Perbandingan Model Data Hilang dengan Model Least Median Square (LMS) pada Optimasi Respon Ganda menggunakan Metode Generalized Reduced Gradient (GRG) (Kasus Penggurdian Komposit Karbon)

Epoxy drillings have consequences the chisel will worn down and drilling result vary greatly. This research purpose is to minimize the chisel wearing out and drilling result deviation with generalized reduce gradient method (GRG). advantage of the method can to look for weighted from both response. This method Applied to outlier data for the chisel wearing out. Research result are more take note of the chisel wearing out than drilling result deviation and optimum condition to machine speed is 715,5 rpm, scrape speed is 90 mm/min, chisel angel is 73,8o with the chisel wearing out is 0,3253 mm and drilling result deviation 5,3720 micron.
