PURPOSE:To prevent excessive heat input and defective cutting by calculating the temperature of each division at a work and determining a target output value of a beam for cutting based on the temperature at the division where a cutting point is located. CONSTITUTION:In the cutting machine 1, the work W is divided into many divisions and in a temperature calculation part 13, various data inputted from a memory 10 for setting a constant, a temperature sensor 12, a memory 14 for storing the temperature, etc., are used to calculate the temperature of each division for every specified time at the time of cutting work. Further, in an output value determination part 15, an output value of the beam V for cutting is determined based on the temperature obtained at the temperature calculation part 13 and a beam generator 2 is controlled according to this output value, by which the excessive heat input to the work W is prevented. |
