Advanced Manufacturing Process of Orthotic Shoe Insoles Using A New Material Based on the Taguchi Methodology

Abstract

Some people who have foot deformities such as diabetes often experience pain and difficulty wearing shoes. The optimization of advanced manufacturing based on CAM-CNC with EVA rubber foam material has not been optimal. Two new materials are proposed in this paper for manufacturing optimization through the experimental stage.

Some people who have foot deformities such as diabetes often experience pain and difficulty wearing shoes. The optimization of advanced manufacturing based on CAM-CNC with EVA rubber foam material has not been optimal. Two new materials are proposed in this paper for manufacturing optimization through the experimental stage. The two new materials proposed in this paper provide very significant results when compared with EVA rubber Foam. This new material can reduce the time needed to work on one pair of insoles to 6.0 hours / pair (75% faster) with an average surface smoothness of 7.54µm. The output of this research has significant implications for researchers and the manufacturing industry in the field of the shoe design; optimization of shoe manufacturing on CAM and CNC maching. This research also has implications for the use of modern computer-aided reverse engineering systems.
