Every now and then we like to go to square one to discuss some fundamental issues surrounding the work done in the average machine shop. This episode is one of those episodes. Jim and Jason are talking SFPM - Surface Feet Per Minute in this episode. If you don’t understand what SFPM is, or if you don’t know how to calculate it, you need to listen in to this episode.

Properly calculating SFPM is a fundamental machine shop skill that enables you to do a handful of very important things:

* You’re able to optimize the work-flow of your shop.

* You do that by maximizing the rate at which you are making chips.

* This results in more money being made per minute.

* It also saves tools, materials, and time.

Every machinist, from novice to experienced must understand how to calculate Surface Feet Per Minute in order to do the very best job with every piece of material and with every tool. Without this knowledge they will wear out tools, destroy materials, and ultimately cost the company money, simply because of ignorance of this fundamental skill.

In this episode of Making Chips Jim and Jason also give some examples of how they go about managing the issue of SFPM in their shops, including the kind of conversations they have with employees about SFPM, how they can tell if SFPM has not been calculated accurately, and how to do the actual math to determine a proper SFPM number for the material and tools being used.

Yep, it’s basics. But the basics are important. So get ready to review (or learn for the first time) on this episode of MakingChips.
