Licensee MDPI, Basel, Switzerland.Automotive, railway and aerospace sectors require a high level of quality on the thread profiles in their manufacturing systems knowing that the tapping process is a complex manufacturing process and the last operation in a manufacturing cell. Therefore, a multivariate statistical process control chart, for each tap, is presented based on the principal components of the torque signal directly measured from spindle motor drive to diagnosis the thread profile quality. This on-line multivariate control chart has implemented an alarm to avoid defected screw threads (oversized). Therefore, it could work automatically without any operator intervention assessing the thread quality and the safety is guaranteed during the tapping process.18880534enginfo:eu-repo/semantics/openAccessjournal article10.3390/met11040537Sculptured surface machiningTappingOver-sizedMonitoringWearTribologyHigh speed steelSculptured surface machiningTappingOver-sizedMonitoringWearTribologyHigh speed steelGeneral Materials ScienceMetals and AlloysSDG 9 - Industry, Innovation, and InfrastructureProject IDinfo:eu-repo/grantAgreement/EC/H2020/723698/EU/Integrated Zero Defect Manufacturing Solution for High Value Adding Multi-stage Manufacturing systems/ForZDMinfo:eu-repo/grantAgreement/EC/H2020/723698/EU/Integrated Zero Defect Manufacturing Solution for High Value Adding Multi-stage Manufacturing systems/ForZDMFunding InfoThis research was funded by the vice-counselling of technology, innovation and competitiveness of the Basque Government grant agreements IG-2011/0000392, ZL-2019/00720 (HARDCRAFT project) and KK-2019/00004 (PROCODA project).
