NEED STATEMENT
The human efforts in electrical wiring are high and the material used for the manufacturing of the wires is costly. Therefore it should be used very effectively. If we want more wires of the same length, we have to measure the wire every time and cut it with a cutter. The same procedure is followed in the stripping of wires also. This needs more manpower/human efforts. Build a semiautomatic wire cutting and stripping machine to minimize human efforts and to avoid the wastage of the wires.
