Title: Describe the formulas for determining speeds and feeds.
Course: Precision Machining Technology I (13203-I) > Section: Exploring the Foundations of Machining

Description should include

- defining rotations per minute (RPM) in terms of precision machining
- consideration of the machining and tooling setup
- the formulas and their variables
- where to locate the speeds and feeds charts containing standard information.

Process/Skill Questions:

- How are the spindle RPM determined for a lathe with a two-inch diameter aluminum shaft?
- What are the inches per minute for a half-inch diameter end mill (two fluted) when cutting aluminum?
