certain controls only read so many lines of codes into a buffer,ie it waits to flush and refill,some controls ie siemins have look a head codes,it could also be down to spin up times ,ie changing speeds..can also be affected by age of machine ie 32 bit faster than 8 bit.
Good video Barry. Did mastercam tell you that you'd rub on the tabbing op? Or am I seeing something else? Also, is the machine control the reason for the choppy 5 axis deburr, or the code?
Maybe he didn't get the "High Speed Machining" option when he bought the mill? HAAS sux about that. I want to turn on Ethernet but it's $1999 just to activate the network function.
@@barrysetzer did u run the machine as well ? Maybe the end mill was resharpened End mill flutes are already smaller then the tail depending on manufacturer ( on what I use between 0.03 and 0.05 mm smaller ) if it's roughing I don't care much about rubbing , for finishing I always grind the end 0.2 mm or so smaller , just to get the length I need , not even 100 mm is long enough laitly
This is how all 5 axis work goes for me. The more the machine does the better. For the tool axis control it's better in my experience to use 3+2 motion as apposed to full 5 axis. Full 5 can cause jerky motion if your filtering isn't tuned for the machine. 3+2 will tilt and park for each cut creating much smoother, and as a result, faster motion for the cut.
Absolutely! I was really impressed at how well Mastercam plotted out the 5 axis motion however, while avoiding the tapered shank of the lollipop etc. You can easily lock that toolpath into 3+2 or 3 axis, though, if you're wanting super smooth fast action.
We have small die grinders at our shop. We've got sanding discs for removing the large portion of the tab and we switch over to a scotch brite disc to polish the surface after that. Once you get good at it you can easily produce a flat surface that doesn't vary by more than a thou, and easily match a tab up to a rounded surface too. Just takes practice is all. Like they said: once you finish the part completely in the machine all you have to do is clean up the tab after breakout, and that goes pretty quick.
@@virtuosisimo It was a 50mm dia.U-drill but it was my fault being a new machine and acting cautious and being the first part I always check Z height to make sure there is no programming error by using feed hold knob but that time accidently turn down rpm knob and as you know not enough speed for feed and up chipping the insert before I could react to it.Actually noticed couple of weeks ago there is another chipped glass on the other side caused by flying chips,luckily it hasn't shattered like otherside.
im sure, it will run way faster if you debure, the edges in a 3 axes chamfering toolpath and just rotate the part from angle to angle, the 5 axes simultanius toolpath runs slower. its not necessary at this part. its a little more programming work, but its saves cycletime.
Sometimes when you have a bunch of small moves in a row the control can't keep up with speed of the machine. It's commonly referred to as data starvation. I'd be willing to bet the code for that deburring is massive.
@@brandons9138 Data starvation may have been an issue on older machines, but on modern controllers jerkiness can be due to the toolpath being poor, the smoothing settings on the control, the machine dynamics, or more frequently it a combination of all 3. Id bet that with a change of some toolpath settings and setting the AICC correctly you'd get nice smooth motion. The reason its jerky is the controller is trying not to violate the toolpath given the tolerance settings in the AICC.
@@sr20starlet You know, I didn't consider the age of the machine. This is a brand spanking new machine, so I'm sure the control is more than capable of keeping up. I haven't done much five axis simultaneous work. It's not the type of work that comes across my desk very often. If ever.
Personally, I don't like to use just the tip of a large tool to prevent inequal wear. Of course, if you're just going for speed and mass production, few seconds cost on tool change tend to pile up.
We could have easily done that in the CAM software, but in this toolpath we were maintaining a constant stepover and angle of engagement. In the end, there wouldnt be any noticeable time savings in slotting, as the feedrate would need to be slower.
More videos with this dude
That tab reminds me of the sprue in injection molding. (A similar concept.) Nice video, guys.
Huh neat. That makes fixturing a lot easier.
good video titans..thanks for your time
Nice Video! Before the Multi Axis Deburr toolpath came to Mastercam we deburr our 3D edges with Morph or Parallel.
Yeah, the new deburr toolpath is SO much easier, I love it!!!
I convinced my Supervisor to buy the Kor 5 for aluminum. Today I tested it for the first time. Very nice, very fast!

Greetings from Buenos Aires. ..Argentina. ...
Finally a programmer who enjoys his work
At 6:02 it looks like the shaft of the endmill is rubbing against the part, because of the sparks at the top of the endmill or am I wrong?
Yeah, not too sure how that happened, at 5:42 you can see we cut all the way down that contour with the same tool.

Sore that too, not enough information. Can’t overlook the small details.
It's funny, at 5:48 you can see that I cut down that entire contour with the same tool.......it must've been a chip that rolled over.

Cutter is rubbing on the shank when parting off. Pretty sure you heard it do that, right….? 🤭

why is the roughing SFM so wildly high? is it because it doesn’t matter so much with 1018 steel?
I see sparks and my old conventional machinist ass freaks out and goes into Danger Will Robinson Danger mode!!! And then I saw ceramic, holy meltdown!
Can you go over tabbing in more depth in a future video? How to eliminate and blend the tan after you break it off? Please an thank you.
Absolutely. Also read comment below where I just explained benefits

thank you for the video
4 minutes and 33 seconds of video
the softness of the machine.
no stickiness
Is the cam the problem?
Is it a machine problem?
Problem fanuk
Heidenhain no problem
How long time had you for the programm
It took about 3 hours to program and had a cycle time of around 22 minutes.
Wat happen to the Machine window?
Nice
Barry, do you use any kind of machine simulation software?
We use the simulation in Mastercam. But as far as Vericut or NCSimul, no.
Love the vids guys, but i wanna know the story behind that smashed window in the doosan :P
Anyone ever: "it was like that when I got here"
Lol
Looks like it must be common.Mine got shattered by a chipped insert, only 2 months old it was and cost me $630 AUD very disappointed.
@@mehmettemel8725 that's enough to shatter a window 😳

Imagine the guy who had to come up with the program to figure out that tool path automatically.
I think about that alot!
cool
Yeah why’s it sticking like that when chamfering? I’d think it would be a smooth contour cut and not so choppy.

Is that part NOT dovetailed? And you're taking that big of a cut at the beginning? What vise is that?
No, it isn't dovetailed. The jaws are serrated, and its a Schunk Kontec KSC125.
@@barrysetzer Thank you! We currently use a vise from 5th axis and it doesn't have this holding power.

Not showing pulling the part off the tab is like my wife changing the channel right as Joe Montana drops back for a pass…..
Why not at the 0:50 mark. Edit the code manually to take off that whole fin at once? Instead of going around multiple times.
We could have easily done that in the CAM software, but in this toolpath we were maintaining a constant stepover and angle of engagement. In the end, there wouldnt be any noticeable time savings in slotting, as the feedrate would need to be slower.
