Abstract: An embodiment of the present invention provides a machining system that can lengthen the lifespan of a tool and improve the machining quality of a workpiece by managing the amount of wear of the tool by machining the workpiece using the other portion of the tool when a portion of the tool is worn and the machining performance of the tool is decreased. The machining device for controlling a tool position considering tool wear according to an embodiment of the present invention includes: a tool-moving unit coupled to the machining unit and moving the machining unit to change the position of the tool with respect to the workpiece; a supporting unit supporting the workpiece and moving the workpiece to change the position of the workpiece with respect to the tool; a sensor unit disposed at the machining unit and measuring a current amount, which is supplied to a machining motor operating the tool, or an operation force of the tool; and a control unit receiving a measurement signal from the sensor unit and transmitting a control signal to the tool-moving unit and the supporting unit.

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.
