Cutting processing machine and cutting processing method

A cutting processing machine comprising:

• a processing machine body configured to perform cutting processing with a laser beam to a processing object;
• and
• an NC device configured to control the processing machine body;
• wherein
• the NC device comprises:
• a tool radius compensation amount calculator configured to generate tool radius compensation information for correcting a tool diameter of a cutting tool used for performing the cutting processing to the processing object based on a processing program and a processing condition set based on product shape information indicating a size and a shape of a final processed product obtained by performing the cutting processing to the processing object;
• a processing trace calculator configured to generate a tool trace control signal based on the processing program, the processing condition, and the tool radius compensation information;
• and
• a driving controller configured to generate a drive control signal for controlling the processing machine body based on the tool trace control signal;
• wherein
• the processing machine body comprises:
• a processing unit including a tip attached with a nozzle configured to perform the cutting processing to the processing object by changing a position relative to the processing object;
• and
• a tool trace controller configured to control a tool trace that corresponds to the cutting tool and includes a noncircular shape based on the drive control signal, the tool trace forming a shape obtained by oscillating the laser beam in a noncircular oscillation pattern;
• wherein
• the tool trace controller is configured to set, as the processing condition, an offset amount between a control center point that is a reference for controlling the tool trace and a center point of the nozzle;
• the processing trace calculator is configured to generate the tool trace control signal for displacing the control center point relative to the center point of the nozzle by the offset amount in a predetermined direction;
• and
• the processing machine body is configured to control the tool trace based on the drive control signal such that the control center point is displaced relative to the center point of the nozzle in the predetermined direction.
