The correct way of splitting tools - Optimization of instrument design for measuring contact stress distribution

Laakso, Sampsa V.A. LU ; Bushlya, Volodymyr LU and Ståhl, Jan Eric LU (2018) In Procedia Manufacturing 25. p.97-102
Abstract

Contact stress on the tool has been measured with a split-tool apparatus that has a poor resolution of the stress distribution, and with photoelastic tools that cannot be used with real cutting parameters since the materials are too weak. This paper presents an improved split-tool design allowing continuous stress distribution dataset instead of discreet steps by using a tilted separation plane between the tool tip and the tool body. This paper optimizes the separation plane angle with 3D-FEM to minimize deflection.
