Milling Speed and Feed Calculator
The RPM calculated in the Mill Speeds and Feeds Calculator refers to the spindle speed in milling process, and IPM refers to feed rate. The exact RPM is not always needed, the following calculator (formula) may be used to estimate the value closely. Cutting speed (SFM): the rate at the workpiece surface, irrespective of the machining operation used. Tool diameter and Cut length in this ...

Projectile Motion
velocity of the ball is determined by shooting it, at the appropriate angle, through 2 photogates that are placed near the muzzle and only a few centimeters apart form each other. Then the initial velocity can be used to calculate where the ball will land when it is shot at some angle . Initial velocity: The photogates are approximately 10 centimeters apart (measure directly to confirm .

The work material has a flow curve defined by K = 275 MPa and n =, and the coefficient of friction between the rolls and the work is assumed to be Determine if the friction is sufficient to permit the rolling operation to be accomplished. If so, calculate the roll force, torque, and horsepower.

For example, the velocity may be about 10 to 20 feet per second ( to m per second). The pressure for this example will be at 3000 psi (207 bar). This pressure is generated by the positivedisplacement pump and by the restriction to flow caused by the valve being forced against the seat by an actuating force. The positivedisplacement pump provides a relatively constant rate of flow .
