Even if you’ve only done just a few projects on the Othermill or Othermill Pro, you know the importance of using the correct feeds and speeds for your design and material type. This is a topic we’ve previously covered in detail in our Speeds and Feeds Guide and Materials Guides, but with the recent addition of SVG milling in Otherplan, we've made it possible to mill designs without creating G-code or thinking about speeds and feeds ahead of time.
Using SVG files is an easy way to mill simple shapes without using traditional CAD and CAM software. When you use SVG files, you can create your design using clipart, screenshots of images, hand drawings, or your graphic design software of choice, such as Illustrator or Inkscape.
New media designer and ITP master’s student Dhruv Damle recently wrote in to share a beautiful project he made using one of the Othermills at ITP’s Soft Lab: his oak and aluminum abstract map of Manhattan.
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.
Teaching engineering is hard. It’s one thing to explain concepts, but most students require concrete, practical examples in order to fully understand those concepts. Practical examples cost money, and they also require time and effort to develop. That’s why we’ve started creating free educational content for Mechanical Engineering courses!
In many Engineering Mechanics and Materials classes, “dog bone” tensile test specimens are required at some point, as part of determining the yield strength and ultimate tensile strength of various materials. For each of these materials, the test specimens are often milled one at a time in the university’s machine shop by a certified lab technician, until there are enough for the entire class. What if there were an easier way that didn’t require a machine shop or certifications, and could even be used as a teaching tool?
It’s hard to manufacture stuff repeatably. Unlike the software universe, where you can make exact copies, the physical universe isn’t uniform and nothing is created exactly the same way twice. Everything manufactured from physical materials falls on a spectrum, and it’s up to you to decide what part of the spectrum you’re willing to accept.
Greetings, metal heads! Diana here to share the best metal projects roundup for this Metal Monday.
As director of sales for Other Machine Co., a question I get asked a lot is, “Can the Othermill mill metal?” To which I reply, “Why, yes it can!” This tends to be followed by a sideways look and a skeptical “Reaaaaalllly?” So I’m here to dispel any rumors or myths about our tiny machine CNCing aluminum, brass, and other metals.
