Everybody can do Op1. Its following fixturing, setups and operations that make or break you. Could you guys dedicate more videos to educating people on that sort of stuff? Its where the critical thinking about problem solving skill come into play. That's a really neat looking part though. Would love to see it finished.
I'd put this down inside a pocket. Some ID clamps on the end diameters, and some uniforce clamps along the length. Thats what i'd do.
I understand this is just a programming demonstration and I don't want to come off critical, but warpage, hole alignments and tolerances are always something that has to be considered. Working such a long thin part in a tab-frame has been the preferred method to allow even stock removal and control warpage, maintain tolerances, limit vibration and tool chatter
.
Yea i probably would never finish anything on that first op. I usually do a "qualify" operation to square up edges and face off the scale. Even then i would probably just rough some of the features.
Always start with the easiest way and only add complexity if needed.
Im sure they get a good part just fine vicing it.
Great video productions and sound levels. Music was on point and young spoke clearly and well. Good tips.
nice vid :) I like it
I was positively surprised that when you released the part from the vice it didn't spring or bow
Wow Beautiful work love to mill learning lots in Mill. You have the best place to work!
I have been programming with Mastercam 15 years. I have tried a few other cad/cam but like Mastercam the best. I am a one man operations programming machining do it all.
Thanks for this video!👍👍👍
Amazing nice job..!!!
That is a very informative, expert, professional video that we can all learn a lot of machining complicated part. Thank you so much.
Would have loved to see what kinda offsets you guys use when stepping over from a larger mill to a smaller one for the corners
The explanation is very detailed ..👍 Very easy to understand by people who can CAM ..
but I don't understand😅
Can you show the second op removing the remaining stock?
He flips the part and screws it downs in a vise with remaining stocks lowest point sitting 2mm above jaws or so. Tighten jaws hard enough to hold the part, but not too hard to not deform it. Then you remove that stock with facing mill moving lengthwise down to a final thickness, afterwards you can center the part if further operations are required. But yeah, depending on stocks and final parts "features" many problems can occur. Sorry English is not my first language.
I'd love to see the distortion in that part after removing the screws after the 2nd op.
Must be like a banana.
@@neilwoodward7336 what are you smoking? There is no "distortion"
@@ShitThatsMyn
When that part is released from the vices, there will be massive distortion.
@@ShitThatsMyn it depends, how tight are the screw , alluminum it’s easy to deform
And depends which tolerance you want
I love you man!!!!!!!!
Great video. Dynamic milling path creates huge size of file, how do you control if need to minimize that size? Thank you.
It's a really beautiful CNC part.
But I want to know more information.
Could you provide the deformation state of this part when the first operation is done?
Đỉnh thế các anh 🇻🇳
Thank you!
Still learning but a gorgeous part from a non-technical viewpoint.
You guys use Fusion 360 too (think I saw it in an older video) or mainly Mastercam?
Background track is lit🔥
i have no clue what you were saying, but the part looks awesome!
As I or we follow all the Academy's video's, be nice if your company shirts had your name on them, first only. That way one day if we come for a tour, would be nice to put a name with a face and let team know personally how much we appreciate all their effort's in teaching us through the Acaademy. Thx, and the 9 axis mill in action is awesome,,,Bear
Love the new knowledge i have gained from watching this channel, can u guys recommand me to a good supplier of aluminum and inconel.👍
Nicely done. It's complaining at high level, but I would give a bigger angle by the helix in the pockets and double the feedrate on the drill. Nevertheless, really good job!
I have to ask, can you retract in any other way than along axis on a 3 axis VMC?
With the (Multiaxis) parallel toolpath set to 3 axis: yes (in total you've got 18 option to retract yout tool with this toolpath)
I can porgam with mastercam but i'm not an expert, but i think this is only an option with the Multiaxis toolpaths.
can you show second op?
Nice
What arc filter settings are you using for that amazing finish?! I experience faceting around curves
are you outputting true arcs or arcs as lines?
2:20 the problem with this toolpath is, it doesnt always hit all faces even though, they are completely accessible to the tool. Just like in this moment at the center of the screen, i can see a large portion where the tool didnt cut.
Or it hits the ones its not supposed to because mastercam doesnt know what cutting inserts are.
Generally while this came out very well theres still potential to save time. The 2nd time calulating the raw material was completely unnecessary afaik, he could have just used a contour to only mill the insides
Greetings from Germany.
I am currently in year 1 of 3.5 years in an apprenticeship with Miele (I am going to be a tool mechanic).
It is my dream to find a job in the Usa and become a citizen of this amzing country.
God bless America.
Boom
Do you measure the dimensions of raw material before programming it?
I always do it (in this way no surprises with roughing)
How bent did the part come out though?
Honestly inventor hsm or fusion 360 seem much more user friendly.
They might be but people like me who have been using mastercam for over 10 years don't like the handholding software. Haha.
Until you need any significant level of control then Mastercam blows fusion out of the water in every aspect.
I used fusion 360 for school, but mastercam at work and in the shop. I found fusion was a lot more beginner friendly and once you learned the program and keystrokes you can make your away around pretty good but MasterCams attention to detail and ability to do certain things fusion can’t I think is why people tend to lean towards it.
@@daytona81 Writing the G-codes gives you an even better level of control.
mastercam gives you a great control in each operation especially complex multiaxis toolpaths
Now finish op2 with a 50 micron flatness and 25 micron parralel to the top face of op1. This is the kind of knowledge bthat needs to be spread especially on a part like that.
I think just using the damn metric system already would be a huge improvement. Dealing with suppliers from the US is a pain.
@@franciscoanconia2334 hahaha yes it is pain in de ass :D
I can easily do 25 microns on that part. magic is in fingers.
@@ShitThatsMyn its definitely doable but the skill is in work like that and achieving those tolerances. I think just showing the Op1 and not the more in depth process is missing a trick.
How to process the back side?? Jig ? Or vise?
Custom soft jaws
You ever do hard turning?
How to mill the other side This is what i always wanted to know
Pocket milling is missing from the video
Autodesk Inventor CAM looks a lot easier to program. I’m wondering why y’all use Mastercam instead of inventor CAM?
Mastercam is dedicated to ony maching, Autodesk is really for designing. I have programed with Fusion, and it doesn't compare.
And backside?
Soft jaws is my guess.
@@kyleparrish532 Yeah, I know, but I thought there was a video about it. 😬
@@kyleparrish532 Soft jaws over this lang? Is not so easy. There is no 100% tension .
And you definitely crush the holes.
waw
Can I get model?
How can we add stock setup in tool path tree.
Under toolpaths choose Stock model.
Also if you have a maintenance contract you can log on to mastercam's website. The forum is really helpful.
in the (milling) toolpaths section stock model
How you move 3d model so smooth?
3d mouse
3d connexion space mouse
Crazy these people and programs are so advanced and yet the GUI looks like windows 95. Artists are not hired enough in corporate applications/software development.
More RPM
어 마스터캠 사용하네
Booom
get a lot of wasted motion with master cam and even catia 5 catia 4 is slower to program yes but much better to draw it yourself!
아니 왜 두산 기계야
anyone working there who don't have a fancy title? ;)
why don't you teach us - and not tell us what you did
Ew stock models... haha i hate them. Get a dirty toolpath regen. Change a depth of a drill regen. Sneeze regen.
hahah thats true
Ya I have noticed that too
Buy an i9-9900K, Quadro P6000, regen
All that work is a complete waste of time....if a finished part flatness tolerance is required.
All work has value ...this project was really cool to make and I am excited for the second operation .
Болтал болтал, а деталь так и не доделал
