I had an opportunity to visit the Gene Haas Center for Manufacturing Innovation last week. I loved it! I was like a kid in a candy store. This brand new center has areas for CNC (subtractive manufacturing), manual milling, lathe work and grinding, 3d printing (additive manufacturing), pneumatics, hydraulics, robots, mechatronics and more! I was there for a lunch and learn that featured 3d printing technology from HP and MarkForged and also 3D design software from Solidworks. This facility is used by Greenville Technical college, Clemson University and also by local industry. They are also starting an business incubator very soon. Watch the video below for more information.
LED Can Light – Start to Finish
In this start to finish project we go through the entire process from Ideal to finished part. First we do the 3d design on the computer using Onshape. We then CAM (create the tool paths that tell the CNC machine how to actually cut the part) using BobCAD/CAM. Next we use a 5C collet fixture to hold the stock and test cut the part in plastic. Finally we cut the design from 1 inch (25mm) 6061-T6 aluminum bar stock. The lens is made from 1/8 frosted acrylic. You can tell in the pictures that this process made a big mess! The tolerances on the lens were “spot on”. The KR33 CNC is a beast of a little machine
I polished the aluminum version and that made it pop. It’s a nice, compact unit. I still need to finish them and mount them to the machines. One issue I have is finding good wire to use.
There is a new online CAD software that allows free use. With Onshape you can design parts, assemblies and drawings. The basic account is free and limits the number of projects (currently 10) you can create that remain private (only you can see them). The rest will be public so that anyone with an Onshape account can access and use them. They also offer a professional account for $100/month that allows all your files to remain private.
They’re also working with other OEMs to bring added functionality into the cloud based software like CAM and finite element analysis.
