| Summary: | This paper discusses burr in microdrilling that affect forms and functions of parts. The
effects of microdrillingparameters on burr length and width are identified. The experiment was
conducted using Mikrotools DT110 machine with one millimetre diameter of HSS on copper
workpiece. Burr heights in terms of burr length and burr width were measured by using scanning
electron microscope. The data was analyzed using Taguchi method to find the optimum microdrilling
process parameter for minimizing the burr height. The relationship among spindle speed,
feed rate and burr has been developed. It is found that feed rate is the most influential factors on the
burr height. The desirability of getting the minimum burr height is72% and the optimum parameters
are 30000 rpm spindle speed and 0.2 mm/min feed rate. |
