Understanding the Basics of SFM

Surface Feet per Minute (SFM) is one of the most critical parameters in machining operations. At its core, SFM represents the actual cutting speed at the point where the tool meets the workpiece. Think of it as measuring how fast the cutting edge travels along the surface being cut. For example, if you mark a point on a cutting tool’s edge, SFM tells you how many feet that point would travel in one minute if you could stretch out its circular path into a straight line.

The Role of SFM in Different Materials

Different materials require different SFM values for optimal cutting. Here’s a basic guideline for common materials:

Hi there! I’m Peter,Global Technical Sales Director of PTSMAKE. My journey in the mold and CNC Machining industry started when I was a kid, working alongside my father in the mold workshop. From there, I moved on to becoming a mold designer, then project manager, followed by a sales role, and eventually to PTS partner, all with over 15 years of hands-on experience. I’m here to share what I’ve learned and help take your projects to the next level. Let’s connect and build something great together!
