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
