6.1.4.3 Tool Center Point (TCP) Calibration
To ensure a Robot can properly perform linear and circular motions, the 
TCP introduced above must be fully defined. In the absence of known tool 
frame properties, TCP Calibration is an operation that accurately 
calculates this data through a series of recorded postures. This procedure 
can calculate the TCP's XYZ coordinates and/or orientation data in the 
flange coordinates.

Coordinates
To calibrate the TCP's XYZ coordinates, five different postures must be 
registered about a reference point with a fine tip (example shown in red in 
fig. 6-15). YASKAWA recommends aligning the first posture of the tool 
with the center of the reference point and then rotating the tool around it 
with significant angle to define the remaining four postures.  See fig. 6-16 
“Calibration Postures” for detail on these postures.
