For this assignment, we used Easel to create a design that we wanted to CNC using the CNC machine in the machine shop (Figure 1). Afterwards, we were supposed to post-process the block of wood in whatever way we wanted.
Initially, I used the CNC machine to cut
out the block shown in Figures 2 and 3. The cut actually turned out quite well. However, I tried post-processing it by taping the uncut wood and spray painting the rabbit and duck. Unfortunately both spray paints were very watery and did not cover the wood in a thin film. Rather, the liquidy spray paint pooled up in the cut wood (Figure 5).
The final product after I took off the tape and also stained the wood did not look as good as I’d hoped, so I decided to redo it with a slightly different engraving (Figure 6).
The next time, I used the design shown in Figure 1. However, I forgot to change the bit, so instead of having the flat bit, it used the round bit. I decided that it wasn’t worth redoing the whole thing, and so I post-processed the new wood block (Figure 7). I decided to use red paint this time. However, it was quite troublesome because it’s difficult to paint the inside engraving. I also stained the wood on top, but it would seep into the engravings, and the wood stain was also very gooey and sticky, so the resulting texture wasn’t that great (Figure 8). Honestly, I actually really like how the non-post-processed wood blocks look much more than when they’re processed. If I could do this process again, I would rather have kept them unprocessed. However, I did learn a lot about using spray paint and paint and stains and how things never go as you’d expect. All in all, I think the CNC machine was pretty cool to use, and I like how the wood pieces look after CNCing them.
