The shaper is a reciprocating type of machine tool intended primarily to produce flat surfaces. The metal working shaper was developed in the year 1836 by James Nasmyth an Englishman. The Shaper machine tool holds and locates a work piece on a table and machines or cuts the work piece by feeding it against a reciprocating single point cutting tool. When the horizontal surface is being machined the table automatically feeds the work to the cutting tool on each return stroke of google.com, pub-5909580570280809, DIRECT, f08c47fec0942fa0the ram. The surfaces cut by the shaper may be horizontal, vertical or inclined. Principal Parts of a Shaper: The following figure illustrates the different parts of a standard shaper.

PLC TIMING SWICTH
A time switch (also called timer switch or simply timer) is a timer that operates an electric switch controlled by the timing mechanism.
The switch may be connected to a circuit operating from mains power, or for lower-voltage circuits, including battery-operated equipment in vehicles. It may be built into power circuits (as with a central heating timer), plugged into a power point with equipment plugged into the timer instead of directly into the power point, or built into equipment as, for example, a sleep timer that turns off a television receiver after an interval.
