By\u0000 interpreting the data-driven metamodels using explainable machine learning\u0000 techniques, the effects of the hard-to-measure material parameters during the\u0000 clinching are studied. It is demonstrated that the friction between the two\u0000 metal sheets and the flow stress of the material at high (up to 100%) plastic\u0000 strain are the most influential factors on the interlock and the neck thickness\u0000 of the clinching joints.

First, while the friction between the two metal sheets\u0000 promotes the formation of the interlock, it reduces the neck thickness and thus\u0000 increases the risk of breaking in this region. Second, it is easier to form the\u0000 interlock if the deformed material exhibits small flow stress at high plastic\u0000 strain, but the neck thickness tends to be thinner in this case. The identified\u0000 material parameters help to significantly reduce the relative error between the\u0000 simulated results and the experimental results, not only in the configurations\u0000 from which they are identified but also in a new configuration.

We\u0000 carefully looked into four important process parameters: stand-off distance\u0000 (SOD), water pressure (WP), traverse rate (TR), and abrasive mass flow rate\u0000 (AMFR). The results showed that as SOD goes up, the kerf taper angle goes up\u0000 because of jet dispersion, but as WP goes up, the angle goes down because jet\u0000 kinetic energy goes up. The TR was directly related to the kerf taper angle, but\u0000 it made the process less stable. The kerf drop angle was not greatly changed by\u0000 AMFR. When it came to kerf top width, SOD made it wider, WP made it narrower, TR\u0000 made it narrower, and AMFR made it a little wider.
