Optimization of Parameter for Cutting Condition of Uhmwpe Acetabular Cup Based On Taguchi and Desirability Functions

Abstract

AbstractThe use of CNC milling machines in the manufacturing industry contributes significantly to producing according to the shape desired by the consumer. It is, however, possible to determine the product quality from the amount of surface roughness and optimal processing time. UHMWPE acetabular cup is a product component that requires excellent machinability and manufacturing quality. Taguchi and desirability function methods were used in this study to determine the optimal cutting parameter conditions and data response to produce acetabular cup products. The four parameters were applied to determine the significant effect on surface roughness response and processing time, while the experimental layout used was L934. The results showed the optimal machining parameters in the inner and outer acetabular cup product manufacturing process were able to produce an optimum Ra inner value of 0.881 µm and Tm. Inner of 1746.37 sec, Ra outer value of 0.928 µm, and Tm Outer of 942.21 sec.
