Abstract: Provided is a machining method for improving machining quality for a machining target by minimizing vibrations occurring during machining of each machining region, deformation of a shape of the machining region, and a position error of the machining region by selecting a machining path in consideration of the number of fixing jigs and a distance between jigs at each machining region. A method for machining a carbon fiber reinforced plastic (CFRP) using a machining path and a machining order in view of a jig arrangement includes i) an operation in which shape data of a machining target is input to a controller ii) an operation in which a position of each of a plurality of flexible jigs is controlled, iii) an operation in which when the machining target is seated on the flexible jig, position information of the machining target in contact with each of the flexible jigs is generated and transferred to the controller, iv) an operation in which the controller generates a machining path according to a start machining region and a machining order for the machining target by comparing the input position of the flexible jig with position and shape data of the machining target, and v) performing machining, by a tool, on the machining target.
