Abstract
In one aspect the invention relates to a method for calculating control instructions (CI) for controlling a cutting head (H) of a laser machine (L) for cutting a set of contours in a workpiece. The method comprises reading (S71) an encoded cutting plan (P), and continuously determining a state (S73) relating to the processing of the workpiece by the laser machine (L) by means of a set of sensor signals (sens). Further, the method provides a computer-implemented decision agent (DA), which dynamically calculates an action (a) for the machining head (H) to be taken next and based thereon providing control instructions (CI) for executing the processing plan (P) by accessing a trained model with the encoded cutting plan (P) and with the determined state (s).
Claims12
A computer-implemented method for calculating control instructions for controlling a cutting head of a laser machine to execute an encoded cutting plan for cutting a set of contours in a workpiece in order to separate work parts from the workpiece, comprising the method steps of:
- reading the encoded cutting plan which is a sequence of geometrical contours which stand for the work parts including holes in the work parts;
- continuously determining a state by means of a set of sensor signals, wherein the state comprises a state of the laser machine, a state of the cut work parts, and a state of the workpiece to be cut;
- providing a computer-implemented decision agent, which dynamically calculates an action for the cutting head to be taken next and based thereon providing the control instructions for executing the cutting plan by accessing a trained model with the encoded cutting plan and with the determined state,
- wherein the model receives as input the determined state in form of a multi-layer image matrix, and the encoded cutting plan and provides as output an action to be forwarded to a machine controller on the laser machine for being executed next.
