I’m using a Carvey, and the Aspire 3D software. Although what I’m attempting to make has nothing to do with actual 3D modeling, or anything like that.
Using a .25 inch end mill, (shank & diameter) (2 flute, up cut) how long do you think it should take to cut two round blocks, each 2 inches in diameter from a piece of soft maple that is 3/4 inches thick?
I ask because I’ve been trying to make this box for over a week and a half, and so far everything goes fine until it gets to the profile cut to cut the actual bottom and top pieces out. I have tried a vast multitude of settings, but each an every time, it gets hung up, and deflects, and is just all over the place after that. My last attempt the settings were set to
Pass Depth 0.03
Spindle Speed 12000
Feed Rate 30 in/min
Plunge Rate 9 in/min
Est Cut Time 2:06:22:
It made it about 3/4 of the way through when it just hung, veered drastically off course, and caused an error to pop up in Easel about the spindle being over worked…
I am apparently either doing something obvious yet significantly wrong, or I am cursed at working with CNC and/or wood.
As I have said, I have tried a multitude of settings… faster, slower, higher, lower, deeper, shallower… Some get further than others, but eventually, they all just hang or deflect significantly off course.
Supposedly the Carvey can cut a piece of wood 2 inches thick, and sometime even 3 inches depending on the cut. But I can’;t even get through half inch soft maple.
My pocket carves, and the profile carves for the lips all work great. Just cutting them out of the block is giving me fits.
What should I be looking at? I’ve been trying this for so long, I’m at the point of just trying random settings. I’ve gone through so much wood trying to get this thing made, it’s costing me a small fortune. I suppose I could set my pass depth even shallower, but at 0.03, it’s already a two hour cut for something that should be a whole lot quicker.
I can attach the aspire file if it would make any difference, but from what I can gather by reading the interwebs, this should be a fairly straight forward cut. I can go to a smaller bit, but to make such a small box shouldn’t take hours to cut on a CNC, should it? What’s the average length of cut time for a .25 end mill, .75 inches of wood?
