Threaded View

I am a cnc novice trying to learn how to 3d carve using a 3 axis cnc router. The CAD output is an stl file. When I zoom in with an stl viewer, the flat faces that make up the complex 3d shapes are visible.
It may be that the machining resolution will naturally smooth the curves but I would like to know how to do it digitally in case the flat faces are still visible after machining.
Is there a simple function somewhere in my work flow from CAD to CAM to machine that I can perform a 'smooth' function that will either subdivide the stl faces so that they become irrelevant or create smooth curves out of straight lines.
For CAD I am using Blender
For CAM I am using deskproto
My router is an exel 6090 controlled by dsp pendant
I am a complete cnc novice so any explanation will need to be very simple.
Any advice much appreciated. Thanks.
