Abstract

PURPOSE:To prevent breakage, failure, etc. of a work by disposing a receiving base which has a through-hole in the direction perpendicular to a working surface and of which the joint surface with a working material is made into a crest shape. CONSTITUTION:The top surface of a member such as Al or the like having a through-hole in a perpendicular direction and having high reflectivity of laser light is formed into a crest shape, by which a receiving base 2 is provided. Since clearances are made between the work and the top surface of the base 2, the reflection of the laser light from the base 2 to the work is prevented. The contact area with the work is a point contact and is therefore considerably decreased by which the chance for reflection of the laser light is decreased as well. The breakdown, discoloration, etc. of the work by the reflection of the laser light are thus prevented.

Description

【発明の詳細な説明】 産業上の利用分野 本発明はレーザ加工装置に関するもので、特に被加工物

ず）を有した平面シート材を受架台１としていた。Configuration of conventional example and its problem 2 As a conventional example for the purpose of preventing laser beam reflection, a flat sheet material having vertical through holes (not shown) is used as shown in Figures 1 and 2 of the drawings. It was used as cradle 1.

壊、破損、変色等の悪影響が起る欠点を有していた。In this case, the joint between the workpiece and the support pedestal 1 is continuous, and the reflection of the laser beam from the support pedestal 1 onto the workpiece occurs for a certain period of time during continuous bending, resulting in damage to the workpiece. It had the disadvantage of causing adverse effects such as destruction, damage, and discoloration.

A shaped receiving pedestal is provided, a sheet-like member such as woven fabric, non-woven fabric, paper, wood, film, leather, etc. is placed on the pedestal, and the focused laser beam is driven or the member on the pedestal is arranged. Cutting is performed by moving the
