Abstract
A method and device for cutting materials for manufacturing parts according to which an image of a cutting line is made recurrently downstream from a cutting head. The images produced are analyzed in real time to calculate amplitudes of deviations in the quality of the surface profiles of the cutting line as the part is being cut and comparing the calculated amplitudes to at least one predefined threshold value. The cutting is stopped in the event of the at least one threshold value being exceeded.
Claims15
A method for cutting materials by a cutting machine for a manufacture of parts cut out from the materials, comprising:
- capturing, by a camera, images of a cutting line in a recurrent manner downstream of a cutting head during a cutting operation,
- communicating the captured images to a processing system,
- analyzing, by the processing system, the images thus captured in real time in order to calculate amplitudes of deviations of the cutting line as the cutting out of the parts progresses and to compare said calculated amplitudes with at least one predefined threshold value,
- connecting the processing system to a control system of the cutting machine,
- stopping, by the control system, said cutting operation when said at least one threshold value is exceeded.
A device comprising:
- a cutting machine with a cutting head, configured to cut out material along a cutting line,
- a camera disposed downstream of the cutting head in a direction of progression of a cutting line configured to capture images of said cutting line,
- a communication means configured to communicate the captured images to an analysis system,
- said analysis system configured to analyze the images captured with the camera,
- said analysis system being connected to a control system of the cutting machine in such a manner as to cause instantaneous shutdown of the cutting machine.
