The air blade housing you made for your camera seems to be doing a grade-A wonderful job. Thanks for your time and effort into making these videos for us.
Wish I was 60 years younger so that I could be your apprentice and learn from you. I don't mind the coolant. Its is just as much part of the job as the end mills and counter sinks.etc. Great video as always.
Thanks for making your awesome videos! I'm currently finishing up on building my own cnc milling machine in my garage but someday I really want to get a few Mazak machines of my own, including a Variaxis or two.
Would love to hear your thought process when making these parts especially during the cad part of the design. Kind of surprised it was mostly machining but anyways, great video as always
Yes, especially for the slanted groove! I was expecting sinking EDM as first I didn't really capture the size of these clamps and therefore having enough space for a groove cutter.
@@EdgePrecision I'd love to hear how you manage your tilted work planes on the Mitsubishi, does it have G68.2? G54.2? Did you have to add that to the control, or did it come with it? Also that machine looks like it moves pretty smooth, thanks for the vid.
@@mattnorris742 Except for setting the fixture offset/s that you are using in the cam software. The machine doesn't do anything. It is all done in the cam software. Some newer machines have what they call dynamic offsets. This machine is to old for that. Dynamic offsets can compensate for a part being off center in relation to the center of the rotary axis. So in the cam software you program in the ideal location. As if on center-line than the machine compensates for the runout.
@@poopcow32 not really most machinists skill sets are fairly limited . At this point the vast majority of people working in machine shops are glorified parts swappers
@@duck0fdeathc336 you said it yourself those aren't machinists those are what is formally known as Operators. Machinist do need to know how to set up "jigs and fixtures".
@@Juxtaposed1Nmotion well setting up basic jigs and fixtures then making 10000 of the same part is far simpler than building a new jig and fixture every part. Also most shops don’t build parts anywhere near as complex as these . Some do most don’t
Those are looking great, Peter. It's pretty amazing how much force a vise will put on a point of a part and turn it into a lever. Enough cutting force on the unclamped edge and you'll have a smashed window or face. ----Aaron
Peter, when I bought my first Kurt vise (new) 5 years ago the manual specifically mentioned this (parts off center with no counterbalance). In fact if you put a part at the edge and super tighten down Kurt says you could crack the vise casting!
@@EdgePrecision OK, I know this is totally a noob (5 years ago) machinist statement but.... At $600 for anything - I READ the manual! Now I'm "experienced" and laugh at a $600 expense, but I know that 8" Kurt you have on the tombstone is pretty good into 4 figures.
That's a very cool toe clamp. Will you be sharing the files with us. That would be a cool project to make albeit smaller for us mere mortals..... Great video! They looked much smaller on IG...
The coolant and the air are no trouble for me; there's your camera enclosure for the former and my thumb on the speaker on my phone for the latter. I look forward to seeing how these work!
Every business wants things done as quickly and cheaply as possible. But I've worked at places that have scheduled 'infrastructure update' time - allowing for engineers to work on projects they feel will help in the long run. Sometimes it's an hour or so a week, sometimes you can get a few days if things aren't super busy. It requires trust that people aren't just going slack off during those times and do actual valuable work.
@@kindabluejazz Companies with an eye to remaining viable into the future engage not only engineers, but all employees in contributing and executing improvements.
That point about vises is always true. Best to be in the center if can but a counteracting force is always an option. I rarely do work in a vise but they do tend to be a fast way to hold something.
man pete! even your clamping parts are amazing! such beautiful work. is this for the project that your customer won't let you talk about? can i ask a favor? please mention what type of material you are machining in your videos just for the knowledge of speeds and feeds. thank you pete! keep up the gr8 videos i never miss 'em
When I run the tool for the first time on a job. I check it when it comes into the spindle for the first part, visually. Than as the job is running the sound/vibration of the tool running will tell you. If it sounds or feels different the the last run. Than last the finish and dimension it is holding, if that's critical. I don't usually go to the tool magazine itself to check the tools. Unless I'm setting up new ones. Or looking for whats there to use.
Why does Op2 of the moving part have any non-straight tool paths? It looks to me like first you trace the shape of the part out but then you mill away the entire thickness (and then some) of what remains... or are my eyes calibrated wrong?
I don’t know how much they pay to power the whole shop. But I would guess it’s the air conditioners and air compressors that use the most power. Not the machines.
Id say, probably not a ton unless it’s running full load and lights out. Most spindles probably only turn 30-40% of a day, unless it’s automated. So lets say its a 30KW spindle. So about 90kwh per day for 3 hours at full load. But most likely alot less then that. So thats like $9/day in hydro give or take over 21 working days a month or something. So like $200 in hydro a month. One 1.5 ton small house ac would do 3kwh for 12-18 hrs a day. So about 36-54 kwh for a tiny one.
Great stuff thanks for taking us along . That looks like drink fit tooling ? Would you show us how it works .. ,? Is the cutter usable after removal from the holder ? The closest I come is locktite in a cutter . Thanks for your time ..
Awesome content. If I could make a suggestion show the tool name along with speed and feed when a tool is changed. I think a lot of us would like to know that.
How about offering tee shirts and hats with your new toe clamp on them? Also, when will the toe clamps be available for sale? Will you have a smaller version of it, too? Ken
Peter, what is that chamfer tool you used at the beginning of the video? I’ve been looking for a good inserted chamfer tool, and that one looked like it cut great.
