Was running at appx 20,000 RPM, with feed rate of 30mm/sec. First did some carving with 60 degrees V-Bit, then did a cutout with 5mm end mill.

Today, I've tried cutting oak for the first time. However, after I slowed down the feed rate and increased the RPMs, finish on carving and cutout was way worse.Ĭan you say, from looking at the picture, what was the cause of those 'hairs' on edges? Feed too slow/fast, RPMs too slow/fast, or maybe I shouldn't try cutting soft wood at all? I was pretty sure the reason for this was that either spindle speed was too low, or feed rate was too high (was running at 40mm/sec feed and 22,000 RPM), and sounds while cutting with end mill were very 'screamy' (scared the hell out of me, to be honest). I've double-checked if it was tightened properly (I even have a witness, hehe). It was 'hanging' out, pulled out for 2-3cm and nut itself managed to mildly unscrew itself - so end mill managed to get out. Reason for that is simple - day before, I've been cutting same guitars out of big piece of wood, and I ended up with end mill literally being pushed out from the collet. Trouble is that I've cut it at 20mm/sec feed, while running spindle at appx 25,000 RPM. You can see it turned out 'hairy' (to say so ). Picture 1 shows attemps to carve + cutout the small guitar (height: 25cm) out of that 'juniper' wood. Seems like that wood is soft, and is a pain to cut. Ok, it's not that bad, but I wonder if you could spare few more minutes of your time (now that you're reading the topic anyway, hehe) and just try to educate me a bit more.īasically, I have managed to first buy few pieces of wood, which turned out to be 'red fir' or 'juniper' (translated using dictionary). After surviving tests with MDF (I didn't break anything and bit didn't end up in my forehead ), I have now decided to try to learn how to cut wood.
