Ways to Calculate Feed Rates

In this video, you will learn about feed rates. There are values that need to be calculated so you can evaluate the RPM. There needs to be some kind of ratio between diameter and circumference. This is calculated with the pi equation.

The distance of a tire from the road is always 3.14 greater than its circumference. End mills work in the same way as this. A tool can only go a certain speed. In machinist talk, when we are talking about speed, we are talking about cutting speed or spindle speed. Cutting speed is surface meters per minute. Spindle speed is revolution per minute, or RPM. To control a machine, it needs a spindle speed. To get from point A to point B, you need a formula. You can concert meters per minute into a spindle feed. Once you have this value, you can calculate the RPM. This is precautionary so that you don’t have any machines wearing down. Equations can be simple because you only need to figure out one variable, usually. There is a lot to know. If you are interested in learning more, keep watching this video for more information.
