I have a job machining a 1.5” thick piece of 12”x12” cast acrylic. It is a demo piece for a company demonstrating a mobile imaging tool for ultrasound inspection of carbon fiber components.
This is a semi loose tolerance piece with a selection of flat bottom bores of various diameters and depths.
I would like to have a few recommendations on feeds, speeds, tooling etc for circular interpolated bores in cast acrylic ranging from 1/4” to 2” diameter and 1/4” to 1.25” deep. I am looking mainly for as clean and aesthetically,optically clear bore as possible.
I will also be doing a simple logo engraving. I have done simple engraving previously with a center drill or spot drill but will spend money on tooling to make a clean engraving. I generally give a light polish after engraving stainless or aluminum to deburr but I assume this will not be possible as the clear plastic will show all marks from polishing.
I have a VMC with 10k rpm spindle. Please tell me if I missed any important info.
