Simulation of manufacturing strategy of an orthotic boots shoe insole product with a Computer-Aided Manufacturing for club foot patient

In this paper, the design of orthotic boots in the club foot patient is investigated concerning the optimum condition of cutting parameters using computer-aided manufacturing. 3D CAD model insole is obtained from the scanning process until the design phase using reverse innovative design method. 3D CAD Model insole is designed using curve Base Modeling. From this design, simulated optimization can be obtained from Computer-Aided Manufacturing (CAM). Optimal manufacturing time optimization is simulated on the CNC Milling machine with the Taguchi approach. Six selected parameters containing toolpath machining, feed rate, spindle speed, depth of cut, Cutter selection, and insole dimension size are of particular interest. It is found that the design layout L2736 gives the most optimal simulation manufacturing using toolpath strategy tep and shallow finishing with spindle speed 1500 rpm, STEPD down 3 mm, Step over 2 mm, and 2mm Cutter diameter, on the model tolerance size 0.75 mm.
