• What is the cutting power required for milling tool steel at a cutting speed of 80m/min. With depth of cut 2mm cutting width 80mm and table feed 280mm/min by Φ250 cutter with 12 inserts. Machine coefficient 80 . Answer First calculate the spindle speed in order to obtain feed per tooth. n=1000vc÷πDC=(1000 80)÷(3.14 250)=101.91min-1

  • This study focuses on developing a good empirical relationship between the cutting force in an end milling operation and the cutting parameters such as speed feed and depth-of-cut by using both multiple regression and neural network modeling processes. A regression model was first fitted to experimentally collected data and any abnormal data points indicated by this analysis were filtered out.
