PURPOSE:To shorten the time for machining by deciding whether the region of the parts to be cut corresponds to a range of heat affection or not and determining the cutting sequence of the parts in order of the lower heat affection in accordance with the results of the decision. CONSTITUTION:The cutting sequence of the parts in the case of cutting off the plural parts from one work by a laser beam is determined. The range of the heat affection by cutting with the laser beam is calculated by a means 5 for calculating the heat affection range. Whether the region of the parts to be cut in the work corresponds to the calculated range of the heat affection or not is decided by a means 4 for deciding the heat affection. The cutting sequence of the parts is so controlled by a means 1 for determining the cutting sequence as to be in order of the lower heat affection in accordance with the results of the decision. The operator's burden is decreased in this way. |
