Why it Works
Customarily during cutoff, either the workpiece rotates and the tool is stationary (single point cutoff) or the tool rotates and the workpiece is stationary (cold sawing). However, RSC brings the advantages of cold sawing to turning applications by having the workpiece and the tool rotate simultaneously. Using a rotating saw in turning applications dramatically reduces chip load because the saw is always cutting a convex shape.
Thus, only one tooth is cutting at a time and it is removing only a small amount of material. Due to the dramatically reduced chip load, workpiece deflection and cutter deflection are insignificant in most cutoff applications.
