Manufacturing Projects & Skills
Performed some of the manufacturing processes that are integral to product development, such as lathe turning, welding, and casting.
Look below for more details.
Lathe Turning
Manufactured a screwdriver in 10 manual lathe operations and 2 preset CNC mill operations. The manual lathe operations included 2 facing, 1 straight turning, 2 drilling, and 5 chamfer operations. Once fully assembled, the screwdriver bit could be swapped by means of a magnetic mechanism.
Sand Molding & Casting
This mini project was started in AutoCAD, where I created a 3D model of a medallion by projecting an Aphex Twin graphic onto the front face. The 3D model was then converted to G-Code on MasterCam, which allowed for it to be printed out of wax. This wax figure was placed in treated “Nevada sand” that bonds together when exposed to carbon dioxide gas. The wax model was removed and the bonded sand mold was placed in the microwave for proper hardening. At this stage, the sand mold was prepared and ready to receive the molten aluminum.
TIG Welding
Learned the basics of TIG welding. I definitely wasn’t great at this, but I was happy with this specific weld at the time because it looked “clean”. This type of welding uses a tungsten electrode to create a weld pool that you could add filler rod material to. It uses argon gas to prevent contamination, so I had to hold it at an angle and have it facing its direction of travel.
