Design for Manufacturing: Can We Mill This Master Cylinder Adapter?

Posted by Sam Prest on Feb 21, 2017 9:18:40 AM

The part in question, with tooling, rendered in Fusion 360.

People often contact us asking if a specific part they've designed can be made with a desktop CNC. In this article, we use one example part to show you how to determine if a part can be milled and what size tools and raw material we’d need.

New Accessory Turns Your Othermill into a Production Tool

Posted by Owen Smithyman on Feb 23, 2016 7:28:05 AM

We’re excited to announce our new Precision Fixturing and Toe Clamp Set, a collection of accessories that allow for unsurpassed finish quality and precision. Much like a vise, the clamps are quick to apply and remove, and the increased rigidity versus tape or glue yields a better surface finish and extends the life of your tools. The Precision Fixturing and Toe Clamp Set enables you to:

Building a Campus Makerspace? Here’s How to Plan for Safety When Adding CNC Machines

Posted by Danielle Applestone on Feb 22, 2016 3:47:12 PM

Whether you’re creating a campus makerspace from scratch or wanting to add CNC (computer-numerically controlled) machines to your space’s tool offerings, there are a number of logistical and safety concerns to bear in mind. Depending on the type of machines you’re considering and the rules and regulations of your campus, different categories of safety concerns may come into play.

The Heat Sink Experiment, a Heat Transfer Teaching Resource from OMC

Posted by Owen Smithyman on Feb 8, 2016 12:13:37 PM

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.

Introducing the Bit Fan, a New Othermill Accessory You Can Make

Posted by Owen Smithyman on Jan 27, 2016 8:42:15 PM

We just developed a really cool new accessory for the Othermill that makes your tools last longer and gives your milled parts a nicer surface finish. It also enables you to to see your workpiece more clearly. Win win! We call our new friend the Bit Fan. And the best part is that you can mill your own Bit Fan in 7 minutes!

Update: based on a suggestion from user Peter Luong, we made an STL version of the Bit Fan. If you don't have HDPE but you do have a 3D printer, you can print the Bit Fan!

How to Make PCBs On a Desktop CNC Mill

Posted by Owen Smithyman on Jan 22, 2016 10:30:00 AM

This post provides an overview of how to design and prototype printed circuit boards on a desktop CNC mill. Most students do not have access to a CNC mill in their electrical engineering or electronics classes. In most classes, students make circuits using breadboards, which allows them to make connections by plugging wires and components into a grid. This method is great for very simple circuits, but it quickly becomes messy as circuits increase in complexity, to the point where it becomes very difficult to troubleshoot.

Milling Tensile Test Specimens in the Classroom

Posted by Owen Smithyman on Jan 5, 2016 12:01:06 PM

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?

Education Is in Our DNA

Posted by Goli Mohammadi on Apr 29, 2015 10:30:00 PM

It’s impossible to tell the Other Machine Co. story without talking about our roots in education. The predecessor to today’s Othermill was developed as a part of a research and development program to “reinvent shop class for the 21st century.” And though the machine itself has changed and become fine-tuned over the years, our commitment to our original mission has stayed the same.
