Hello, I am a beginner with milling so any help is welcomed. I need to make some round moulds in a steel stock.

I need to form a .6860 +/- .0001 Dia. counterbore by .300 deep. The through hole is .500 Dia. The bottom of the counterbore is not flat, it's angled at 15 degrees. Material is Aluminum casting. Machines available are CNC lathe or CNC mill. I can get a step drill made up that will put in the .500 Dia. hole, 15 degree floor and rough the .686 Dia. Get rid of the flat bottom end mill and use one of these: Harvey Tool - Carbide Drill/End Mills - Drill Style 2 Flute . Rochester, NY, USA.

I ended up laser cutting a template that would square up the left side, and locate the front left corner. The template also has a hole to sweep for the XY origin. Have to run the part in 4 ops. 1) stick a one inch bar stock on a vise end up. Use a 1/4 inch end mill (size doesn't matter) and eyeball a center on the top of the stock. Make this your work offset.

While tapping in Delrin (thankfully, it was this material), I encountered an issue. As the tap reached the bottom of the hole and reversed, I noticed that the Z-Axis didn't stay in sync with the spindle's acceleration, resulting in the tap pulling my part out of the vice.The next concern is the quality of the part. The bigger the gantry the more possibility for flex and vibration. On the mill the machine’s most rigid sections move with the spindle and that rigidity is constant. On the router you have a .
