In this episode Ben explains the ins and outs of CNC milling using only a Shapeoko and a laptop. Areas of focus include an overview of the parts, creating design files, execution and other CNC tips.

Free and easy milling software

Small consumer milling machines are becoming more and more popular these days, and it can be a huge benefit to have your own CNC mill at home, not to mention that they are much cheaper than laser cutters. But how do you control the machine? Most consumer CNC mills are 2.5D mills, that is, they are mainly used to cut things out of sheets. If that is the kind of mill you have or are interested in, good news! has a simple program that you can use to turn a black and white image into CNC programming for your mill! You don’t even have to install any program, since it works directly in your web browser. In this video, I Like To Make Stuff gives us a walk through how it works and what to keep in mind when milling out pieces at home. Just watch and enjoy!

The trouble with stainless steel machining

The difference of malleability between metal alloys can be quit big. Some cuts like butter, others are so stubborn they almost seem to have a mind of their own. One of the more difficult alloys to machine is stainless steel, but even here the problem is more or less pronounced depending of what kind of stainless you choose. If you plan to mill any stainless steel material, you should definitely watch this video by NYC CNC where the choice of stainless alloy, speed, feed and many other factors are carefully explained to help you mill corrosive resistant parts in no time. And if you really want to see how bad it can get, forward the video to 11 minutes and 30 seconds, and you will see a horrible little firework!

The benefit of roughing end mills

If you own or have access to a metal milling machine, you should definitely look into buying a roughing end mill. Like NYC CNC testify in this video, roughing end mill can not only reduce the milling time by a huge amount, but also expand the lifespan of your mill bits! It is definitely a worth while investment, and if you don’t believe us, just watch this video!

What is cryogenic manufacturing?

Have you ever wanted o make something out of rubber? Not just a smooth ball, but something complex? Sure, 3D printers can print soft objects today, but they are very limited. Wouldn’t it be great if you could take any rubber material and just mill or lathe it? Well…you can! You might have seen scientific demonstrations of how hard and brittle things can get when deeply frozen? Leave it up to our scientific favorite Applied Science to test it out and see how it might work. You might even be able to make your own specially designed rubber parts with nothing more then an mill and some dry ice!
