Figure 2-18 Twenty-point calibration
The following explains the 20-point calculation results:
Fig. 2-19 Calculation result of 20-point calibration
【
NormErr
】
: Tool coordinate error
【
DeltaDH
】
: Calculated connecting rod parameter error
【
DeltaZero
】
: Calculated zero error
Note: Generally speaking, the value of calibration will not exceed 5mm. If it exceeds
5mm, it may be the problem of joint parameter setting. It is recommended to calibrate after
checking the correctness.
