摘要

在激光切割过程中,无需施加外力即可去除材料,这是它与传统加工方法的不同之处。激光切割的另一个优点是只需一个步骤就能获得所需的表面质量,而无需额外的精加工工序来平滑和清洁切割表面。为确保切割质量,必须全面了解受激光束运动影响的切割部件的热行为。本文重点对厚度为 2 毫米的 AISI 304 钢板的激光切割过程进行了数值模拟,以研究激光切割参数对瞬态热场和切割质量的影响。在使用 Bystronic Bysprint 3015 CO2 激光切割机进行激光切割实验的过程中,通过温度测量建立并验证了模拟模型。ANSYS 软件中的数值模拟用于设计工作图,显示在三种不同切割速度(2000 mm.min-1、4000 mm.min-1 和 5000 mm.min-1)下激光功率与切口宽度之间的关系。

A Simulation Model for the Analysis of Laser Cutting of Stainless Steel Sheets
In laser cutting processes, the removal of material is achieved without the application of external force, distinguishing it from traditional machining methods. An additional advantage of laser cutting is the ability to achieve desired surface quality in a single step, eliminating the need for additional finishing processes to smoothen and clean the cutting surface. To ensure the quality of the resulting cuts, a comprehensive understanding of the thermal behavior of the cut parts, influenced by the movement of the laser beam, is essential. The article focuses on the numerical simulation of the laser cutting process of the AISI 304 steel sheets with a thickness of 2 mm to investigate the impact of laser cutting parameters on transient thermal fields and the quality of the resulting cuts. A simulation model was developed and verified through temperature measurements during an experimental laser cutting process using the Bystronic Bysprint 3015 CO2 Laser Cutting Machine. Numerical simulations in ANSYS software were used to design a working diagram showing the relationship between laser power and cutting kerf width for three different cutting speeds: 2000 mm.min-1, 4000 mm.min-1, and 5000 mm.min-1.

期刊介绍: Defect and Diffusion Forum (formerly Part A of ''''Diffusion and Defect Data'''') is designed for publication of up-to-date scientific research and applied aspects in the area of formation and dissemination of defects in solid materials, including the phenomena of diffusion. In addition to the traditional topic of mass diffusion, the journal is open to papers from the area of heat transfer in solids, liquids and gases, materials and substances. All papers are peer-reviewed and edited. Members of Editorial Boards and Associate Editors are invited to submit papers for publication in “Defect and Diffusion Forum” . Authors retain the right to publish an extended and significantly updated version in another periodical.
