| Abstract: | Objective To explore the influence of material＇s hardness on clamp trace after the key was copied by key duplicator.Methods Three kinds metal key,iron key,copper key and aluminum key were duplicated on machines,and the clamped trace on original keys then were observed.Result The clamp traces on three kinds material keys were different.Conclusion The key duplicator trace on convexity-tooth key varied with the hardness of the key＇s material. |
