A Relationship between Chip Type and Shear Strain,
QUEEN'S UNIV KINGSTON (ONTARIO)
Pagination or Media Count:
Results of experiments are presented in which SAE 1040 steel and 26S aluminum were cut orthogonally using limited-face tools of several face lengths and full face tools with a variety of rake angles. These indicate that the change in chip type from ribbon-like to segmented occurs when the nominal shearing strain reaches a critical value which depends upon the normal stress on the shear plane and is a property of the workpiece material.
