Milling strategy optimized for orthotics insole to enhance surface roughness and machining time by Taguchi and response surface methodology
The machining strategy of EVA rubber foam for insole shoe orthotics of diabetic patient (ISO-diabetes) by CNC milling is presented in the work. Five parameters such as type of ISO-diabetes (A), toolpath strategy (B), spindle speed (C), step over (D) and feed rate (E) were optimized with Taguchi. Fiv...

Summary: | The machining strategy of EVA rubber foam for insole shoe orthotics of diabetic patient (ISO-diabetes) by CNC milling is presented in the work. Five parameters such as type of ISO-diabetes (A), toolpath strategy (B), spindle speed (C), step over (D) and feed rate (E) were optimized with Taguchi. Five factors that influence the surface roughness value (Ra) and machining time (Ta) were examined using the response surface methodology (RSM). Regression analysis of RSM as a function of machining parameters resulted in the optimum yields of both Ra and Ta. The optimal ISO-diabetes type with a tolerance of 0-2 mm corresponding with the toolpath strategy raster of 45
O
, spindle speed of 14000rpm, feeding rate of 800 mm/rotation, and step over of about 0.2 mm, were reached for Ra of 5.0 μm and Ta of 154.05 s. These optimal conditions could be a promising machining strategy aimed at providing a low-cost manufacturing operation of ISO-diabetes. |
