We specially designed a new lab experiment for Mechanical Engineering students who are required to take heat transfer courses as part of their major. The Heat Sink Experiment gives students a chance to gain practical experience with theories about heat transfer. This lesson teaches about extended surfaces and 1D steady-state conduction in finned surfaces by having students analyze, design, fabricate on a CNC mill, and test their own heat sinks. Students get a pragmatic, hands-on way to engage with engineering concepts, gain first-hand experience, and also get introduced to manufacturing processes, all of which provide an edge in the job market.
Fusion 360 is one of our favorite CAD/CAM apps, and it works great with the Othermill. Whether you’re learning CAD for the first time or you’re an experienced CAM operator, these resources will get you milling in no time.
This guide shows you the basics of converting an STL file to a STEP file. STL files are a 3D mesh format mostly used by 3D printers, but in the world of engineering CAD and CAM, most software requires solid models. The most universal solid model format is STEP (.stp, .step). Ideally you'd begin with a solid model and avoid STLs entirely, but maybe you found the perfect object on Thingiverse or you used a 3D scanner, and there’s no reasonable way to begin with a solid model. Or maybe you're already doing solid modeling, but you need to incorporate an STL model into it. This guide shows you a file conversion process that has worked well for me.
Ahoy, fellow millers! I’m Marc Fong, a recent graduate from the Industrial Design program at the California College of the Arts (CCA). This summer, I’ve had the great fortune of designing projects for the Othermill as one of the Design Studio Fellows for Other Machine Co.
Greetings from Other Machine Co.’s Design Studio! My name is Eric Chu and I’m an industrial design student at California College of the Arts spending the summer at OMC headquarters testing the limits of the Othermill.
We’ve used Autodesk’s CAD/CAM application Fusion 360 extensively, and it’s one of the best ways to design for the Othermill. It has powerful solid/freeform modeling modes, rich file support, and integrated three-axis CAM functionality. It also works great on Mac OS and enables easy collaboration between project contributors. If you’re new to CAD and CAM, Fusion 360 is a great first step — and if you’re an experienced CAD/CAM user, it has many of the powerful features you’re used to.
Last week was Autodesk University, Autodesk’s annual software conference for 9,000 engineers, designers, architects, and artists. It’s an amazing event, focused on making of all kinds, but this year there was something new: a student hack!
Today, in a matter of hours, I went from never having done 3D CAD to having a physical object from an idea I had. I went through some tutorials and got a bit of nudging from the people on my team, but the only barriers standing between me and this wood cut were what I knew, not the quality of the tools involved.
