If people dont enjoy watching Adam learn CNC, which i think is doing an excellent job, then go watch Titans of CNC. Adam is one of the most skilled machinists I've had the opportunity to watch on youtube. I've been a machinist for over 20 years, and I've learned quite a bit from him. At one point in time, all of us had to learn CNC. I struggled a bit at the beginning and made my fair share of mistakes, but it molded me into the programmer i am today. I think it's awesome him watching him learn and continue to improve upon his CNC abilities. Keep the videos coming, Adam ! Great job!

Thank you Adam. I appreciate your sharing. F the haters.

The variance between pieces for angle is why we were always quite liberal with our CNC code where I used to work, and we typically used spade drills for most bolt holes. This way we could get fairly uniform holes with only having a few tools, just needing to buy the spade inserts for what we used, and the ones we used also came in carbide, for heavy repeat work. I do like the helical milling for the holes that you did too though. Personally I'd probably only use that for more stable dimension materials, unless I put in the max variances in the code... but that would make it run a bit longer than necessary.... drill cycles also tend to be way faster than helical cycles... but practice is definitely practice. Keep up the good work, and thanks for showing us these projects, simple or otherwise.

Hi

If I had to do it all over again I would like to have learned machining and possibly made a career of it. As a young 20 year old I was fascinated with the process but a Military career to me in other directions. Never the less I do enjoy the machining & milling KZread channels.

Hey Abom, i think its a big value for all those who want to get into the CNC machining, you are doing them all a great favor the way you explain your operations and the way how you share your journey into this new chapter !

Something to help you out, edit the end of your program to send the tool to machine zero. I've noticed at the end of your program you leave the tool near your last cut so when you change the part you are working around the tool. It will help a lot when you are running a bunch of parts.

Another excellent learning experience. Looks like he’s getting more comfortable with ‘the CNC way’.

I for one will never touch a lathe, or a CNC, or any machining system, but I still find these videos fascinating.

I personally really like seeing the cutting with coolant, that's just my preference though. It also gives me a lot more peace of mind watching this lol

If the holes are meant to hold bolts isn`t the hole location a little close to the wall?

Great video Adam. Bet Joe at the Weld shop is going to need a new batch of these angles unless he has some very special nut being used. Doesn't make sense with the large clearance hole and being tight against the inside wall and radius. Let us know the outcome. Thanks for sharing.

My first thought! There's no internal clearance for the size of nut or bolt head that would need a 13/16th hole, even allowing for a little wiggle room.

Adam, fellow Milltronics user. We have a G32 in the end of code to take the tool out of the work area to toolchanger height. A G28Y0 will take the table to the operator. You may want to add a X component to that also. Awesome work !

If I were buying the tool bits and cutters etc. I would probably use the flood coolant all of the time. I agree, with all X,Y and Z programming, its likely a better idea to give more room than trying to start super close due to the variables in the stock material.

Very nice work sir

I use tungaloy high feed mills every day. The 2" 5 flute is a beast and can turn a full 30hp into chips. That tool you are using can be had as just a head that screws into a carbide shank. When you have to reach 4" into a tight spot with a small diamater tool, that is the best one ive found. The MJ inserts last longer throwing sparks with an air blast then they do with coolant.

Tungaloy is the king

A36 is mystery steel, you never know what got recycled to make it or how homogenous the mix got. I've taken to treating it like 4140.

That's awesome Adam. The old mill scale is tough on any tool you shove through there fast with or without coolant.

Gotta get me one of those tape measures with the extra large #'s . Retired electrician and drove me crazy hitting a hard spot while drilling in angle iron. Was told they use everything but the kitchen sink scrapes to make it. Used 4 by 4" angle iron to fasten 4 by 4" wood legs to my home made work bench. Used recycled 3 by 10" wood for top of bench. Thing weights a ton.

My dad started building a machine shop when I was in high school.. Had a manual mill, lathe and shaper to begin with.. He found some old K&T Milwaukee-Matic (60's vintage NC).. Once we got the cnc bug - we never went back. We ended up getting rid of our manual mills... It is so easy and quick to setup one offs with a cnc vs manual. Keep learning!

i have to say youtube not letting me get notifications on some of my subscribed channels is a bad thing and a good thing. i just spent the day catching up on your videos Adam. Just me with a beer and some homemade bbq ribs. Thank you for the great videos Adam, this content is my relaxation therapy.

When I drill holes like that it is usually an accident and they don't come out round.😂. I hope experienced machinists don't mind your explanations. I am not a machinist at all. I just appreciate watching true craftsman doing their thing. So for a guy like me all explanations are useful and adds a lot to the viewing.

I have fond memories of Adam cooking us some killer lunches at John's shop doing the scraping class down in Florida, Adam and I spoke about him getting into CNC and I'm very happy to see he took the plunge and is doing well with it.

