Testing of Tribological Properties of ADI
This experimental work consists of testing of isothermally improved specimens for wear process without lubrication. In the first part investigated was tribological properties on tribometer pin on disc made produced from ADI. Tested was loss of length and loss of mass of pin for different increasing number of revolutions. Both wear parameters were increasing with number of revolutions. In the second part this was accomplished by conducting face milling tests for a range of machining conditions. More specifically, the effects of cutting speed on tool life was tested. In the study was found that the machinability of ADI, in terms of tool life, degrades as the cutting speed increases. Tool wear progression in time cubic polynomial fit equations for workpiece ADI material. The Tool life equation developed by Taylor to quantify the relationship between cutting speed and tool life is determined as well.
