Abstract:
1. A method for cutting a structural member using a cutting means acting on a cutting plane and moving along a cutting direction, the method comprising: cutting a first cutting path by positioning the cutting means at a first inclination angle with respect to a longitudinal axis of the structural member and moving the cutting means along the cutting direction parallel to the cutting plane to a set depth of the structural member; cutting a second cutting path by changing the first inclination angle of the cutting plane at least once to a second inclination angle and moving the cutting means along the cutting direction, thus cutting at least half of an entire width of the structural member; and cutting a third cutting path by changing the cutting plane of the cutting means to a third inclination angle with respect to the longitudinal axis of the structural member and moving the cutting means along the cutting direction, thus completely cutting through the structural member.
