EXPERIMENTAL INVESTIGATION ON DRILLING OF MAGNESIUM ALLOY AZ31B

Drilling is a critical process in the machining industry to obtain good surface integrity. This investigation is forwarded with obtaining better optimal cutting conditions for drilling of Magnesium alloy AZ31B to minimize the Machining time. It is planned to carry out the experiments using Central Composite Design with, TiN coated HSS drill bits of 6 mm size. The test of hypothesis is to be applied to study its influences of drilling process on responses considered. Optimal values of drilling process can be obtained with applying techniques such as GA algorithms.
