• This research work is related to the comparison of the geometric error of the HU40T five-axis machine tool obtained with a Renishaw ball bar with those from the SAMBA/ TANGO method. The twenty-error parameter gathered from the Renishaw ball bar software in the XY, YZ, and ZX plane are backlash error, lateral play, straightness, scaling error, and squareness error in the X, Y, and Z direction. A compound strategy developed for the SAMBA/ TANGO method uses 21-indexations, one scale and four master balls, and one facet. The reversal and backlash error measured by repeatedly probing the facet with different pre-motion in X, Y, and Z-axis. Finally, the result of the present work shows that the error parameter are not always in good agreement between these two methods. The scaling error parameter in the x-direction EXX was in close agreement. Scaling error values found at -4.65 µm and -4.67 µm in Ball bar and SAMBA/TANGO, respectively. The new technique developed for the estimation of reversal error was useful to obtain the six-reversal error. The four-reversal error was in agreement for the Renishaw ball bar and SAMBA/ TANGO method. The overall obtained measured data shows that the comparison of the Renishaw ball bar and SAMBA/TANGO method is possible for the 9-error parameter out of the 20-selected parameter.
