Video Session - CNC Crashes

Every CNC machine operator crashes his tools to some degree. Period. It's a trial and error process until you truly become competent in your own toolpath engineering. Here is a compilation of quick videos that express every toolpath engineers worst nightmares. Some of these I have done myself, so it's a fun reminder to learn from your's and other's mistakes!

Be sure to skip ahead in the video to the time posted.

P.S. You can find more fun CNC videos on my Facebook and twitter page

Fun art on the 4 axis

Successfully took a multi-faceted obelisk from design to a finished part using live tool plane 4-axis machining. One part took about 3 hrs to complete. Roughing was done using only the top and bottom tool planes, 3 operations per side using a 0.5" end mill.

The finish pass was done using an "axial cut" live 4 axis toolpath, which is when the rotary table moves 1.5 degrees after the cutting tool has traveled the entire length of the part. See video for example. a 1/8" ball nose cutter was used with mineral spirit being added for a smoother cut finish.

 5 operations were needed to separate the ball end of the part from the raw material

I'm not really sure what it does, but it looks cool!

I also completed a small sheetmetal project. This is a custom funnel for a 55 gallon drum.
