A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
The same principles used in operating a manual machine are used in programming an NC or CNC Machine. The main difference is that instead of cranking handles to position a slide to a certain point, the dimension is stored in the memory of the machine control once. The control will then move the machine to these positions each time the program is ...

operations. In addition to tailoring PowerMILL by the creation of an initialisation macro, you can create macros for undrawing, drawing and resetting leads and links, setting NC preferences, defining regularly used machining sequences, and so on.
In this System the generated power has been directly converted/transformed to 50 Hz, 230/440 V AC, and will be feed to the utilities, thereby reducing the power drawn from the Grid. When the grid fails the output from the wind turbine will also stopped, but the system have the option to auto start a rated capacity Diesel/ LPG Genset.
The operating principle of the pump is to convert mechanical energy to pressure. In operation, a rotating impeller accelerates a liquid and as the area of the pump casing expands the velocity of the fluid is converted to pressure. As a result pressurized fluid exits the pump discharge.
