WEEK 05

CNC MILLING


I WAS REALLY LOOKING FORWARD TO THIS WEEK, I HADD PLANNED OUT MY DRAWING THE WEEK BEFORE, HAD MY MODEL DONE BEFORE CLASS SO I COULD GET IN ONE OF THE FIRST TIME SLOTS TO CUT AND AVOID TRAFFIC. I GOT A NICE PLYWOOD BUT I DECIDED TO CUT ON THE OSB FIRST, TO TEST OUT THE DESIGN AND SINCE I HAVE IT ANYWAY. IT WAS A GOOD IDEA BECAUSE I DIDNT LIKE HOW MY DESIGN TURNED OUT, BUT I ALSO DIDNT GET ANOTHER CHANCE TO CUT BECAUSE I WASNT ABLE TO GET ANOTHER MACHINE TIME.
FIRST THING I DID WAS MAKE THE MODEL AND SLICE IT UP IN FUSION SLICER, COMPILED ALL PIECES ON ONE 4 BY 8 SHEET. SETTING UP THE FILE ON VCARVEPRO TOOK FOREVER BECAUSE OF HOW COMPLICATED MY FILE WAS. TOM HAD SUGGESTED I USED A 1/8 BIT INSTEAD OF THE 1/4 TO GET INTO ALL THE NOOK AND CRANNYS. SETTING UP THE MACHINE WAS RELATIVELY EASY, JUST HAD TO GET USED TO THE ORDER OF THE STEPS. AFTER CUTTING THE PIECES I LAMINATED THEM IN STACKS, AND SANDED THEM. SARAH HAD SUGGESTED I USED THE MACHINE FOR CONTOURING THE TOP AND IT WOULD HAVE SAVED ALOT OF SANDING TIME, WILL TRY THAT WHEN WE GET TO CASTING MOLDING WEEK.

I WANTED TO MAKE A CHAIR THAT LOOKED LIKE A PAIR OF WOODEN LEGS GREW OUT OF WHATEVER SURFACE IT WAS LEANING ON, SO I USED STEEL AS FRAMEWORK. MY DESIGN WAS MODELED AFTER A FEMUR FOR THE ARMREST AND STUMPS FOR THE LEGS, THE FEMUR HAD A FORAMEN AND CONDYLES, BUT BECAUSE I SCALED IT WIDER THAN I INTENDED (ACCOUNTING FOR THE POOR MECHANICAL INTEGRITY OF THE OSB) IT HAD TURNED OUT MORE PHALLIC THAN BONE LIKE. IN HINDSIGHT I SHOULDVE JUST PROCEEDED WITH USING PLYWOOD ON THE FIRST CUT AND STUCK TO MY DESIGN.
