Formulation and Comparison of Experimental based Mathematical Model with Artificial Neural Network Simulation and RSM (Response Surface Methodology) Model for Optimal Performance of Sliver Cutting Operation of Bamboo

Abstract

Bamboo enterprises are continuously sustaining national economy through providing employment opportunities for rural people including raw material collection, processing and marketing. Bamboo has many industrial uses, through this work tried to make the maximum operations feasible so that the machine can prove employment in rural areas at very low manual efforts. This paper reports on design and development of machine with specialty of multiple operations of bamboo processing incorporated in a single machine. It also includes designing of measuring devices for measurement of current drawn, processing torque, Energy, and time required for each processing operations using specially designed electronic kit. The present work reports the design of experimental work to be executed for establishing approximate generalized empirical model for Bamboo(machining properties) processing operations such as cross cutting, external knot removal(two side planning),splitting, internal knot removal, sliver(slats) and stick making, on the basis of experimentation data chosen, using methodology of engineering experimentation. Out of all processing operations, formulation and analysis only for sliver cutting operation is completely mentioned in this paper. The evolution of bamboo machining properties using processing cutters is a complex phenomenon. There are many factors (like geometric variables of machine and bamboo, variation in angular speed, processing torque and variation in current) affecting the performance of bamboo processing machine. This paper presents an experimental investigations and Sequential classical experimentation technique has been used to perform experiments for various sizes of bamboo at different varying speed. An attempt of mini-max principle has been made to optimize the range bound process parameters for minimizing processing torque, Energy, and time required for bamboo Sliver Cutting operation. The test results proved that processing torque, Energy, and time values were significantly influenced by changing important seven dimensionless π terms. The process parameters grouped in π terms were suggested the effective guidelines to the manufacturer for improving productivity by changing any one or all from the available process parameters.
