Abstract:
1. A method of pulsed machining of a contour of a workpiece with a beam tool, the method comprising the step of: pulsing a beam tool and creating a movement between the beam tool and a workpiece to machine a predefined contour of the workpiece, the pulsing and the creating a movement being such that an instantaneous frequency ratio φ of a pulse frequency f L of the beam tool and a rotational frequency f CNC is adjusted in such a way that machining pulses are distributed in a number of locations along the predefined contour of the workpiece, the rotational frequency f CNC being one of a rotational frequency of the beam tool with respect to the predefined workpiece contour or a rotational frequency of the predefined workpiece contour with respect to the beam tool; and setting the frequency ratio φ as an irrational number or setting the frequency ratio φ as a quotient U/k, where U and k are prime numbers.
