I'm attempting my first mill-turning on my Tormach. This is where the stock is held in the spindle and the lathe tool is in the vise. I'm machining 3/4" diameter brass. I'll hold the brass in a ER32 collet with 1.5" stick-out. The post processor for this doesn't accept constant surface speed or speed per revolution. I have to use RPM and feedrate, just like normal milling. Brass is pretty forgiving, which is nice. I'm looking for some starting RPM, feedrate and depth of cut suggestions.
