  • COORDINATE PATTERN FILE CREATION DEVICE, LOCUS PATTERN CREATION DEVICE, AND METHOD OF CONTROLLING LASER PROCESSING MACHINE
    Publication number: 20220410313
    Abstract: An interpolation parameter calculation unit calculates an interpolation parameter of a predetermined interpolation calculation formula based on a first plurality of coordinate values input by means of a coordinate input unit and constituting a coordinate pattern for determining a locus pattern of one cycle when a laser beam is vibrated. A locus pattern calculation unit calculates a second plurality of coordinate values constituting the locus pattern based on an interpolation parameter, respective amplitudes of the locus pattern in an x-axis direction that is a moving direction of a processing head and a y-axis direction that is a direction orthogonal to the x-axis direction, a frequency of the locus pattern, and a control cycle of a beam vibration mechanism for vibrating the laser beam.
