Formula To Determine Feed Rate. This formula can be used to figure out the feed rate that the cutter travels into or around the work. This would apply to cutters on a milling machine, drill press and a number of other machine tools. This is not to be used on the lathe for turning operations, as the feed rate on a lathe is given as feed per

Machining Fundamentals: Intro to Speeds and Feeds

08.12.2021The phrase speeds and feeds refers to two separate velocities in machine tool practice, cutting speed and feed rate. They are often considered a pair because of their combined effect on the cutting process. Each, however, can also be considered and analyzed in its own right. To start, we'll define speeds and feeds.
