The only way you can tap in turning mode is on centerline. In that case I turn the thread. On the Mazak I have never tapped in turning mode. If I ever did a part where I could not reach the thread with a threading bar on centerline. I think I would tap with the milling spindle anyway. Because I have never tapped in the turning mode. I’m not completely sure it does it with rigid tapping. Where the tap doesn’t need a floating tap driver. If that were the case I would never do it that way.
This channel is a national treasure for machinists and toolmakers, my great grandfather was a tool and die maker in the 1920s-1950s. I have an old vise he made from scratch I plan to refinish this winter or spring it should be a fun project. You make some amazingly complex and difficult to machine parts its awesome to watch!
Pete, I hope that one day you will be able to show us the machining of the actual part again! That is a very intense part you are machining and I sure we would all love to watch you machine that.
Mind boggling to think that the tooling costs of a job like this exceed what most people would imagine the cost of the entire job should be. You must have developed a great relationship with your customers, where they know that for the quality they are asking for - they expect to pay for the same level of attention on the tooling as on the finished part. Great content - as always.
yeah I would assume, parts of this complexity, with little bosses inside the bore with fillets on them, they know they have to take these parts to a wizard, and they know the wizard will be charging big $$ but it will be done to spec without worry.
I wonder if the designer had this method in mind when designing the part? It seems like it’s about the only way to get that corner radius at the bottom. Creative solution to a darn near impossible situation. Good job.
mark muranyi speaking from experience as a machinist for nearly 10 years, and now going back to school for mechanical engineering, they most likely don’t. The guys in my classes are near brain dead when it comes to actual creation of there designs. They don’t understand the basic concepts of rotating tools. Can’t make a perfect square hole with conventional rotating tools. We have some very basic DFMA but most of these guys don’t get it. Straight outta high school or just been in post secondary for a while they have never been to a machine shop and have watched some videos here on RUclips but don’t understand the mechanics of how parts are usually made. This is why engineering firms shit a brick when they get a quote back on some specialty parts, just cause THIS kind level of fab and setup is required for what they think is simple cause the computer said it works

Thank you for making these videos. They are truly awesome. I wonder if the genius engineer who designed this part has ever been in a machine shop.

I am a design engineer with lots of machining experience, not all "hands on" but very knowledgeable of tooling like Edge Precision uses.

These engineers developing these parts have PhD's, and are developing this stuff, and they do work with shops like E.P..

