Rough Milling: Speed vs Power | MoldMaking Technology

Feb 01, 2016· For high-speed roughing, width of cut is usually set at somewhere between 5 and 10 percent of the cutting tool diameter This means a 050-inch end mill will be engaged 0025 to 0050 inch This setting will impact RCT calculations as well For example, the average recommended feed rate for a 050-inch tool is approximately 0002 inch per tooth
