Conceptual Design of Special Purpose Machine for Cutting Chases in Wall during Concealed Electrical Fitting

The construction industry worldwide having solid growth due to industrialization, urbanization over the last decade. In survey of these construction sites we found that for concealed electrical fitting the chases cut in the wall is done with help of hand tools like hammer, chisel, grinders, demolition hammer which is very tedious work. Therefore we have designed the wall engraving machine which is based on engraving techniques. With the use of wall engraving machine it is possible to remove the material from wall with ease and giving appropriate straight and clean cut to the wall at specified height for conceal electrical fitting. Our aim of designing this machine is making chases in wall of 30mm deep and 36mm wide in single operation without use of any hand tools so that electrical wires can easily accommodate space. The various parts of this machine like motor, cutter, gears are designed and selected by considering the bricks and concrete strength.
