Simulation of the cutting action of a single hacksaw blade tooth

The cutting action of tools with very large cutting edge radii has been investigated. These actions have been classified according to the types of chips formed and the variations in the thrust and cutting components of the cutting force obtained. The discussion includes a summary of the implications of the results obtained to the cutting action of power hacksaw blades.

A Sharpening Machine for a New Type of Microtome Knife

ABSTRACT A description is given of the manufacture of a new type of microtome knife made from selected portions of discarded low tungsten steel power hacksaw blades. A machine for sharpening this type of knife is described. Its main feature is a lapping plate of 14 in. plate glass which can be adjusted for height to give cutting angles ranging from 24 to 32°, these angles being accurately reproducible on resharpening. Results of tests with a series of knives covering this range of cutting angles is given.
