We finished our bean inspection table that we mentioned a little while ago. We’re really happy with how it came out. To make the table, we first talked about the design before sketching some ideas out on paper. Once we had a general design we were happy with, we started the real production process.
The first step in that process is modeling the pieces in AutoCAD. It took a few iterations to get something we were happy with. Once we had everything modeled, we used MasterCAM to create the toolpaths for the CNC desktop router we’d be using to cut out the pieces. Getting the toolpaths exactly how we wanted them also took a bit of time, but we ended up with a nice, efficient cut. After getting everything set up in the digital world, we went to the Tech Shop to bring the parts to life. We started with an air cut to make sure our toolpath wouldn’t hit anything (work holding, bottom of table, etc) and then we cut the pieces out of foam. The foam pieces looked good, so we started cutting the pieces out of HDPE. We had to adjust the feed rates slightly, but, after a little less than an hour, the parts were all done. After that, we assembled the parts, added the mesh, and sealed the joints using a food grade silicone sealant and the table was done!

It’s important to inspect the beans before throwing them in the roaster as there can be lots of junk tagging along in the bag. We decided to build a bean inspection table (a glorified bin with some mesh to let the small junk fall through) to make that step better. We’ve taken some classes at the Tech Shop in the past and this seemed like the perfect time to apply those skills. We modeled the parts using AutoCAD and created the toolpaths using MasterCAM. The video shows the desktop router cutting the pieces out of HDPE. Now we just need to assemble those pieces, add the mesh, and seal everything and we’ll have a fully FDA compliant inspection table.
