Here are the final photos, point placement, and definition of the point field study. The point study was conducted using a grid of points that were manipulated in the Z direction by the placement of one defining point. As a result, a rippling effect took place with the points closest to the defining point being near or at the surface and points that are farther away from the defining point getting progressively deeper in the material.
The material study took place using the 1/2 ballend tool rather than the standard 1/4 drilling tool. Using this tool resulted in a varying diameter that was determined by the overall depth of the point. Keeping the layering of the material in mind, the points were intended to step down until reaching 0 at which point the tip of the bit would slightly penetrate the last layer of material allowing light to pass through at the fields lowest points. Unfortunately my measurements were slightly off and the bit never passed entirely through the material. However, light penetration is still achieved at the translucent portions of the material where only a single layer of plywood remains (see images).
Some fraying occurred despite adjustments to the mill speed but other than that the material handled the cnc plunging operations well and resulted in a good depth of field by exploiting the layers of the material.
