On the one hand, collision energy produced by falling impact of ball is one of the important parameters for ball milling. Therefore, during WBM, the impact force of the ball on powders is weakening due to the resistance of liquid to falling ball. The lower impact force of the ball influences particle size of both reinforcements and matrix.

The end mill speed is calculated with the following formula: n [rpm] = (vc [m/min] *1000) / 3.14 * ø d1 [mm]) Example calculation: vc = 500 m/min (selected from chart) d = ø 8 mm 19904 rpm = (500 *1000) / (3.14 * 8). If the maximum speed of the milling motor is lower than the calculated value, the maximum speed of the milling motor needs to be inserted into the formula for the feed calculation.
