Optimization of Surface Roughness in Drilling Medium-Density Fiberboard with a Parallel Robot

This study focuses on the examination of effect cutting parameters surface roughness when drilling medium-density fiberboard (MDF) with a parallel robot. Taguchi technique was applied to find optimum and, later, processing. Experimental layout established using L18 orthogonal array, and experimental data were examined via statistical analysis variance (ANOVA). results performed by multiple regression (linear quadratic). Correlation coefficient (R2) found 99.46% for quadratic model. By analysis, values be point angle 118°, speed 47.1 m/min, feed rate 0.01 mm/rev. The optimization outcomes presented that had been successfully decide optimal MDF in drilling.