Fantastic work, love whenever you post something new. That finish almost looks like when they burnish watch components, very neat. Thank you for the time you put into this content. Greatly appreciated
With every new 'episode' this part gets more and more impossible . Peter i've said it many times already , but you really are a master of the trade . I would be honored to learn from you . If on youtube i see this kind of amazing techniques , can't imagine what it would be in person . Looking forward to the completion of the part , possibly some tolerance details too (no drawing of course)
A video about cnc and how to use it that was worth seeing. Great skill! After 22 years as operator and programmer of cnc machines, I'm not really impressed by most videos showing off machines and set-ups. This video was impressing, and I look forward to see this tool in action 😊
Peter your workmanship is amazing and admiring.One thing puzzles me is quite often you make your own tooling for the job which adds more to cost of part then again when they want something complicated as most of your work I suppose you can squeeze every dollar out of them where as my tight customers squeeze every cent out of me on basic few dollar jobs.😁
Very interested to see this work. I'm just getting into manual machining. I have a decent lathe and a 2hp bridgeport, today I made my first custom tool. I made a small fly cutter. I was pretty proud of my accomplishment until I watched this lol.
I am so worried that this type of expertise will not be passed on to the next generation. They will know how to operate the machine and the software but this type of creativity is only learned through exposure to others who are willing to pass on their knowledge. Well done sir!!
Your videos are always interesting. A lot of the time for me, especially when talking about the programming, you are way above my skill level. Self taught with machining and I have manual machines only. Wish I understood cnc programming, because it would be nice for curves and multiple milling. You sir are a master craftsman.
The complexity of these parts is mind boggling. Impossible for this uneducated amateur lathe hack to contemplate what it does. Or just how expensive the part nor the rest of the machinery it is attached too Is. Amazing, thanks for sharing.
Angle grinder used carefully leaves a surprisingly good (looking) finish! I was just drafting a shaping tool for milling machine as well. For the sake of simplicity I think it will be a rod with a hole drilled across and an old carbide end mill.
great vid, what a crazy part! very minor critique about that bandsaw info at the start: text that scrolls by is focus-distracting since you have to wait to see what it says while you build the sentence up in your head, it can be better to have text show up all at once and then go away all at once. This lets people pause to read something if they read slow or read something fast and not miss anything. I think you struck the right balance with how much machining footage you showed at how much speedup.
Creative solution to a feature that could probably have been designed a little better or at least with manufacturing in mind as someone else pointed out earlier. But then again we wouldnt have been treated to this video, on how to be solution oriented and find ways to overcome. Thank you!
Que grande eres..y que poder resolutivo..da gusto ver la capacidad que tiene tu mente..gracias de verdad por hacernos un poco menos ignorantes..un saludo
I make broaching tools all the time it's not that hard ph horn REV from italy inserts are already too expensive I don't have $300 sometimes $500 for a holder so I'll hack something myself
Pretty Slick there Peter. Necessity is the mother of invention. Make those engineers pay for what they draw on a screen. Not actually knowing the difficulties of machining such features.
Yet another crazy part. Makes me wonder if Peter is giving kickbacks to the engineer so he will design parts that only Peter can make? ;) I used to like solving tricky problems, but I think if I had to make all these parts I would just lose it.
wow, you must be the old school machinist make it to modern machine shop. not too many modern machine shop want to make tool, they make tool to win bid quick, then ...... it. Thank for showing us these trick
Most of the time I see you make medium sized parts on this CNC. Parts that would fit on a much smaller CNC. How come yours is so big? Would it not be cheaper to run a small CNC and get the wear there? Does the size of the machine affect the cost of operation? I am just curious about why you have such a big machine whereas others have one that is half the size.
Can you do a video on the accuracy of your touching off method vs a height gauge. Your work is so precise and I feel that touching off can be so subjective to pressure and feel. Love your work. Its a master class every time.
I can tell the difference between one click on the hand wheel. That would be .0001". Because the dowell pin is hard there is no give and it's round shape lets you approach the setting gradually. With a shim/feeler gauge you can not get the same feel. Also you have to know the location of the surface you are using as a reference accurately. A height gauge can be equally as accurate depending on its use.
Thanks for showing the broken flute! Makes me feel normal :-) If you can finish the pass with a single flute, could you feed 3x faster with three flutes than what you do here? (Not that it matters much for a one off!)
PETER SOMEDAY YOU MIGHT WANT TO EXPLAIN HOW YOU DESIGN TOOLING. OF COURSE ITS EASY FOR ME TO SAY THAT. YOU PROBABLY WILL NEVER HAVE THE TIME. THANKS FOR ALL YOUR VIDEOS.
Thanks Doug, there really isn’t a process per say. I always try to use standard tooling when possible. I look at the part and what I have available to me. If that won’t do the job I design something. And this is important. To do it with what I can afford or what I can build. There are many ways to do things. These are the way I come up with. I don’t contend they are the best or even the right way. It just my way. I present them for everyone’s interest and critic.
budzab all I have to do is take a Capto turning tool holder that’s designed to hold a square shank. Mount it in the adapter in the C axis. Than indicate on it. This will give me the orientation.
I wonder how many times do you end up putting this same part in the machine to do all these different steps? Doing that really adds to the chances of a scraped part. Thanks for sharing your custom solution. Charles
All the ID work that runs concentric to the OD on this end will be done in one operation. Even the holes and ports you saw in the model. Including this key and the one farther in the bore. These parts have many operations it’s unavoidable. I just have to be careful about misalignments.
can you elaborate ? I am not a machinist, was the part technically flawed ? too time consuming to produce ? oh and by part, do you mean the tool he made or the actual part with the keyway thingy he needed to produce ? thanks in advance dimitar
Sorry, i meant the part being machined. The tool looks perfect. As for the part, having an integral key is difficult enough but there is also space behind which might not be too difficult to machine with the proper boring bar but it is still too complex. Any indexing or moment transfer needs could have been met easier i think (even not knowing the restrictions i would think that)
Great solution. One question. Why did you not just turn most of the shank to base dia and leave the pocket portion for milling. Like a "hammer head shark" Did it really need the extra material to aid rigidity. I notice you were content to leave front square and flat. Were you not worried about swarm falling down and being crushed between shoulder on job and tool?
I guess I could have done it that way. It would have reduced the machining and also the strength of the tool. The tool isn’t really round it’s more oval shaped. I will be running high pressure coolant thru the tool and it will be stoping a good .187” from the back shoulder. I don’t think there will be any shaving problem.
What other controls have you used Machining wise ? Favourites? Pros and cons ? I’ve been pretty much fanuc and heidenhain. Each have their merits. I’m interested In your opinion.
my understanding is heidenhain is the "smartest" of it all everybody loves fanuc it's basically universal i was a okuma operator for years but now i find mazatrol to be the best the easiest the conversational GO TO control what machines are you running?
Seems to me the better solution to the design intent on the clients piece would be just like the capto tool shanks you are using. You have far more patience and tolerance than me. I would have taken a big stick and beat some engineering savy into the designer.
So right now I'm in the middle of learning about wrapped tool paths. I see that you didn't use one when you were roughing out the clearance areas of the tool. Was a wrapped tool path the option you passed up on? Specifically I mean a tool path that has your endmill 90° from your z axis and the path would mostly use the Y, Z, and C axis? Is that the path that you said it harder to program?
Do you think is possible to make a similar tool for a normal milling machine? Like your horizontal. But something that would not hurt the spindle bearings. The programming is possible in Esprit.
Yes I have done this on my horizontal mill as well. The load on a shaping tool will not hurt the spindle bearings. As long as you don’t take to large a cut. On a normal machine you will need something to hold the spindle fixed/ orientated. Esprit doesn’t have a cycle for this kind of machining. It has to be done manually.
@@EdgePrecision Its 25MnCr steel or similar, its made so that you can induction harden areas without destroying the Capto, it doesn't get super hard but around 52 Hrc.

