摘要
Investigations of heat flow through bonded and brazed tools have shown that temperature is higher in the bonded tool at the tool tip. This in turn may cause destabilization in the micro-structure of temperature-sensitive workpieces. In the present work, Duralumin, being a temperature-sensitive heat treatable Al-Cu alloy, is machined with both bonded and brazed tools. The correlation between cutting temperature, micro-hardness and photomicrographs reveals that phase stability of Duralumin is always maintained with bonded tools. This renders bonded tools safe for machining temperature-sensitive heat treatable alloys.
