Embodiment 1

[0032] First, refer to Figure 1 to Figure 6 The structure of the three-dimensional laser processing machine of Example 1 of this invention is demonstrated.

[0033] Such as figure 1 As shown, the three-dimensional laser processing machine of this embodiment has: a base 1, which is horizontally arranged on the ground; a door-shaped column 2, which is set across the base 1; a cross rail 3, which is supported on the front surface of the column 2 and can Move along the Z-axis direction (vertical direction) relative to the column 2; the saddle 4 is supported on the rail 3 and can move along the rail 3 in the Y-axis direction (horizontal direction); the ram 5 is carried out by the saddle 4 It can be held and moved relative to the saddle 4 along the Z axis.

[0034] The ram 5 is provided with a laser head 10 that can move along the Z-axis direction relative to the ram 5 and can rotate around the C-axis direction (around an axis parallel to the Z-axis). The head 10 is a laser irra...

Abstract

A three-dimensional laser processing machine that sets the focus position of laser light condensed by a condenser lens at a position at a predetermined distance from a processed part of a workpiece (W), thereby performing high-precision processing on the above-mentioned processed part. The above-mentioned three-dimensional laser processing machine is equipped with a three-dimensional shape measuring device (50) for measuring the three-dimensional shape of the workpiece (W), based on the above-mentioned workpiece (W) measured by the three-dimensional shape measuring device (50) The three-dimensional shape data, and the focus position of the laser light is set at a position at a predetermined distance from the part to be processed.

Description

technical field [0001] The present invention relates to a three-dimensional laser processing machine. Background technique [0002] In recent years, the use of high-tensile steel sheets (high-strength materials) has been expanding and used in various fields. For example, in the automobile industry, in order to improve the fuel economy of automobiles, it is required to reduce the weight of body parts, and to maintain or improve the safety of lightweight body parts, as a way to achieve both weight reduction and high rigidity of body parts. high-strength materials are used. [0003] Body parts and the like made of high-strength materials have very high rigidity compared to conventional parts made of mild steel, making cutting and drilling difficult by conventional press methods. As a result, in parts using high-strength materials, laser cutting and drilling are performed instead of press processing. [0004] The processing by laser is performed by a three-dimensional laser p...
