Measurement of the Beruforge 152DL thin-film lubricant using a developed thin-film thickness standard [PDF]
Journal of Sensors and Sensor Systems, 2020 Systematic deviations due to remaining lubricant on the workpiece have a significant influence on the measurement of sheet-bulk metal formed parts. The expected layer thickness for the workpieces after the forming process is less than 35 µm.
