Keywords:
Bandsaw machine, Top arm angle, Material removal Rate, Cut quality (Taper), Taguchi method, Grey relational analysis, ANOVAAbstract
Cutting of raw material is a basic process to cut material to required length for further operations. But compared to other cutting off processes, like hacksawing, parting, shearing etc., bandsawing process has not attracted researchers. Now a days bandsaw machines are used to cut the material instead of hacksaw due to the demand of fast and accurate cutting to feed the CNC machines for subsequent operation. Looking to the increased use of bandsaw in industries, optimization of its cutting parameter becomes vital for researcher to study and suggest appropriate optimal combinations. In the present study “Material removal rate (MRR)” and “cut quality (Taper cutting)” are focused to optimize. With the help of Taguchi method experiments are planned and response parameters are recorded. An approach to use Taguchi and “Grey relational analysis” together to optimize process parameters for multiple response in bandsawing operation is discussed in the present work. The results show that speed and top arm angle has significant effect on the response parameters. The significance and contribution of individual parameter to the response is calculated using ANOVA. Detailed experimentation and result analysis is presented in this study
