cool vid :)
I like this App this can be useful for many CNC setters/operators
Hey there,
i'm glad you released a new video, i really like them. First of all we are running the exact same setup as you do. Mastercam 2021 with Mori Seiki machines, or DMG Mori's as they are called nowadays.
I really like the dynamic facing toolpath, but we use "one way with Rollin" whenever we are able to. The reason for that is that i feel that i have more control over the toolpath compared to the "facing" operation. You are using 5 cuts to face a 105x105mm part with "standard" facing. The problem is that the first and the last cut are some kind of "bad". 4 cuts should be ok because 105mm diveded by 4 is 26,25mm which is below your maximum programmed ae of 30mm.
As a result the cycle times are somewhat equal when you compare "one way facing with rollin" and "dynamic facing". At least this is my experience. Dynamic looses a lot of cycle time on the "entering" cut, as the Mastercam slowly increasing the with of cut to the desired maximum. This problem gets even impact if the cutter and the maximum ae is getting bitte (like 100mm Cutter with a maximum ae of 75mm). It just takes some time to reach that full cutting load.
Another downside of dynamic facing, at least from my experience, is, that it leaves that little burr in the middle of part cause of the corner radius of the cutter and inserts. I dont know if Mastercam has a new option for version 2021, but i think it has been this way since they released the "dynamic facing" toolpath. I remember to always cheat a little bit on the cutter diameter to get rid of it.
Please keep producing those good quality videos where you compare stuff!
Best regards,
Nico
Hi, thanks for your feedback. You are absolutely right. We are not saying which toolpath is the best because it always depends of part, tool, machine etc. Different toolpaths effects on surface quality, cycle time and tool life.
This workpiece was cutted with torch and one way toolpath is not optimal in that case. We did get best surface quality with dynamic toolpath and I'm sure that tool life is the best with it. With right workpiece and right tool you absoutely get best surface with one way toolpath.
When you are programming facing operation with Mastercam you need to add tool corner radius to the tool geometry and so it works right. Personally I make all dynamic facing operations with 2D Dynamic Mill so I can use air regions, avoidance regioins and Rest Material on the Stock page.
@@CamcutFi MV Junior's are Legendary Grade CNC Mills. Do you have any videos of maxing out that cutter?
Thanks for the comparison. I also did a comparison between Face Dynamic and 2D Dynamic and came to the same conclusion. 2D Dynamic just has better options and you may as well use it to begin with. One thing I have noticed is that Dynamic tends to cut a dish or bowl shape with our current tooling. Rigidity is still the king.
Wow, I thought we were the only ones with a mori like that!
