2. Speeds and feeds - Wikipedia

   en.wikipedia.org/wiki/Speeds_and_feeds

   A line drawing showing some basic concepts of speeds and feeds in the context of lathe work. The angular velocity of the workpiece (rev/min) is called the "spindle speed" by machinists. Its tangential linear equivalent at the workpiece surface (m/min or sfm) is called the "cutting speed", "surface speed", or simply the "speed" by machinists.

   en.wikipedia.org/wiki/CNC_wood_router

   A CNC metalworking machine with a wood router attached to it, turning it into a makeshift CNC router. Cutting bit rotation speeds on metal working equipment is typically too slow to produce good results in wood. Typical wood piece before router cutting Typical work done by a CNC wood router. A CNC wood router is a CNC router tool that creates ...

4. Machinist calculator - Wikipedia

   en.wikipedia.org/wiki/Machinist_calculator

   A machinist calculator is a hand-held calculator programmed with built-in formulas making it easy and quick for machinists to establish speeds, feeds and time without guesswork or conversion charts. Formulas may include revolutions per minute (RPM), surface feet per minute (SFM), inches per minute (IPM), feed per tooth (FPT). A cut time (CT ...

5. Milling (machining) - Wikipedia

   en.wikipedia.org/wiki/Milling_(machining)

   The speeds and feeds used are varied to suit a combination of variables. The speed at which the piece advances through the cutter is called feed rate , or just feed ; it is most often measured as distance per time (inches per minute [in/min or ipm] or millimeters per minute [mm/min]), although distance per revolution or per cutter tooth are ...

6. Surface feet per minute - Wikipedia

   en.wikipedia.org/wiki/Surface_feet_per_minute

   It relates to spindle speed via variables such as cutter diameter (for rotating cutters) or workpiece diameter (for lathe work). SFM is a combination of diameter and the velocity ( RPM ) of the material measured in feet-per-minute as the spindle of a milling machine or lathe . 1 SFM equals 0.00508 surface meter per second (meter per second, or ...

   In addition, the device must be moved laterally across the work. This is a much slower motion called the feed. The remaining dimension of the cut is the penetration of the cutting tool below the original work surface, reaching the cut's depth. Speed, feed, and depth of cut are called the cutting conditions.
