Our study for the high speed machining of the custom titanium abutment was experimentally performed. The initial drawings for the STL file format was acquired. Tool path generation for the index table and the 3-axis milling machining center with high speed spindle was used considering the tool breakage with tungsten carbide tool of diameter 3mm. The maximum feed rate of 2,600㎜/min and a maximum spindle rpm of 40,000rpm. The machined abutment has the surface roughness of Ra 0.33 ㎛ while the total machining time is less than 1 hour.
