Paper Title
Tool Path Planning for Hole Making Operations Using Real Coded Genetic Algorithm

Abstract
Tool path planning is very crucial for multiple hole drilling of different diameters as in case of moulds, dies, etc. This problem is more challenging to solve as it combines two objectives which are conflicting in nature.The first one is to minimize the total distance travelled for drilling all holes (like travelling salesman problem) and the second one is to minimize tool switching time if the next hole to be drilled is of different diameter. Usually, manual trial and error approach or the heuristic algorithms are used to obtain the solution of such problems. However, these methods do not guarantee the best solution. In this work therefore a metaheuristic known as real coded genetic algorithm is employed to solve this problem. The steps of implementation of real coded genetic algorithm are discussed through a simple application example.
