]

Hey Doug! Good to see you here. I'm moving away from taps and to thread mills simply for versatility. The goal is to have a handful of threadmills that can cut a very wide variety of thread pitches. Hope you are well.

[@localele1]

I realise this was 6 months ago but if you had drilled the hole right through the part your coolant and chip flow could have washed straight out the bottom during the thread milling cycle. Cheers from Australia where my mate Aaron just put me on to this video.

[@MechanicalAdvantage]

Yep, that probably would have been a good idea. I wasn’t too worried about the coolant or chips with the single flute threading tool. I’m sorry you have to put up with @aaronengineering. No one should have to endure something like that! 😜 😂😂😂😂

[@localele1]

@@MechanicalAdvantage He is a really BIG problem over here.

[@williamregan1200]

Kevin, What are your thoughts on full axial machining with lighter radial cuts? I was told it is the modern way to machine. It applies equal pressure on the entire length of the tool and wears more evenly. Vs. just using the tip of the tool over and over again for the various depths of cut… I so far have had great success with that approach in 17-4 SS as well as 304 SS.

[@MechanicalAdvantage]

Hi William, that is my preference for sure. Had this not been the first time I had cut steel with this machine, I would have used a 3D adaptive clearing operation. Had I done that, it would have gone the full depth and around the whole part first and then would have stepped up and cut the two flats second. I just wanted to be a little conservative to start and did it the way I showed. I’ll absolutely take a much bigger axial depth cut and the same 12% stepover the next steel part I run on the machine since things went so well.

[@MechanicalAdvantage]

The other thing I should mention is that there is sort of a reverse of deep axial, light radial machining called high feed. Jason Synder (Nerdly on KZbin) uses this method on a lot of the steel he cuts. High feed machining issues a very small axial depth of cut and large radial stepover at a fast feedrate. Depending on the situation this can be faster or better in areas like pockets where deep adaptive toolpaths could encounter chip recutting because there is no place for the chip to evacuate until the cutter starts to increase the size of the pocket.

Hey Joe. We had very little snow, but whiteout conditions most of the day. I don't know about you, but I'm ready for summer. Thanks for watching.

Need chamfers😉

[@MechanicalAdvantage]

I certainly could have, but for this one, I didn't want to. The edges will get broken using a different method. Thanks for the comment.
