It must be a great feeling to finally, after all this time of building and learning, and all the doubters, to have a job that could show how CNC can be valuable even to a small job shop without it needing to be for a large batch, and know you have the skills to knock it out quickly. Cool journey, Adam.
I will admit, the cnc stuff is growing on me. But, I would LOVE to see this particular operation done manually. Mainly because I can’t afford a 100k machine
Sweet. I have a $30k machine in my garage that could do the same part. There are CNC machines available that are $15k that could do that same job. So these machines aren't quite as unaffordable as you may first think.
@@RedBear345 You can just join the club :) I work with a lot of people that discover that really good CNC equipment can be had for a lot less than they imagined. In the last 10 years, there CNC software and machines have more affordable options for the people interested.
One way to do a radius like this on a manual mill is also to mount the part on a rotary table and cut it with the side of an end mill. It takes a while to set up but works pretty well once you’re there. Probably faster than freehand roughing it then setting up a boring head 😊
@@ramanshah7627 This is about a 6" radius curve needing a 15" RT, what do you do when it is a 12" radius curve? CNC will do both and more. Learn how to do it once with CNC and then you know that you can do any other radius.
@@martinconnelly1473 No harm no foul, you're right, and it's good logic. Cutting a radius where the radius approaches infinity is a killer app for a CNC mill. I was just responding to the initial commenter. I learned/did all my machining during my Ph.D. to make components for our physics experiments, and we only had access to manual machines. That's when I did the rotary table setup I discussed (to make a brass counterweight that mounted flush to the outside of a big tube). Now I'm just a civilian and don't have anything more impressive than a drill press in my basement. I'd happily learn CNC, but there's nearly zero chance I'll ever have the chance to operate a CNC machine. But I'm still eager to do good things with what I do have.
Dude, I'm 3mins 58 seconds in and already super impressed on how this video looks, and how your talking about what your doing with some gusto. Good for you buddy keep learning it's making great videos.
OK I gave everyone a thumbs up👍🏽 I do miss the old a bomb, bare knuckle, fighting material, flipping levers ,turning handles 😂😂 the new shop is definitely out of this world a dream shop for anyone even me❤
I'm proud of you describing a manual process to cut this and then switch around and say "I'm going to use the Milltronics" which means that you are getting more comfortable with CNC and really taking an effort to learn new things.
Adam, great job and keep it going! The mixed machining content is great! (In my opinion). Like to hear you going through the CMM thought processes, errors and all. Its real!!!!
Adam, this video made me very happy for you. It’s been a long road, but seeing your confidence and success with this little job is heartwarming. Thank You for being so honest in showing your work and what it’s taking for a highly skilled manual machinist to leap forward with both feet. Kudos.
Adam, Would you consider doing a comparison video of you doing the same job using manual machines only? Not to prove anything - just to satisfy a curiosity…. It would be very interesting to see the time difference between CNC, and manual machines - same Machinist, different machines. ❤ all the content you produce, and I am happy that you are successful and enjoying your new shop!
Adam - Nice job. Nice to see you not hesitating to *add* CNC to your repertoire of skills. If you were at the home shop I could just as easily have seen you run that web-reduce side on the shaper... just because it would be fun to do. Adam likes big chips! ;)
Look into prototraks their conversational programming is really nice. All the benifits of a manual, with quick cnc programming. The 3d surfacing gets a little more complicated with conversational tho
LOL, I feel like a barbarian, as I thought, and probably would have, cut that curve on the bandsaw, with a bit of filing, followed by a visit to the polisher!
I love your content and love to learn new things like CNC usage, but I started watching your content to see your amazing manual machine skills. With content like this it would be amazing to see you do the part first in the CNC, then in the mill, and finally the easy way in the lathe.
I like your use of the word 'elegant'. It seems that way to me, and in a general way I think going for the elegant solution elevates the level of anyone's work.
@@soundgod06 He didn't have a backside chamfer tool and no time to order. The job came in late that afternoon, and was machined the next morning and picked up by lunch.
Interesting to see how that part was machined on the CNC. I would have sawed the radius and excess material close to the line on my bandsaw leaving a little for finishing. Probably about 30 minutes total.
Another nice, relatively simple, project! I learned my drafting the old-fashioned way: Pencil on paper, then ink on vellum. Never got into CAD either. We had Intergraph at Southern Tech (SPSU) but by the time I was FINALLY graduating with my second MET degree I was so burned out after so many years (13 all told) of working full time and taking night classes I was NOT going to take one more class! I HAVE just got Fusion though and I'm looking forward to playing with it (even though I'm retired from Engineering as a job) ...
