Test report no. PLBO/10: reducing flank wear by controlled elastic deflection of the tool holder

摘要

Cutting tests were carried out on tips of RD 92, cutting EN9 at600 fpm, 0.010 in/rev. feed and 0.10 in. depth of cut, with a standardtool holder and with a tool holder which had been modified in such a wayas to reduce the contact between the clearance face of the tool tip andthe workpiece when the tool holder deflected elastically. The resultsof the tests showed that up to 0.030 in. flank wear the modified tool holdergave tool lives which were about 20% better than those obtained using thestandard tool holder.
