Abstract

Too/marks produced by 44 sequentially manufactured screwdriver tips have been characterized for surface roughness using a pro.filometer. Too/marks were produced in lead at angles of 30 o, 60 o, and 85 °. A computer program developed to compare and match the pro.filometer data has been used to show that marks from a single tip produced at similar angles yield much higher correlation values than marks produced from the same tip but at different angles. This analysis provides statistical support for the widely-accepted empirical observation that too/mark striae must be reproduced at similar angles in order to be unambiguously identified as being made by a particular tool.
