hip shape in machining of metals not only reflects the quality and success of the operation but also carries the signs about the cutting mechanism. Most importantly, chips are responsible for the heat removal from the cutting zone which directly eliminates the thermal effects such as fatigue, shock, and early failure of edge due to excessive wear. Therefore, analysis of the chips is not only important in these aspects but also have significance in determination of the cutting parameters, lubricating and cooling conditions. This study addresses mentioned points by evaluating the milling parameters under dry cutting conditions to compare chip properties such as color, length, and helix etc. The evaluation was carried out by examining the microscopic images according to the experimentally obtained chips under two different levels of cutting speed, feed rate and depth of cut. The results of this experimental work are expected to be an idea for the future studies in the metal cutting sector.
