A truly horrendously bad screen capture of the early alpha version of a G-Code Editor I am writing. Sign up for G-Wizard and you'll get the details on the editor when it's ready for Beta Test!

Making a DRO reader bracket for the mill's X-axis. This is a 3/16" 3 fl endmill, 1600 rpm, 5.4 IPM feedrate, and a 0.070" depth of cut. Little bit of chatter where it changes direction and bites into the largest amount of cutter engagement. 5/11/09.

Same DRO bracket. I'm using the Surfacing function from the Newfangled Solutions Mach3 Wizard to cut a little pocket to hold the DRO's read head. That's a 5/8" Iscar Helimill using APKT inserts. 1600 rpm, 20 IPM, and 0.070" depth of cut. The Helimill does a real nice job, and there's plenty of HP and rigidity in the IH mill to take good advantage of it. I'd like to try a 3/4 or even a 1" and see how it did. 5/11/09.

IH CNC Mill surfacing 6061 w/ 5/8" Helimill indexable endmill. 1600 rpm spindle, 10 IPM, 0.100" DOC. Gave a great surface finish!

Shots from my R8 holder rack project. We're cutting polyboard. Most of the racket is my old Sears upright air compressor.  

Flying along at 50IPM to rough the Swing Blocks for a Tapping Arm. Despite the steam from mist vaporizing, the heat was all in the chips. The cutter was stone cool to the touch immediately afterward. Thank you G-Wizard!

The finish pass at 20 IPM (much slower than the 50 IPM roughing to get a nicer surface finish). I used a brand new sharp HSS 4 flute...
