What choice of cutting the amount of the three elements of principles?

The back of cut ap feed and cutting speed is cutting the amount of the three elements. Whether it is to improve the cutting speed, or increase the amount of feed and the back of cut, we are able to improve the metal cutting efficiency. However, these three factors, the effect of cutting tool life is the biggest, followed by the feed rate, the minimum amount is back knife. Therefore, the choice of roughing cutting parameters, priority should be given back to using a large knife to eat the amount, followed by consideration of using a large amount of feed, and finally a reasonable cutting speed is selected according to the requirements of tool life. Select principle finishing cutting parameters. Since the semi-finishing, finishing, machining accuracy and surface roughness for higher and more uniform allowance is not yet: Therefore, the choice of cutting the amount of fine cars, we must first ensure the machining accuracy and surface roughness , taking into account the necessary tool life and productivity.
