The mill will treat the XY plane as the top of the material, anything above the XY plane will not be cut. The surface should be placed with the highest point on the surface is just below the XY plane.

The optimal surface for machining is NURBS based, this can be created in Maya, Rhino or 3DMax. As you prepare your surface the modeling environment should be set so the Z-axis is vertical and the working units are inches/feet.

This tutorial covers the basic opera-tions needed to do a Rough tool path based on a generic 3D surface.ฤก) The creation of an appropriate surface for machining is the first step in the Surfacing operation.

If a smoother finished surface is desirable a second series of cuts can be made with a smaller bit at a tighter interval giving a smooth polished surface. Often the process is stopped after the Rough process, and if the roughing operation is done with a small enough bit the surface smoothness may be suitable for many applications. The purpose of the Rough pass is to remove as much material in as quick of time as possible, this is typically done with a large bit and gives a rough couduroy texture to the material. Typically this is done in two operations, a Rough pass and a Finish pass. Surfacing is a machining operation in which a 3D contoured surface is carved from a block of stock material through a series of cuts.
