I am trying to carve tiny details in small pieces of hardwood (playing around with bloodwood as well good ol’ Maple).
I am using G-wizard, but my bits break every single time. I’m trying to adjust the speeds and feeds, but I don’t know what I’m doing and it’s not working. Also, it takes about 6 hours to do an incredibly small section of the design. To carve my entire design would take five days (at least), and it’s only 1.5" by 1.5." Obviously, I am doing something wrong.
Below are my settings. Some of you are going to wince at these numbers, probably - others will get a good laugh! But once you get off the floor, have pity on this newbie and please tell me what I need to change, read up on, or whatever. I’m here to learn…
Bit: 0.051" micro carbide 2-flute end mill
Depth per pass: .001"
Max depth: 0.035"
Offset direction: Pocket
Also, I notice the spindle gets pretty warm (almost hot), which I’ve been reading can mean it’s rubbing - too slow. So I’m guessing I need to increase the feedrate, but I don’t know by how much. And I’m frustrated that G-wizard’s settings don’t work. I mean, I bought it for this exact reason. I wasn’t; expecting magic, but the amount of time it takes if I follow their recommendations seems extremely excessive, and even at those slow speeds, the bit breaks within minutes.
Any help is appreciated. . .
