Abstract: Optimization of hole-making operations in manufacturing industry plays a vital role. Tool travel and tool switch planning are the two major
issues in hole-making operations. Many industrial applications such as moulds, dies, engine block, automotive parts etc. requires machining of
large number of holes. Large number of machining operations like drilling, enlargement or tapping/reaming are required to achieve the final size
of individual hole, which gives rise to number of possible sequences to complete hole-making operations on the part depending upon the location
of hole and tool sequence to be followed. It is necessary to find the optimal sequence of operations which minimizes the total processing cost of
hole-making operations. In this work, therefore an attempt is made to reduce the total processing cost of hole-making operations by applying
relatively new optimization algorithms known as shuffled frog leaping algorithm and proposed modified shuffled frog leaping algorithm for the
determination of optimal sequence of hole-making operations. An industrial application example of ejector plate of injection mould is considered
in this work to demonstrate the proposed approach. The obtained results by the shuffled frog leaping algorithm and proposed modified shuffled
frog leaping algorithm are compared with each other. It is seen from the obtained results that the results of proposed modified shuffled frog
leaping algorithm are superior to those obtained using shuffled frog leaping algorithm.2016-04-06T00:00:00Z
