Abstract

The growing availability of metal forming data has driven a new era of data-centric approaches in digital manufacturing. This wealth of data enables the development of digitally enhanced metal forming processes and associated technologies. In this work, using the hot stamping data obtained from a cloud-based manufacturing database, the digital characteristics (DC), defined as the visualisation of a specific manufacturing process containing essential information spanning over the design, manufacturing, and application phases of the products, were unlocked for the hot stamping process. The complex contact conditions were successfully visualised by the hot stamping DC. Following this discovery, the performance of transient lubricant behaviours was evaluated under complex loading and constant loading conditions regarding coefficient of friction evolution and lubricant limit diagram (LLD), which is a digitally-enhanced approach to enable the quantitative evaluation of different lubricants. Results demonstrate that the efficacy of DC-enhanced methodology facilitates the insightful comprehension of transient tribological behaviours and offers great potential on customised lubricant development towards optimisation of hot stamping and metal forming processes.
热冲压过程中复杂载荷条件下瞬态摩擦学行为的数字特性评估方案
越来越多的金属成形数据的可用性推动了以数据为中心的数字制造方法的新时代。这些丰富的数据使数字化增强金属成形工艺和相关技术的发展成为可能。在这项工作中,使用从基于云的制造数据库获得的热冲压数据,为热冲压过程解锁了数字特征(DC),定义为包含跨越产品的设计,制造和应用阶段的基本信息的特定制造过程的可视化。通过热冲压直流成功地实现了复杂接触条件的可视化。根据这一发现,在复杂载荷和恒定载荷条件下,通过摩擦演化系数和润滑剂极限图(LLD)对瞬态润滑剂的性能进行了评估,这是一种数字化增强方法,可以对不同润滑剂进行定量评估。结果表明,直流增强方法的有效性促进了对瞬态摩擦学行为的深刻理解,并为优化热冲压和金属成形工艺的定制润滑剂开发提供了巨大的潜力。
