Processing control device, machine tool, and processing control method

A processing control device to control a tool, comprising:

• a driving device to drive the tool according to a control command;
• an output device;
• a controller to control the driving device and the output device;
• and
• an input device for inputting the control command, wherein
• after preliminary cutting that is cutting processing to be performed on a workpiece on a basis of a preliminary cutting program as the control command is performed before regular cutting processing, the controller generates processing information including a cutting error expected to occur on a workpiece in the regular cutting processing, on a basis of stress that occurs when the tool driven by the driving device touches the workpiece cut on a basis of the preliminary cutting program,
• when a cutting program as the control command for performing the regular cutting processing is inputted from the input device, the controller controls the driving device on a basis of the cutting program,
• when the controller determines that the regular cutting processing based on the cutting program is completed, the controller transmits the processing information to the output device and accordingly the processing information is outputted from the output device so as to be referred by a user, and
• when an error cutting program as the control command for performing cutting processing for correcting the cutting error on a workpiece cut according to the cutting program is inputted from the input device by the user according to the processing information outputted from the output device, the controller controls the driving device according to the error cutting program.

A processing control method in a processing control device including a driving device to drive a tool according to a control command, an output device, and a controller to control the driving device and the output device, and an input device for inputting the control command, the method comprising:

• performing preliminary cutting that is cutting processing to be performed on a workpiece on a basis of a preliminary cutting program as the control command before regular cutting processing;
• generating processing information including a burr position expected to occur on a workpiece in the regular cutting processing, on a basis of stress that occurs when the tool driven by the driving device touches the workpiece cut on a basis of the preliminary cutting program;
• controlling the driving device on a basis of the cutting program when a cutting program as the control command for performing the regular cutting processing is inputted from the input device;
• making the output device output the processing information so as to be referred by a user when the controller determines that the regular cutting processing based on the cutting program is completed;
• and
• controlling the driving device according to a burr cutting program when the burr cutting program as the control command for performing burr cutting on a workpiece cut according to the cutting program is inputted from the input device by the user according to the processing information outputted from the output device.
