To improve the accuracy of composite machining by correcting an error which is generated by laser machining in a machining system for performing laser machining and punch machining.
In a machining system for performing laser machining and punch machining, the coordinate system of a machining shaft in the punch machining and the coordinate system of the machining shaft in the laser machining are set, and stored in storage means, and the conversion formula of correction coordinates in the laser machining is set, and stored in the storage means, and a predetermined hole is formed in a work by the punch machining, and the coordinates of the formed hole are stored, and the central position of the hole is measured by detection means in the laser machining. Then, a deviation in a rotation direction between the coordinate system of the machining shaft in the punch machining and the coordinate system of the machining shaft in the laser machining is calculated, and the original point of the coordinate system in the laser machining is calculated, and the coefficients of the gradient correction of the coordinate system in the laser machining are calculated, and the conversion formula of the correction coordinates is read from the storage means, and command coordinates in the laser machining after correction are searched on the basis of the calculated deviation in the rotation direction and the original point of the coordinate system in the laser machining and the coefficients of the gradient correction.