@abom79 little tip turn the pressure on your air gun down a bit, if you have it too high you can blow chips under the way covers and its a royal pain to remove them and clear it all out. The other thing you can do is put a diverter valve on your flood coolant and have a low pressure wash down hose.

Nice movie!

Helical interpolation = needing WAY fewer drill bits. I really have a small inventory of drills over 3/8". For low volume, interpolating holes is easy gold.

Have you considered adding a command at the end of the program to raise the head up and away from the surface? It would make loading the pieces easier and less chance of hitting the tool.

I use G30 for this

something you were missing about the sparking of the inserts. The reason they sparked on the first couple is because by the tip it starts to break thru the other side the material gets thinner and ends up hitting the face of the cutter more. Then when you added the jacks it was constantly pushing the material back up into the cutter.

Adam, with the CNC jobs note the spindle load during different parts of the job. Because it's CNC those loads should not change much part to part. When you start having worn tooling that number will jump pretty obviously.

Put at the end of the program, G53 Z0; G53 Y0; M30; It will bring the Z up and the table to the front at the end of the cycle.

When ending the program home the tooling to the back to minimize the risk of hitting it with workpiece or your hand ! Ask me how I know !

Nice to watch. Depending on tolerances needed these could be a very fast punch job. 4-5 pieced per min. I will say though circle interpolation seems as fast as drilling.

When I have millions of M3 tapped holes in a part, I do the same thing. .093" end mill and a .098" thread mill that has single thread cutting head and I interpolate the holes and threads. I do alot of copper and aluminum heatsinks that can be expensive mistakes if I break a drill or tap!.

G'day Adam. Great watching the CNC doing its thing. The carbide insert drill works like a dream, & considering the lifespan of the Carbide Insert, then it might be better & faster than an Annular Cutters, & cheaper. Great video

Precision parts drilling

All the people saying a nut or bolt head won't fit, without knowing the application who knows, it's possible it's welded on where the bolt head is on the outside away from the leg of the angle and a long bolt down thru to who knows what, or they may be to clamp down into a groove or something hence why they want it near the vertical leg.

It's no problem that the chips are hot, if you want to kill the inserts faster use water.

Could just be material. Another indication of wear is watching load meter on spindle. Watch it as it runs. As you get through parts and your load meter starts looking higher through your cycles you’ll see it

Thanks, Adam, for using the Renishaw probe, at least during the setup :). Sometimes you have to use tools to find out when and where they really are useful and when not. Goodwill and trust from a long-term customer is money in the bank. To a certain degree, so is the little program that you created, tested, and improved. Save it, document it, and it might be reused as a first step toward solving a next job. Is it possible to get your mill to report how much power the spindle motor is using during parts of the program? Comparing the actual rotational load to a reference load might give you a good idea of when you need to replace the inserts or to change your approach.

Have Z return home/tool change position and position x and y so it’s easier to change parts.

I noticed that the sparking reduced markedly when the improvised jacks walked out. Check the video.

So is there a batch of machinist jacks as a shop project coming up?

If clearance heights provide for it, an adjustment in your Z- in you r g54 and g55 will work or you modify (edit) you clearance heights and your G54 and g55 Z- will do the trick. Saves time of revisiting the Computer.

I suppose you noticed too that the sparks disappear through the majority of the cut when the jacks are not present or loose?

I would aim the coolant lower to hit the inserts instead of the shaft of the cutter

Does Fusion properly account for feedrate difference at the outside of the cutter when making holes that are that close to the size of the cutter? If it is just taking the calculated feed rate from the chip load and running that at the cebter of the cutter, it'll be way faster than you expected and could be why it needed coolant. There's a good HAAS tool tip video on that.

on CNC machines you climb mill. on a bore that means going anti-clockwise

I finally did my first lathe after years of watching and learning. Got a used Grizzly lathe/mill combo. I like it but I'll get a better one later.

Funny comments about sparks. Really funny. So, as you get to the bottom of the material you are drilling and milling, material is thinner and as such builds up more heat. Therefore the sparks. You can easily run these inserts without coolant especially on this type of construction steel.

Need a new thing, the clamp jack. It has a top portion that can be tightened around the edge that the jack sits on. Never been designed before so you'll have to get to work.😁

I was so let down we didn't get to see the first cut😂😂

it's starting to spark out because the material at the bottom of the hole just deflects instead of shearing off. If the material thickness is smaller than the entry radius into the chip breaker on the insert, its just going to rub which generates heat.

your rapid should always stop at least 0.02" from surface, any axis.

Little tip: it's good practice to let the machine move into home position when the program is done. In Fusion it should be a setting on the postprocess window, where you can set a retract coordinate in either work or machine space. Wonder what these are used for. If they want them to bolt to something the holes look awfully close to the wall. Hope there wasn't any miscommunication.
