What does the term "feed rate" refer to in machining?

The term "feed rate" specifically refers to the speed at which the cutting tool engages the workpiece during machining operations. This is a critical parameter as it influences the material removal rate, surface finish, and tool life. Feed rate is typically measured in units such as inches per minute (IPM) or millimeters per minute (MPM), indicating how far the tool moves into the material per unit of time.

In the context of machining, an appropriate feed rate ensures that the correct amount of material is removed efficiently, while also minimizing wear on the tool. If the feed rate is too high, it can lead to poor surface finishes and excessive tool wear; conversely, if it's too low, it may result in inefficient machining and longer cycle times.

Understanding the feed rate and adjusting it correctly is essential for optimizing machining processes and achieving the desired outcomes in production.