@@mehmettemel8725 It looks like a Nine9 tool to me also. I didnt used their chamfer tools yet, but the engraving tools and the indexable center drills are top notch. You can push the engraving tool like crazy without rising a burr.
Great video. Out of curiosity, how much did this cost you to make? as in if someone from outside came in and asked you to quote this job design, design it, CAM it up and cut it. I imagine this would be about 1500 dollar clamps at the low end ?
That is ca little hard to say. The idea itself and the cad part didn’t take long. But making a video on something, makes it take at least five times longer. So it’s hard to say.
You've probably been asked this before so feel free to ignore. Have you looked into those spinning window things that are often used on ships to maintain a clear view no matter how much water is hitting them?
Hi Peter, I'm just getting started in CNC and was wondering about the operation at 14:00 minutes- what is the reason for contouring the non-milled area of the jaw to conform to the milled shape if you then mill it completely off? Thanks for all the videos you produce, they are great.
It makes good RU-vid content is the number one reason. Normally I would take one profile cut around for this little of material. If you try to face off say with a face mill. That is possible, but you will want to leave finish stock in on the face in the Z axis. What this does if there are large overhangs like this. Is there is a very thin piece of material that the face mill leaves, still left to remove. This thin piece often vibrates and gets pulled up into the cutter damaging it. It is better to trim it off first. With the tool below that surface in Z with a profile cut. Than face the part to size. You may have experienced this already in your work.
I have an old set of jo blocks I use if i was clamping on the edge of a vise and they come in handy for my Wellsaw horizontal bandsaw. I bought them off ebay and the lady shipped them not knowing what they were. Needless to say when I got them they were pretty dinged up loose in the box.
Hey boss, I was wondering.... Does the tombstone base that is part of the actual machine, does it rotate as part of one of the axis's? Sure, I see it all the time rotating out of the way during tool changes, but, is it a secure controlled axis while in a machining process. I am not sure I know how to ask this correctly, so it makes sense, what I am asking, So I will word it an additional way. The example of wanting to machine the curved dove tails that are on an adjustable dividing head..? Or does it only rotate out of the way for tool change clearance and when it rotates back to allow more machining processes, that table has to lock-in place, for secure machining and location identity?
Top quality content as always. Thank you for sharing. I have a question about your inserted chamfer tool...Who makes it and can it be used as a center drill as well?
Nothing wrong with the video, but I don't think you need to specify you need coolant on operations everytime. Other than that, I'm intrigued by how the assembly functions. Great video
Hello, great master, good video, I have a question, about programming the part zero where it is found in the tonstone or in the part as some dynamic zero?
This older machine doesn’t have the capability of dynamic offsets. So a fixture offset has to be set. In this video I used both the world offset witch is the center of the rotary axis and a local offset witch is set at the parts location. What ever offset you use at the machine has to be duplicated in the cam software or it won’t work. So to make that more clear. If you are using the center of rotation on the machine. Than the part program in the cam software has to be positioned the same from the center of the rotation (the world axis). For a local offset you can set the part zero in the same position as you set it at the machine.
When you are machining the excess material from the back, what is reason you cut following the outline of the part, and then mill it to the proper thickness?
Overhanging material can give you problems when facing back sides. If you cut your first side close to the parts height. Say you could not go beyond the part height on the first operation. Now when you flip the part over you have this overhanging stock. Like I did in the video. If you take just straight cuts across the stock face. Leaving a finish amount in Z. Lets say .010". Now you have this very thin piece of material overhanging the part. Often times this can be pulled up into the cutter. Or at the very least it vibrates. Both conditions can cause damage to the cutters (or endmills) tip. Now you could just take one pass around the profile standing off the part at full depth just deeper than the overhanging stock. But that could cause trouble if there are areas wider than the cutters diameter. The stock outside the cutter (endmill in this case) could be also pulled into the cutter and cause damage to the tool. This is a small part. But on a larger part on a horizontal mill gravity is pulling these fragments of material down and possibly into the cutter or falling onto the way covers, in case of heavy pieces. So I have learned from experience to avoid these issues it is better to machine away this overhanging stock first. Than face the part down to size.
Exactly how we do it where I work. Even use an inserted cutter to "slug off" those peices. Then face to thickness with a face mill. When you have various part contours and try milling to thickness without doing this, you will understand very fast. It can roast facemill inserts with that peice coming up into the cutter
nice tool clamps! is this a 4 axis CNC machine? it's amazing that the machine can change the cutting tool by itself. i didn't see much of this type of machine in the Chinese market.. looks cool!!
@@EdgePrecision This is pretty cool, is this type of 4 axis horizontal machine a very common machine in the US mold making or machining companies? we don't have this machine in our company. can I ask if it's the US brand and how much of this machine?
@@EdgePrecision Thanks for your reply, that's pretty expensive for this machine.. maybe next time you can try to think about buying this machine from China for money saving. some of my US customers buying Chinese brand injection molding machines, CNC machines for his factory.
Awww i saw the thumbnail and thought this would be perfect for our shop but then I saw the 4th axis moves and I dont think we'd have the time to replicate those on our 3 axis efficient enough to justify the time off payed jobs ☹
@@EdgePrecision totally agree. I've even got EDM at my disposal so its not a question of IF I can do it. More about how I could do it without effecting shop productivity. Maybe I'll keep it on the back burner for now. Love the look of them btw 👍
