Measuring principle
The "Measure kinematics" measuring variant always requires the following procedure:
1. Measure a rotary axis
2. Measure a second rotary axis (if this exists)
3. Calculate the swivel data sets (calculate kinematics)
4. The calculated data is activated automatically or with the aid of the user
The user (preferably the machine manufacturer) should ensure compliance with the specified
sequence.
If the position of the calibration sphere within the machine can be specified as an inherent part
of the design, then it will be possible to store the entire kinematic measurement process (carried
out using CYCLE996) as a part program, which is extremely advantageous. As a result, the
user can carry out measurement of the kinematics under a set of predefined conditions at any
given point in time.
The measurement of the rotary axis must be performed in the basic system of the machine.
