| Summary: | Manufacturing processes is needed to form parts such as bone screws.
This paper presents a method of manufacturing conventional bone screw through
machining processes and forging/punching processes. Bone screws used in the
fixation process of bone fractures or cracks on orthopedics implant.
In this study, the design of the screws used for bone fixation process is the
cortical bone screws type. Cortical bone screw has a threaded shaft and along the
full smooth screw head half-ellipse shape. Materials used in the manufacturing
process of the cortical bone screw type stainless steel 316L in which the
machining process using a conventional lathe (CDL 6241, Krisbow, Indonesia)
and for the forging/punching process used our own developed punching machine
based on small and medium-technology industries.
Bone screws produced by machining and forging/punching process is then
performed hardness testing, and testing of surface roughness. The conclusion is
that the bone screw obtained in the research is not significantly different to the
bone screw from AO (Switzerland) / Original
