Study on Machining Dental Implants by Whirling Approach
A dental implant is an artificial tooth root replacement. The making of titanium alloy dental implants requires a combination of processes such as turning, milling, boring, broaching, and threading. Threading is important since the outer profile of an implant consists mostly of thread. Thread whirling is the chosen process instead of conventional threading. The procedure contains the following advantages: (1)high metal removal rate, (2)good quality, (3)obtaining final profile in one lapse, and (4)long tool life. The research focuses on all aspects of applying thread whirling on the making of dental implant, including theoretical analysis, whirling tool design, and finally cutting procedure. The machining is performed in a Swiss-type lathe, Star SR-20R.
