Abstract: An interpolater (3) outputs an interpolation pulse for each axis in response to a movement command. The speed F of a machining head (35) moving along a machining path is calculated from the interpolation pulse (speed) for each axis and is sent to an output condition determination device (4). Based on the speed F, the output condition determination device (4) calculates the corresponding output power M(F), pulse frequency N(F) and pulse duty Q(F) and outputs them. As a result, the beam from a laser oscillator (20) is controlled by the output conditions of M(F), N(F) and Q(F).
