Chapter 12 I Examples

Next I used the Dremel to carve the dolphin in pink insulating
foa m, the kind you can get at the local building supply store. I
ope ned the do lphin image in Profll cro, after 1 had colored it w ith
shades of gray in CorelDraw and expo rted it as a jpeg image fi le.
Next, I generated a G-code fil e th at wo uld carve the dolphin. Using
an image of the dolphin with a white background so that only the
dolp hin wo uld be carved, I made the carving seen in Figure 12. 15.
I used a l iS-inch cutting bit and only over lapped the cuts the min-
im um that can be set w ith Profile r6.

The dolphin is only 2 inches at its w idest point and 5 inches in
length. You w ill notice that th e carving is 1/4 inch at the deepest
cut, and that the figure is highest at the head, giving the ill usion of
emerging from the foam. I changed the image of the dolphin, mak-
ing its body similar shades of gray and the background black.
Again I opened th e file with Profiler6 and gene rate d G-code to
open w ith KCam. This time I used pine to carve the dolphin. The
result of the changes can be seen in Fig ure 12.16.
