Speeds & Feeds & Tools for Cutout Profile in Wood
I primarily cut metal, but I have been messing around with doing some wood projects with my CNC Mill.
My question is, in 3/4 inch wood, mainly pine and oak, what is the best tool, depth of cut, and feed to use?
I've tried several straight style router bits in 1/2" and 1/4" at high RPM (around 25,000 RPM), and also 2 and 4 flute end mills at lower RPM (around 3,000 RPM). The best overall result seems to be the 1/2" two flute (two cutter) straight router bit at 25,000 RPM with about 1/8" to 1/4" DOC and 15IPM feed, but that wastes a lot of material. The 1/4" two flute router bit (same settings) doesn't allow enough room for the chips to blow out and I actually broke one of my bits.
With the end mills, I get a lot of overheating (discoloration on end mill) and burning of the wood even at lower speeds (about 3,000 RPM). Not to mention a horrible banshee-like squealing. The mills are razor sharp, not just using my old metal cutting bits or anything.
SO, long story short, I was just wondering what tool and settings most people use for cutout profiles.
He is more machine now than man.....