That fillet is either a mission critical feature designed by an extremely experienced engineer or a useless cosmetic feature designed by an intern.
"Hey Tim, did you remember to remove all those bullshit cosmetic edge breaks before we sent out that part model?....No? Oh well....fuck em'"
It's amazing watching you develop your own tooling. So much planning is involved for the products you machine.
Are you an employee or owner of this company
Luv it. “doesn’t matter, I just don’t want to look at it”
Mind boggling to think that the tooling costs of a job like this exceed what most people would imagine the cost of the entire job should be.

These videos are like machining crack. I just can't get enough.
2nd time I've watched this a year apart ~ very compelling.
I do like that pattern on the tool. I'm glad you kept it.
I wonder if the designer had this method in mind when designing the part? It seems like it’s about the only way to get that corner radius at the bottom. Creative solution to a darn near impossible situation. Good job.
I also wonder about this. Do the engineers know how difficult it is to make these?

Awesome! Love your vids! Learn so much from you!
Nicely done!
Thanks for the video.
Cool tooling, great video!
I love these custom tool videos. Would love to make my own indexable cutters.
ive never even thought of a mazak being used as a shaper before! excellent video ...thinking outside of the box
quote "the only thing you cant make with a shaper is a profit" looks like that myth is debunked
looks so great!!
Angle grinder used carefully leaves a surprisingly good (looking) finish!

