It is the method of controlling a machine tool by the application of digital electronic computers and circuitry using alphanumerical data. Machine movements (actuated and controlled by cams, gears, levers, or screws) are directed by computers and digital circuitry. Specific Safety Precautions in Operating CNC Machines.
List Of Non Conventional Mechanical Projects 2017 Unconventional Machining Process Unconventional machining process (or nontraditional machining process) is a special type of machining process in which there is no direct contact between the tool and the workpiece.
Grinding flat or plane surfaces is known as surfaces grinding. Two general types of machines have been developed for this purpose; those of the planer type with a reciprocating table and those having a rotating worktable. Each machine has the possible variation of a horizontal or vertical positioned grinding wheel spindle. The
