The present invention provides a method for manufacturing a decoration stone for an exterior wall. The method for manufacturing a decoration stone for an exterior wall comprises: a primary process step of processing an original rectangular parallelepiped stone to be a primarily processed rectangular parallelepiped stone, the primarily processed rectangular parallelepiped stone having a cylindrical hollow formed in a center thereof and having a center equal to centers of the upper surface and a lower surface thereof; a secondary process step of cutting the primarily processed rectangular parallelepiped stone along a straight line, which connects the centers of the upper surface of the lower surface in opposite to each other, into four parts, thereby obtaining each secondarily processed stone; a third process step of cutting the secondarily processed stone along a first inner cutting line formed on the upper surface and lower surface of the secondarily processed stone, which is perpendicularly to a first cutting line, and cutting the secondarily processed stone along a second inner cutting line formed on the upper surface and the lower surface of the secondarily processed stone, the second inner cutting line extended from one end of the first inner cutting line in a direction of a curved line of the upper surface and the lower surface of the secondarily processed stone, thereby obtaining a thirdly processed stone; a fourth process step of performing a process equal to the third process step based on the second cutting line. According to the present invention, the decoration stone for the exterior wall can be easily and conveniently manufactured, and waste of material can be prevented, thereby achieving economic efficiency. |
