Burrs Produced by Turning

摘要

Methods were determined for controlling turning-burr size to reduce deburring cost and improve the quality of miniature precision components. A maximum burr height and thickness of 25.4 mu m (0.001 inch) are essential to obtaining consistent deburring and limiting stock loss to 2.54 mu m (0.0001 inch) and edge radii to 76.4 mu m (0.003 inch). Controlling factors include the tool's side-cutting edge angle, back rake, feedrate, and radial depth-of-cut, and the material's strain-hardening exponent and ductility. (ERA citation 04:030785)