Similar experience here. Learned drafting on the board in high school and continued in college. CAD was terrible back then and I really despised it and thought it took the artistry and skill away. Now that I have CNC milling and lathe capability in my home shop, CAD is a must-have tool. I now model in Solidworks and CAM using BobCAD. Never fear however, I still have a board in the shop, just for the simple stuff!
@@charlieromeo7663 I still have a board. Fantastic almost free one. I bought a drafting table from work many years ago for $80.00. Huge thing, flat no tilt. BUT it had a K&E drafting machine on it. I kept the machine and sold the table alone for, yep, $80.00! Later on at another job we got a bunch of office furniture and other things, among them a nice tilt table which I bought for $20.00. I put the K&E machine on IT and as I type this it's 10' away from me! 😁
Adam, have you considered applying something similar to RainEx to the inside of the glass doors and mount a air hose nozzle to blow air across the glass on the inside to clear the water droplets. This way you wouldn't ever have to put cameras inside the machine.
This is what clear view screens are for (ave fitted one to his cnc a while back, they also use them on ships), you don't want to mix other chemicals into your coolant i don't think.
I'm seeing a few critical comments. I think Adam probably could have knocked this out in 5 minutes on a manual mill but wants to use this as a chance to improve his skills with the CNC. If he always goes with what's comfortable, he'll never learn.
I don't disagree but you're missing my point. One day a customer will want 200 of those brackets and now instead of feeling anxious about not doing it before, he'll jump right into it and possibly differently because he's learning a lot. He now has information about how long programming and setup takes and can factor that into a decision to do it old school or cnc. This was an investment into himself
@@Tezza120 if he gets an order for 200 then he will definitely want to revisit the orientation he uses. Ignoring the traditional proven methods will bite him 200 times.
I feel like your Y axis was off slightly on the radius, too, and that's why you had the step. It doesn't matter for what it is, just another day learning and doing.
If I had to make that part manually ...it would be done on the band saw and bench grinder. Which is not to say thats the right way to do it, but thats how I would end up doing it.
Not a bench grinder but an oscillating spindle sander with a coarse grit sleeve to the line. Aluminum sands like hardwood, but you would be amazed how many woodworkers do not know that and have me machine things like this for them.
@@37yearsofanythingisenough39 Love my Triton POS spindle sander for Timber and Ali 👍My 14" Timber bandsaw also does great on Aluminium. For Long Straight Cuts my Cheap Tracksaw with the 'proper blade' eats ALi Checkerplate at 2 or 3mm. Not giving up my CNC mill however 😜
Bandsaw makes quick material removal(plus the cutoff could possibly be saved for customer to use if desired instead of turned to chips). Same with cutoff on straight side.
Automation does ease up things but the down side is reall hand work that shows expertise and experience. Well we have to look live with that. I still wonder that the first lathe made was all hand made.
My thoughts exactly. Just clamp it on one of the sides so the other is hanging over the vise and then sidemill it. The material looks thick enough to get away with it. Afterwards you could even just flip it around and not even have to reindicate.
@@CatNolara Exactly. 15 mins on a prototrak, I cut per side with a fine pitch rippa. Why use the end of an endmill on Aluminum where chips can get clogged in the flutes worse still a ball nose cutter where there is hardly any chip gully at the point. No need to use any special jaws on the vise. As you say no need to indicate for the flat side. If the straight line program is longer than the part then loaded anywhere within reason will be ok.
Yep. 2d adaptive to rough, 2d contour to finish. 2d chamfer the top edge then use a thread mill or back deburring tool to get the bottom edge all in a single setup. This is a 20 minute job including the programming.
Try to get your adaptive pattern for the step cut on radius to run as an oval. Your losing time with the Z axis return between each cut. Feed rates are also low based on spindle load.
Since you asked, as a business owner I would go back to the client and see how critical that specific radius is. Ask what’s the purpose and try and get pictures from them. Someone may have just drawn that radius on there without thinking too much. I’d try and see if it could be milled normally with a large end mill. Like to mill out a pocket instead of a radius. Would make it so much easier and cheaper for the client. As we all know, the customer is always WRONG!
