摘要： A cutting machine secures safety of a worker during movement of a head without lowering production efficiency. When moving a cutting head without cutting material to be cut upon a table, a moving truck and the cutting head are moved at a higher speed as compared with when cutting the material to be cut. If, when the moving truck and the cutting head are moving at high speed, a worker who is present upon the table intercepts either of light beams which are located in front of and behind a horizontal beam, then this movement speed is decelerated to a safe low speed, but the task of cutting the material is not interrupted. Subsequently, when the worker approaches the horizontal beam closer, and contacts a wire or a bar in the vicinity of the horizontal beam, movement of the moving truck and the cutting head is forcibly stopped.

摘要： A plasma cutting device performs cutting in a plurality of stages. In a first cutting sub-process, a manufactured product is cut out from a base material upon a stage according to an NC program. Next, images of respective regions in the vicinities of proper positions at two corner points of the manufactured product which has been cut out are photographed by an image sensor, the actual positions of these two corner points of the manufactured product are detected from these images which have been photographed, and the translation distances and the rotational angle between the actual positions which have been detected and the proper positions are calculated. The NC program is corrected. And, in a subsequent cutting sub-process, additional cutting for beveling is carried out upon cutting surfaces at the outer circumference of the manufactured product, according to the corrected NC program.

摘要： Not only damage to a nozzle caused by spatter generated during piercing is prevented but also the deterioration of the nozzle owing to a pilot arc is restrained, whereby the service life of the nozzle is significantly increased. To this end, the plasma torch is positioned at an initial level which is the distance between the plasma torch and a steel plate when generating a plasma arc to start piercing operation and which has been set equal to a cutting level which is the distance between the plasma torch and the steel plate when carrying out cutting operation. After generation of the plasma arc, the plasma torch is immediately raised to a piercing level which is more distant from the steel plate W than the initial level and piercing operation is performed at the piercing level. After completion of the piercing operation, the plasma torch is lowered to the cutting level to start cutting operation. Just after transfer from a pilot arc into a main arc, a pilot current is cut off by turning a transistor off.
