In the tooling industries, AISI H13 die steel offers enormous opportunities in dies manufacturing owing to their outstanding thermo-mechanical properties. Unfortunately, their low thermal conductivity causes various challenges one of the grinding burn. Besides, non-destructive finished surface characterization is important consideration from an economical, faster, and in-line quality assurance perspective. Such a serious issue was tackled by sustainable grinding with non-destructive characterization. The objective of the current investigation is to assess grinding burn regions of ground surface using micro-magnetic Barkhausen noise (MBN) signal after minimum quantity lubrication (MQL) grinding. The MQL grinding was performed at downfeed 32 µm with MQL castor oil, MQL-CO+DIW emulsion, and MQL-Al2O3 NFs and compared with traditional grinding, i.e., wet and dry. Negligible grinding burn effect was found in ground sample, which provides lower roughness, no oxidation of microchip, minor microstructural, and hardness variation under MQL-Al2O3 NFs. The MBN results like root mean square were established a linear trend with hardness and its R2 of 0.989. Furthermore, smaller amplitude and broad peaks were moved towards stronger magnetic field in the MQL-Al2O3 NFs grinding.

摘要

In the tooling industries, AISI H13 die steel offers enormous opportunities in dies manufacturing owing to their outstanding thermo-mechanical properties. Unfortunately, their low thermal conductivity causes various challenges one of the grinding burn. Besides, non-destructive finished surface characterization is important consideration from an economical, faster, and in-line quality assurance perspective. Such a serious issue was tackled by sustainable grinding with non-destructive characterization. The objective of the current investigation is to assess grinding burn regions of ground surface using micro-magnetic Barkhausen noise (MBN) signal after minimum quantity lubrication (MQL) grinding. The MQL grinding was performed at downfeed 32 µm with MQL castor oil, MQL-CO+DIW emulsion, and MQL-Al2O3 NFs and compared with traditional grinding, i.e., wet and dry. Negligible grinding burn effect was found in ground sample, which provides lower roughness, no oxidation of microchip, minor microstructural, and hardness variation under MQL-Al2O3 NFs. The MBN results like root mean square were established a linear trend with hardness and its R2 of 0.989. Furthermore, smaller amplitude and broad peaks were moved towards stronger magnetic field in the MQL-Al2O3 NFs grinding.