You cant clamp it in a vise that way, personally I would clamp it on the table with a piece of 1/4 inch plastic underneath and get both sides in one shot
@@PeterRakowski Of course you can clamp it in the vice that way, one leg goes down between the jaws and the other leg is horizontal floating in space and gets the radius cut in it!
Hay Adam for your camera set up maybe try forced air on the camera lens while it is cutting to blow the cooling fluid off the lens. Give it a try and thanks for the great video
Climb milling is only a problem if the leadscrews have significant backlash, like with ACME threads. CNC machines usually use ball screws which have effectively no backlash, so you can climb mill with all the advantages and no drawbacks.
Quick question why don’t you send your g28 home z and y at end of program m30 instead of having your tool right above part and y way out there? Where you have to jog everything back up and towards you?
Have you ever thought of getting a Spinning Viewing Port for your CNC, if you watch AvE he fitted one to his CNC and it works great, by spinning it fling the coolant away keeping your view clear for you or your camera :) love your work. Thanks
You're learning a lot in a very short period of time. Congratulations to both you and your teacher! Using the Renishaw probe was elegantly and efficiently done. I would suggest that you do something similar for the second setup, because the width of the chamfers is sensitive to the placement of the part. I don't know how to do this in CNC, but basically the probe program produced a block of three numbers that represented your reference position. Any other point on your CNC system could also be represented by a block of three numbers in the same form. I suspect that you are using some special CNC memory for this. However, I expect that the CNC mill also provides some memory in which you could store a copy of this block. Again, I expect that a CNC program could be programmed to "read" a stored memory block. If so, then I think that it would be a good learning experience to write a second CNC program that reads the numbers and checks for errors. This second CNC program could produce a result code, such as zero for OK, one for "material too thick", two for "needs tramming", etc. For repetitive jobs, especially with expensive starting materials or delicate tools, this could save you a lot of aggravation.
Everything you said is where fixturing and soft jaws come in. The machine stores the XYZ position of the setup in the control as a work offset. You can have multiple work offsets - say one for OP1 (G54) and one for OP2 (G55). Probe your first part, and then set a vice stop for subsequent machining. This will allow placement of the next piece of stock without having to reprobe it every time. Same thing can be done for OP2, or if part shape requires it just mill a set of soft jaws that matches the part contour and probe either a feature machined into the jaw or a thru hole in the part that you machined in OP1 if it has one. Of course the program will need to call the correct work offset for the operation it is doing. But in general if all you're doing is setting your work offsets with the spindle probe then it is extremely underutilized precisely because the steps defined above render it unnecessary.
@@cskovach , nice comments. However, Adam often takes jobs where only a few parts are requested. In this particular case, I could see his customer wanting similar brackets, but with different cutout shapes. At a higher level, I am aware that I come from software engineering rather than CNC machining. I have a lot of respect for machinists, and am trying not to use specialized terms like subroutines and data structures. I have done some woodworking, where most of us try to follow the advice of "measure twice, cut once".
@@stuartschaffner9744 if you have to make similar but different parts you can either write a generic macro with input parameters to allow for some flexibility, called as a subroutine within the context of a larger program or you can just write a different program specific to that part. There isn’t really a need to make it more complicated than that.
@@cskovach , I agree. I didn't want to use software-engineering terms like module and subroutine until I heard someone from the CNC community use them. My only quibble with what you said is that often customers for a specific part on a specific day might want similar parts on future days. In particular, a mounting plate often has some properties determined by what item is to be mounted and other properties determined by what that item is to be mounted on. In the current example, Adam discussed how certain aspects of the adaptor plate were determined by his customer's products but other aspects were determined by what could get in the way. If the modularity of the program reflects the modularity of the customer's needs, it will be easier to modify the program the next time the customer has a rush job like this.
Hi Adam! just a quick question for you (or anyone else who might know the answer) what are the coolant hoses you're running that are shown at 6:11??? Ive been on the hunt for something better than Loc-Line for a few months and these would be perfect for my application!!! Thanks in advance!!!
The customer supplied him with some numbers. The arc was to end 1" from each side. The quadrant of the arc needed to be 1-1/8" from the front edge of the angle. Using Fusion to draw in an arc and dimension that with those requirements, the arc was created at the correct size. Which was a radius of 5-5/8".
Late 70's - mid 80's while a teenager I helped out my Dad stuccoing houses when I wasn't in school. I broke my ass for just $20 bucks a day and I thought I was rolling in the money! Gotta love that cheap labor, huh?
