WHat spindles speed / material thicknees / cutter diameter.
Machine ridgidity will have a marked effect of the surface appearance as well. You can see what you cant feel.
2 flute straight cutters 3/8 or 1/2" I have had excelent results at 15-20 k spindle speeds, air blast and 100-200 ipm feeds. So acrylics are harder or softer which will also affect the cut IE cast / extruded sheet.
To get a perfect edge a diamond cutter will works best, and a diamond edger will give you the best machined finish.
Hope that helps. |
