There's a video on YouTube about a medical company making spinal implants outta titanium on dt1s. I'm just cutting plastic... I just wonder how solid they are as far as longevity running the spindle wide open all the time. I read on cnczone or practical machinist that they were having spindle issues back in 2011ish. I would think that's been corrected by now right?
-
Our parts that were running now have +/-.002" position and form.

Anyone ran these for long? I see the TRT-100(small budget 5th axis rotary) out now and was wondering if I could make this machine and rotary combo work for what I need... I'm just cutting plastic but I'd like to hold +/-.001 if I need to. Also wondering about reliability down the road.

Cat40 Thread Whirling?
JMahon replied to Matthew Hajicek - Singularity's topic in Machining, Tools, Cutting & Probing
How would you go about programming that on a 5 axis vertical? -
Hit the toolpath button in ops manager. The lil squiggly line that turns toolpath lines on and off

I forgot to check that file, super busy day. Can you post a file? Maybe it would do better with a full stepover, light depth cuts, with say a 3/8" end mill with a .060" radius...?
-
How big is the part? Have you considered going with a smaller tool. I milled several parts with a 1/4" Garr v5 around 300sfm with no trouble. I'll check my file tomorrow and post the cut parameters. Maybe I just got lucky!
-
With a .03" corner radius. .500" depth of cut, fs wizard is showing around 300sfm and .0023 chip load. I've cut cobalt chrome at these speeds/feeds. But it was with a 1/4 end mill and it was only a few parts. Sounded good though
-
What depth of cut? How many flutes? Corner radius?
-
What version are you running
-
Try the feed speed wizard. Or post your cut parameters and I'll plug it in for u. In my minimal cobalt chrome experience, I actually found that most folks are feeding too slow.

Turret Recovery operation on a ROBODRILL
JMahon replied to Mike@Lustre's topic in Machining, Tools, Cutting & Probing
Go to quick nc button. Go to maintenance/setting, then do turret restore(1). Then follow the directions on the screen -
Use the stock model "toolpath" If u can load a file I can try to help
-
So did you get it to work?
-
Surface rough it, then finish it by hand coding the finish pass. Shouldn't be that hard on a cone
-
So u want the same thing, just have the part pointing towards the spindle?
-
Here you go... Hope this is what you were looking for. FLOW.mcx-9

You have my attention! Care to elaborate on this?

That's definitely doable on the mastercam side. How you go about it will depend on your machine and if you have 5 axis in mastercam.
