    Improve Surface Finish

    Hey guys,

    I made my first part with the Tormach today (PCNC1100) and I was quite happy. But the surface finish on the sides are not great.
    Here is my settings:

    Material : 6061
    Tool: 1/4in / 2 Flute

    Step #1: Roughing - I do 2D contour with ramp, I leave 0.004in for finishing pass
    Spindle: 5100
    Feed rate: 17 in/min

    Step #2: Finishing Pass- 2D contour with ramp,
    Spindle: 5100
    Feed rate: 21 in/min
