Abstract

This laser processing device comprises a processing pattern input unit, a two-dimensional display unit, a three-dimensional position display data generation unit for generating three-dimensional position display data compatible with three-dimensional display, a profile information input unit, a three-dimensional display unit, a processing-condition-setting unit for displaying the position of a processing pattern on a surface being processed by using the three-dimensional position display data and setting a processing condition as position information, and a three-dimensional laser processing control data generation unit for generating three-dimensional laser processing control data in accordance with the processing condition. The processing condition is edited after display is carried out such that the processing pattern is replaced with three-dimensional position display data having a smaller data volume by a setting terminal; therefore, it is possible to smoothly edit the processing condition.

Dependent claims

A laser processing device configured to emit a laser beam to a processing subject surface of a workpiece arranged in a working area and perform processing based on a set processing pattern, wherein the laser processing device includes a laser beam source that generates a processing laser beam, a scanner that scans the working area with the processing laser beam emitted from the laser beam source, and a controller that controls the laser beam source and the scanner, the laser processing comprising:

a processing pattern input unit to which the processing pattern is input as two-dimensional information;
a two-dimension displaying unit for displaying a screen used to edit the processing pattern input from the processing pattern input unit;
a three-dimensional positioning data representation generator for generating a three-dimensional positioning data representation corresponding to a three-dimensional representation representing a printing area of the processing pattern edited on the screen displayed by the two-dimension displaying unit;
a profile information input unit to which profile information representing a three-dimensional shape of a processing subject surface is input;
a three-dimension displaying unit for displaying a screen for editing the profile information input from the profile information input unit;
a processing condition setting unit for setting a processing condition as position information on the screen displayed by the three-dimension displaying unit by representing a position of the processing pattern with the three-dimensional positioning data representation on the processing subject surface shown based on the profile information;
and
a three-dimensional laser processing control data generator for generating three-dimensional laser processing control data used to process the processing subject surface based on the processing pattern in accordance with the processing condition set by the processing condition setting unit.
