On the Cutting Tests of the Small Test Pieces

Minoru Tanaka

Abstract:

Using the small impact and static cutting machines designed by the writer, the cutting energies of metals and alloys, such as lead, tin, aluminum, copper, copper-zinc alloys, tin-lead alloys and lead brass (60% copper, 1∼2% lead) were measured. From the results, it was known (1) that the ratio of the impact and static cutting energies was 1.5∼2.0; (2) that the cutting energy and tensile strength held a inear relation in these metals and alloys except lead brass, (3) that the cutting energy of brass (60% copper) would be decreased by 20∼30% by alloying 1∼2% of lead.
