Abstract
A drilling work control method includes: automatically discriminating two or more working object layers where load torque applied to a drill forms a hole in a workpiece having plural forming areas formed of materials of different qualities; facilitating drilling work in a working condition set for each working object layer; and improving working efficiency. In a drilling work device that forms the hole in the workpiece having forming layers divided by materials of different qualities, a working object layer determining means determines the layers in order of drilling work based on start of drilling work and variation in load torque applied to the drill, a working condition deciding means decides a set working spindle speed and working feeding speed corresponding to forming materials of the respective layers, and a drive controlling means controls a spindle motor and feeding motor so that the drill forms the hole at the set speeds.