You need to borrow "this old tonys" rotary weld table to show off your awesome homemade tooling! Haha!
That would be cool!
Nice job. Something to be proud of.
On first look the thumbail looked like a huge thread cutter to me due to the ordinary finish. Great Job Again Sir
super interesting. How you think this stuff to do a part is truly ingenious.
Good stuff as always Peter!

i want to see this tool in action!
Your mashine is pritty amsing. I have a small lathe. From China. 5 inch Chuck. And I'm not sure? 2 foot bed?
But I enjoy and am happy with it. M
Peter is the machinists' machinist. :)
Very interesting Peter. Really cool how you go about these jobs you do. Does a part like that take long to quote?
If you change the safety clearance in your cam output the machine won’t move away for so long. You can set a safe distance from diameter for x y z.
You make some amazing tools peter!

@Edge Precision It would be a good idea to make a flat on that Capto adapter to level the C axis with spindle orientation for similar tooling projects
budzab all I have to do is take a Capto turning tool holder that’s designed to hold a square shank. Mount it in the adapter in the C axis. Than indicate on it. This will give me the orientation.
I wonder how many times do you end up putting this same part in the machine to do all these different steps? Doing that really adds to the chances of a scraped part. Thanks for sharing your custom solution. Charles
All the ID work that runs concentric to the OD on this end will be done in one operation. Even the holes and ports you saw in the model. Including this key and the one farther in the bore. These parts have many operations it’s unavoidable. I just have to be careful about misalignments.
MUM, you told me never to hold a milling cutter in a 3 jaw, Peter is doing it so it must be ok!
Not bad, nice video unlike many, I perform this routinely, almost daily....it's having "finesse", which many do not!
If I designed a part like that, I would get flogged.

Do you ever offset the threaded hole for the insert screw to help the insert "pull" into the seat by just a few thousandths?
Yes about .005 toward the back walls.

I don't know if you already knew this, but i noticed 10:26 - 10:27 that you didn't have your capto markings aligned between the holder and the blank
Very nice.....Top.....
Seems to me the better solution to the design intent on the clients piece would be just like the capto tool shanks you are using. You have far more patience and tolerance than me. I would have taken a big stick and beat some engineering savy into the designer.
So right now I'm in the middle of learning about wrapped tool paths. I see that you didn't use one when you were roughing out the clearance areas of the tool. Was a wrapped tool path the option you passed up on? Specifically I mean a tool path that has your endmill 90° from your z axis and the path would mostly use the Y, Z, and C axis? Is that the path that you said it harder to program?
I modeled the part with flats on the OD. If I had modeled it with cylindrical surfaces a wrapped tool path would have been the way to go.
Why not use tail stock to support whole part when machining profile outside? Wouldnt that reduce vibration and extend endmill life?
Yes but on this big machine the tail center can't get this close to the chuck. The part has to be at least a 20" projection from the chucks face.
Do you think is possible to make a similar tool for a normal milling machine? Like your horizontal. But something that would not hurt the spindle bearings. The programming is possible in Esprit.
Yes I have done this on my horizontal mill as well. The load on a shaping tool will not hurt the spindle bearings. As long as you don’t take to large a cut. On a normal machine you will need something to hold the spindle fixed/ orientated. Esprit doesn’t have a cycle for this kind of machining. It has to be done manually.
Thanks as always. What material is the tool? You prolly said but I keep missing it on the video.
The tool is a Sandvik machinable C8 capto blank. What ever they make them out of. Some kind of steel.
@@EdgePrecision Its 25MnCr steel or similar, its made so that you can induction harden areas without destroying the Capto, it doesn't get super hard but around 52 Hrc.
@@master8laster49 That makes sense. The Capto end can be filed but is noticeably harder.
