PURPOSE:To reduce the cutting form error at the time of the acceleration/ deceleration of work by shifting a working path in cutting direction according to a beam radius. CONSTITUTION:The shift operation in the direction of the Y axis of a working torch is successively performed at prescribed time interval from a first reference point P1 to a second reference point P2 on the work. As the result, a working path PAT turns to be little rising to the right according to the amount of extension of a beam radius W1 in an accelerating area ARE1. It turns to be horizontal in a constant speed area ARE2, further, turns to be a little falling to the right in a deceleration are ARE3. Therefore, even when the beam radius W1 changes accompanied by the transitional change of work cutting speed WCS at the time of cutting the work from the first reference point P1 to the second reference point P2, the influence is rarely exerted on the work part of the lower side of the working path PAT. Therefore, cutting line CL on the side of the products of the work can be linearly cut. |
