The cutting edges of cutting tools don’t actually produce chips. Instead, the pressure of a rapidly spinning tool on a workpiece plasticizes part of the parent material, creating a shearing effect that forces the material to ride up the tool. The flute and tool geometries form the chip and force it away from the tool body until it breaks off and evacuates.
Iscar Metals Inc. produced this video depicting this process.
Cutting Tool Engineering cited the video in the October 2016 Get With The Program column, "Bring on the Heat," which offers a heightened appreciation for the roles that machining parameters and heat play when cutting metal.
