Machining method, machining apparatus, and machining program

A machining apparatus for machining a workpiece, comprising:

• a workpiece spindle configured to drive the workpiece to rotate,
• a laser head configured to supply a powder material to the workpiece and perform additive manufacturing by irradiating the workpiece with a laser beam,
• a tool rest configured to hold a tool, and
• a control unit configured to control the machining apparatus,
• wherein the control unit is further configured to execute
• processing of causing the workpiece spindle to rotate the workpiece, and
• processing of performing simultaneous machining in which additive manufacturing performed by the laser head and turning performed by the tool are performed simultaneously on the rotating workpiece, and
• the simultaneous machining is performed in a state in which an additive manufacturing point, at which the laser head performs additive manufacturing on the workpiece, and a turning point, at which the tool performs turning on the workpiece, are separated by a predetermined distance or more in a rotation axis direction of the workpiece spindle while the laser head and the tool are fed to one side in the rotation axis direction.

A non-transitory recording medium storing a machining program to be executed by a machining apparatus for machining a workpiece,

• the machining apparatus including
• a workpiece spindle configured to drive the workpiece to rotate,
• a laser head configured to supply a powder material to the workpiece and perform additive manufacturing by irradiating the workpiece with a laser beam, and
• a tool rest configured to hold a tool,
• wherein the machining program causes the machining apparatus to execute
• a step of causing the workpiece spindle to rotate the workpiece, and
• a step of performing simultaneous machining in which additive manufacturing performed by the laser head and turning performed by the tool are performed simultaneously on the rotating workpiece, and
• the simultaneous machining is performed in a state in which an additive manufacturing point, at which the laser head performs additive manufacturing on the workpiece, and a turning point, at which the tool performs turning on the workpiece, are separated by a predetermined distance or more in a rotation axis direction of the workpiece spindle while the laser head and the tool are fed to one side in the rotation axis direction.