Stopped at 3:40 to post. Clamp 7/8" flange in the vice, 2d contour the 18" radius as OP 1. Turn the part, buzz off the 7/8" flange as OP 2. I guess if you're using this as a means to practice Z-contour milling for future die-type jobs, then cool. Just seemed like a lot of effort to machine it that way when there are more direct options.
He wanted to do it this way so he could chamfer both sides of the cut. Plus it was a good learning experience. And it was still pretty darn fast to do.
It must be a great feeling to finally, after all this time of building and learning, and all the doubters, to have a job that could show how CNC can be valuable even to a small job shop without it needing to be for a large batch, and know you have the skills to knock it out quickly.

Hi Adam, does Milltronics make a spinning glass window like on ships to be able to see the milling process?
The machine sure was singing a pretty song when it first started cutting the radius....
Hacksaw and file 15 min job!
In my home shop I use a hack saw for a radius cut.
That will also build your character 😂

You could clamp it in long length of your workpieces on vise and finsh it all in one setup with an endmill and less time

Great job that was fun to see you master this process
Hey Adam .!! - Cnc is miraculous - but you could have knocked that out in half an hour with a bandsaw and a file/ flap wheel.!!! …👍💪🏻💪🏻💪🏻
Glad to see Adam's confidence growing. Manual milling has its place but CNC milling needs to be learned for any machinist to have a future.
That is not untrue at all...as someone with zero machining experience I completely disagree with my statement.
I really want to see him set up multiple stations on that FlexCNC ..like 3 or 4 identical parts .. and just let the machine go to town
I love you channel and I really like your intro music. Can you tell me where you got it. I want to hear more of it. It’s super relaxing.
I think it's from a free for use library like the picture ones. Budget Buildz has used the same music a couple of times lately also.
Did you program this on the conversational control or did you program it in CAM? Would’ve been interesting to see how you programmed the first op.
He did it in Fusion CAM.
You could easily used the ball endmill to make the chamfer too.
I like it. That shows good lateral thinking combined with experience and the blindingly obvious. Great comment and tip for the viewers.👍👍👍

probably to practice programming, or because you would have to set it up again to chamfer the other side
You cant clamp it in a vise that way, personally I would clamp it on the table with a piece of 1/4 inch plastic underneath and get both sides in one shot
@@PeterRakowski
Of course you can clamp it in the vice that way, one leg goes down between the jaws and the other leg is horizontal floating in space and gets the radius cut in it!
True that would work lol, I still like my way better lol
@@PeterRakowski Your boss would not like it that way beings it would take atleast twice as long probably longer.
Hay Adam for your camera set up maybe try forced air on the camera lens while it is cutting to blow the cooling fluid off the lens. Give it a try and thanks for the great video
That was just cooler than the other side of the pillow. I enjoy the mix of new school and old school in your content. 🥸👍👋✅
More and more traditional mechanics began to like CNC, and tried to use CNC to reduce the workload
Alumium!
Nice, I would have cut the excess off in the bandsaw, save on cutting time and also get to keep a bit of aluminium for something else
It seems to me that a lot of the cnc milling is done "climb milling" does it no matter with these machines?
Climb milling is only a problem if the leadscrews have significant backlash, like with ACME threads. CNC machines usually use ball screws which have effectively no backlash, so you can climb mill with all the advantages and no drawbacks.
Another fine job Adam your the man.😊
Quick question why don’t you send your g28 home z and y at end of program m30 instead of having your tool right above part and y way out there? Where you have to jog everything back up and towards you?
Good for you. I didn't think you were gonna CNC that for a minute!
Have you ever thought of getting a Spinning Viewing Port for your CNC, if you watch AvE he fitted one to his CNC and it works great, by spinning it fling the coolant away keeping your view clear for you or your camera :) love your work. Thanks
Smart job. Reminds me of chomping a slice of watermelon 😂
You're learning a lot in a very short period of time. Congratulations to both you and your teacher!
Using the Renishaw probe was elegantly and efficiently done. I would suggest that you do something similar for the second setup, because the width of the chamfers is sensitive to the placement of the part.
