Mill Critical Speed Calculation
The speed of the mill was kept at 63% of the critical speed. The face angle was varied from 90 to 111 degrees for the three types of configuration 1, 2 and 4, as shown in the figure. Also, the height of the lifter bar in configuration 3 was changed to observe the trajectory. It was observed that the ball trajectories could be controlled by the face angle and the height of the lifter bars.

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

ROLLING-(A Brief Guide To Rolling And Rolling Mills)
Rolling mill consists of rolls, bearings, structure, or housing for rigidly supporting these parts, power drive, power transmission system, speed control, roll gap adjusting set up, etc. The force for rolling generally is very high. The power requirements are very high. Hence initial capital investment is high. Rolling mills are generally classified with respect to the number and arrangement

Rolling on Inclined Plane
Rolling on Inclined Plane. Calculation of duration and velocity of an object rolling down a slope ( inclined plane ). Friction is neglected. The velocity is the speed of the object at the length l. Example: at a length of 10 and a height of 5 meters, the angle of slope is 30°, the velocity of a ball is 7.3824 m/s and the time to get there is 2
