Hole Quality Assurance by Optimization of Drilling Parameters Using Cuckoo Search Algorithm

In order to obtain better hole quality (surface finish and hole diameter) in the least possible machining time, a befitting set of drilling parameters has to be identified. Therefore arises the necessity of a technique to devise the methodology for attaining the required set of parameters. Trial experiments were conducted on low carbon steel (SA515gr70) using an indexable drill as a tool. The mathematical modeling was based on experimental values obtained using full factorial DOE. The mathematical models of machining time, surface roughness, hole diameter were expressed a function of the input parameters cutting speed and feed. Cuckoo Search is carried out so as to retrieve the ideal set of drilling parameters to have a minimal machining time in order to get the desired surface finish and hole tolerance. Cuckoo search's ability to predict has been verified and the related results are presented.
