Some Information about End Mills (Rotational Cutters) for CNC Machines
I receive a healthy dose of questions about end mills and which ones that I use. I usually respond with answers like, my end mill will probably differ from your end mill. So, what is this thing called an end mill anyhow? If you are new to CNC machining and routing, you may have never heard of the thing. I could imagine googling something like, "CNC bits". Using the terminology "bit" is not all that incorrect. Bits are commonly referred to as drill bits, but routers use router bits. If you're looking to cut various metals and composites, end mills are the tools of choice. However, end mills will also work on wood, depending on the type of end mill selected.
Torque and Linear Motion Formula
Periodically, I get questions from users of the site regarding torque and how much is required to move certain masses and a recent user emailed me specifically and it gave me the happy motivation to add this page. :) These masses are things like the gantry, or the z-axis assembly with the router mounted moving on the y-axis, or the just the router mount and router within the z-axis assembly. The question is usually in the form of, can my ??? oz-in motors be used on your CNC machine.
