There is a lot to learn when it comes to speeds (spindle RPM) and feeds (cutting feedrate). To simplify things and give you a good place to start, we have created a really basic speeds and feeds chart for the Pocket NC V2. See the chart below* or download it from the bottom of the page and then continue reading to learn how to calculate your speeds and feeds. Note this chart was created with 1/8” single flute tooling in mind.

Speed
To calculate your starting speeds and feeds, begin by finding the speed (RPM) recommended for the material you plan to cut. For this example we will use Aluminum, so the RPM we will be working with is 8,500.
