摘 要：随着汽车行业的不断发展，整车厂汽车内饰件的质量要求也在不断提升，尤其是软内饰件，其切割工艺关系到零件之间的匹配效果，甚至会影响到最终整车的内饰体验。因此汽车零部件企业在选择切割工艺时往往会从各维度综合考虑，慎重选择。近些年激光切割作为较新颖的工艺，已经在很多行业得到了应用并推广，但在汽车内饰领域还没有得到大范围普及，本文将介绍一种国外引进的激光切割设备，在汽车内饰仪表板的制造应用，并分析其优缺点，给出其使用推广的一些意见。

Application of Laser Cutting in the Field of Automotive Soft Interior Decoration

Zhao Lin

Abstract：With the continuous development of the automotive industry， the quality requirements of automotive interior parts of OEMs are constantly improving， especially for soft interior parts. The cutting process is related to the matching effect between parts， and even affects the final integration and the interior experience of the car. Therefore， auto parts companies often consider comprehensively from various dimensions when choosing a cutting process， and choose carefully. In recent years， laser cutting， as a relatively new process， has been applied and promoted in many industries， but it has not been widely popularized in the field of automotive interiors. This article will introduce a laser cutting equipment imported from abroad， which is used in automotive interiors， the manufacturing and application of the dashboard， and analyze its advantages and disadvantages， and give some opinions on its use and promotion.

1 引言

随着汽车行业的不断发展，汽车整车厂对于零部件尤其是内饰件的质量要求也在不断提升，零件之间的相互匹配除了对成型模具的精度和成型工艺的要求有所提高外，对于一些成型后需要后切割加工的工艺要求也在不断提升，切割工艺的制造精度和稳定性直接影响到零件之间的间隙、面差匹配。目前绝大部分汽车零部件生产厂商使用到的切割工艺主要有冲切、水刀切割、铣刀切割以及激光切割。冲切是一种精度和稳定性相对较好的一种切割工艺，但成本又受制于冲切设备及冲切胎模，一般都是用在量高、节拍要求较快的车型上。水刀、铣刀及激光切割是一种使用工业机器人或数控机床对零件进行切割的工艺，只是切割使用的能量源不同，但整体成本投入和柔性化都较冲切具有一定的优势，只是切割的精度及稳定性不及冲切工艺。……