I don't know how to do this in CNC, but basically the probe program produced a block of three numbers that represented your reference position. Any other point on your CNC system could also be represented by a block of three numbers in the same form. I suspect that you are using some special CNC memory for this. However, I expect that the CNC mill also provides some memory in which you could store a copy of this block. Again, I expect that a CNC program could be programmed to "read" a stored memory block. If so, then I think that it would be a good learning experience to write a second CNC program that reads the numbers and checks for errors. This second CNC program could produce a result code, such as zero for OK, one for "material too thick", two for "needs tramming", etc. For repetitive jobs, especially with expensive starting materials or delicate tools, this could save you a lot of aggravation.
Everything you said is where fixturing and soft jaws come in.
The machine stores the XYZ position of the setup in the control as a work offset. You can have multiple work offsets - say one for OP1 (G54) and one for OP2 (G55).
Probe your first part, and then set a vice stop for subsequent machining. This will allow placement of the next piece of stock without having to reprobe it every time.
Same thing can be done for OP2, or if part shape requires it just mill a set of soft jaws that matches the part contour and probe either a feature machined into the jaw or a thru hole in the part that you machined in OP1 if it has one.
Of course the program will need to call the correct work offset for the operation it is doing. But in general if all you're doing is setting your work offsets with the spindle probe then it is extremely underutilized precisely because the steps defined above render it unnecessary.
@@cskovach , nice comments. However, Adam often takes jobs where only a few parts are requested. In this particular case, I could see his customer wanting similar brackets, but with different cutout shapes.
At a higher level, I am aware that I come from software engineering rather than CNC machining. I have a lot of respect for machinists, and am trying not to use specialized terms like subroutines and data structures.
I have done some woodworking, where most of us try to follow the advice of "measure twice, cut once".
@@stuartschaffner9744 if you have to make similar but different parts you can either write a generic macro with input parameters to allow for some flexibility, called as a subroutine within the context of a larger program or you can just write a different program specific to that part. There isn’t really a need to make it more complicated than that.
@@cskovach , I agree. I didn't want to use software-engineering terms like module and subroutine until I heard someone from the CNC community use them.
My only quibble with what you said is that often customers for a specific part on a specific day might want similar parts on future days. In particular, a mounting plate often has some properties determined by what item is to be mounted and other properties determined by what that item is to be mounted on.
In the current example, Adam discussed how certain aspects of the adaptor plate were determined by his customer's products but other aspects were determined by what could get in the way. If the modularity of the program reflects the modularity of the customer's needs, it will be easier to modify the program the next time the customer has a rush job like this.
Hi Adam! just a quick question for you (or anyone else who might know the answer) what are the coolant hoses you're running that are shown at 6:11??? Ive been on the hunt for something better than Loc-Line for a few months and these would be perfect for my application!!! Thanks in advance!!!
U could use a rotary table.
That would be a pretty big table though.
How do you determine what that radius is?
The customer supplied him with some numbers. The arc was to end 1" from each side. The quadrant of the arc needed to be 1-1/8" from the front edge of the angle. Using Fusion to draw in an arc and dimension that with those requirements, the arc was created at the correct size. Which was a radius of 5-5/8".
I saw this same video in the past couple of weeks. Maybe on Facebook?
guess he puts out videos on FB and Instagram quite regualry, several times a week,
IMHO, one setup in a CNC, using a large diameter end mill and rough the radius and edge cut, then using a second pass finish the two cuts and chamfer.
table saw and a rotary table
Late 70's - mid 80's while a teenager I helped out my Dad stuccoing houses when I wasn't in school. I broke my ass for just $20 bucks a day and I thought I was rolling in the money! Gotta love that cheap labor, huh?
how much did you charge?
How much do you make an hour?
@@MechanicalAdvantageWhy?
@@MechanicalAdvantagehow long did it take you to write the program for this?
@@MadmanJimbo I didn’t make the program for this.
@@MechanicalAdvantage oh I didn’t know you had employees. Simple stuff so I guess they can handle it
Stopped at 3:40 to post. Clamp 7/8" flange in the vice, 2d contour the 18" radius as OP 1. Turn the part, buzz off the 7/8" flange as OP 2.
I guess if you're using this as a means to practice Z-contour milling for future die-type jobs, then cool. Just seemed like a lot of effort to machine it that way when there are more direct options.
He wanted to do it this way so he could chamfer both sides of the cut. Plus it was a good learning experience. And it was still pretty darn fast to do.
I wondered that too. Dang, I thought I was fancy by having a Haas TM1 in my home shop, but that probe really is just cheatin’ !
cool
Couldn't you have milled that radius side-on if you'd clamped it at 90 degrees? No need for a ball mill then.
its a chord of a circle
