The production cycle employs unit operations that are normally grouped into rock breakage and materials handling. Breakage generally consists of drilling and blasting, and materials handling encompasses loading or excavation and haulage (horizontal transport) and sometimes hoisting (vertical or inclined transport). Thus, the basic production cycle consists of these unit operations:

Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a work piece. This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavyduty gang milling operations.

unit or basic operation — is one of the main purposes of food engineering. The systematic study of unit operations began in the chemical engineering field, where calculation tools were developed to describe, based on engineer

A welding power supply is a device that provides or modulates an electric current to perform arc welding. There are multiple arc welding processes in common use ranging from relatively simple Shielded Metal Arc Welding (SMAW) to more complicated welding processes using inert shielding gas like Gas metal arc welding (GMAW) or Gas tungsten arc welding (GTAW).

The CNC machine comprises of the mini computer or the microcomputer that acts as the controller unit of the machine. While in the NC machine the program is fed into the punch cards, in CNC machines the program of instructions is fed directly into the computer via a small board similar to the traditional keyboard. In CNC machine the program is stored in the memory of the computer.

Overview. In 1929, Niels Miller designed a small arc welder for "stick welding" that could operate on the electrical supplies in rural Wisconsin that was lighter and less expensive than the DC rotary units previously available. The first machine was built from recycled scrap steel and coil windings in his basement. In 1935, Miller Electric Mfg. Co. was incorporated.
