Title:
LASER MACHINING SIMULATION METHOD, LASER MACHINING SYSTEM HAVING MEANS FOR IMPLEMENTING THE METHOD, AND COMPUTER PROGRAM FOR IMPLEMENTING THIS METHOD
Document Type and Number:
WIPO Patent Application WO/2019/145515
Kind Code:
A3
Abstract:
The present application relates to a method for simulating a laser machining process of a material by a laser machining system, the method comprising the following steps: supplying to a central unit: - information relating to the material to be machined: delta δ, threshold fluence, incubation coefficient S, complex refractive index n + ik; - information relating to the laser machining system: information relating to the polarisation, the pulse energy Ep, the diameter of the machining laser beam at a focal point w, a Gaussian order p, the pulse repetition rate PRR of n pulses, the wavelength; determining, by means of the central unit and on the basis of the information relating to the material to be machined and to the laser machining system, a two-dimensional machining profile corresponding to the simulation of a machining process of the material to be machined using the laser machining system.
