Abstract

The in-process detection of grinding burns has earned considerable interest from both researchers and industries in recent years. Various Non-destructive testing (NDT) technologies, including Eddy Current (EC), Barkhausen Noise (BN), and Acoustic Emission sensors (AE), have been employed to address this issue, yielding successful results for specific applications. However, a comprehensive understanding of burn generation and its prevention in grinding operations remains an area of interest that has not yet been fully resolved.

This paper focuses on investigating the electromagnetic response of a custom-made EC sensor applied to UNE F-522 (AISI 01) steel during in-process inspections. Experimental grinding tests have been performed using a special EC inspection head installed in the grinding machine. The impedance change of the material during grinding is discussed in terms of the machine out-puts (Power consumption) and other grinding variables, such as number of passes, the roughing stock removal, and the finishing strategy. The experimental results demonstrate that the proposed EC technology not only enables the detection of burns, but also enhances comprehension of the surface integrity changes occurring during the grinding process.

通过序中涡流检测分析磨削过程中的表面完整性变化
近年来,磨削过程中的烧伤检测引起了研究人员和工业界的极大兴趣。各种无损检测(NDT)技术,包括涡流(EC)、巴克豪森噪声(BN)和声发射传感器(AE),已被用于解决这一问题,并在特定应用中取得了成功的结果。然而,全面了解磨削操作中的烧损产生及其预防仍是一个尚未完全解决的领域。本文重点研究了 UNE F-522 (AISI 01) 钢在加工过程中进行检测时,定制 EC 传感器的电磁响应。使用安装在磨床上的特殊 EC 检测头进行了磨削试验。磨削过程中材料的阻抗变化与机床输出功率(功耗)和其他磨削变量(如磨削次数、粗加工去毛刺量和精加工策略)有关。实验结果表明,所提出的 EC 技术不仅能检测烧伤,还能更好地理解磨削过程中发生的表面完整性变化。
