Forgot to post for last Friday, so catching up on it today.
The part I'm working on requires an excellent finish for a reflection dome as apart of a flashlight. I used a spiral toolpath with a 1/8" ball endmill and two thou stepover to finish the surface, took an hour per part (approx an inch square), and came out quite lovely! One of the features of the piece I was a little nervous about was where the dome shape met the opposite face of the part at a sharp angle. I wasn't sure what exactly would happen when it cut past that area and was afraid it would either push the material out of the way or leave an imperfect finish. For this reason, I started from the center and moved my way out. Cutting it like this would push the material inward and force it to be cut rather than just moved.
I was also able to cut that small pocket I mentioned in my previous post by using a paralel toolpath with small stepovers, it wasn't the best finish (see picture above) but worked for it's purpose.
Another aspect of this part that I found interesting was the material removal, in the center of the part there is a large hole which would take forever to bore out with a 1/2" endmill (anything bigger would create too much heat). My boss recommended just drilling the center, and only part way from the first op, then flip it over and face the top down to its final height.
