4. Main calibration objectives

Calibration is necessary in a number of situations. Generally speaking, it is necessary because of the way in which the robot is programmed, or the way in which its work programs are improved or modified. It may also be necessary for reasons of rapid maintenance, particularly during the robot cell restart phase.

Calibration is therefore essential:

• when PHL programming mode is selected :

  • from a robotic CAD station,

  • from a school station (a cell containing a robot designed to create or develop robotic programs which are then transferred to production robots);

• on robots programmed by learning, which have functions for moving trajectories by translation, rotation, orientation (or mirror effect, which is only...
