<P>PROBLEM TO BE SOLVED: To achieve the movement of a machining point of a machining head stably at a high speed. <P>SOLUTION: An offset-type machining head 2 capable of relatively moving in an X-axis direction and in a Y-axis direction with respect to an XY plane is provided rotatably around a C-axis 13 perpendicular to the XY plane, and a machining point P of the machining head 2 away from the center line of the C-axis 13 by an offset distance r is determined relatively by the movement in the X-axis direction and in the Y-axis direction by the linear motion of the machining head 2 and the movement in the X-axis direction and in the Y-axis direction by the rotational motion around the C-axis of the machining head 2. A coordinate (x, y) of the machining point P of the machining head 2 is obtained from a calculation formulas x=x1+x2 and y=y1+y2, and x2 and y2 are obtained by the calculation of a trigonometric function of the offset distance r of the machining head 2 and a rotation angle θ around the C-axis. <P>COPYRIGHT: (C)2013,JPO&INPIT |
