A Prediction Model of Cutting Force about Ball End Milling

Cutting force prediction is very important to optimize machining parameters and monitor machining state. In order to predict cutting force of sculptured surface machining with ball end mill accurately, tool posture, cutting edge, contact state between cutter, and workpiece are studied. Firstly, an instantaneous motion model of ball end mill for sculptured surface is established.

To finish less mass is obtained after milling relative to

To finish, less mass is obtained after milling relative to the original due to leaving certain particles in the mill, sieves, etc. Even when using the brush, not all objects can be separated from the jar and when using the brush to get the mass, more mass can be lost when others are trapped on the surface. Using the modified correlation coefficient R 2, the precision of the model distributions
