Manufacturing And Production Technology A CNC vertical milling machine has to cut a straight slot of 10 mm width and 2 mm depth by a cutter of 10 mm diameter between points (0,0) and (100,100) on the XY plane (dimensions in mm). The feed rate used for milling is 50 mm/min, milling time for the slot (in seconds) is 180 170 240 120 180 170 240 120 ANSWER DOWNLOAD EXAMIANS APP
Manufacturing And Production Technology The relation between tool life (T) and cutting speed (V) is VTn = Constant. In this relation, the value of n depends upon Work material Type of chip produced Working conditions Tool material Work material Type of chip produced Working conditions Tool material ANSWER DOWNLOAD EXAMIANS APP
Manufacturing And Production Technology The tool life is said to be over if Overheating and fuming due to heat of friction starts Poor surface finish is obtained All of these There is sudden increase in cutting forces and power consumption Overheating and fuming due to heat of friction starts Poor surface finish is obtained All of these There is sudden increase in cutting forces and power consumption ANSWER DOWNLOAD EXAMIANS APP
