Loss of a Degree of Freedom

1238888

In a working volume of the Quantum there can be a loss of a degree of freedom (natural rotation of each joint). With this loss, temporary bending occurs on the transfer tubes of the Quantum causing a movement of the probe position that cannot be recorded by the Quantum’s encoder system. Measurement results taken in these positions are not accurate. This condition is never encountered in the compensation of the Quantum. Common areas of measurement where this loss occurs are:

• when an encoder has reached a hard end stop,

• directly above the Quantum, or

• in close to the base of the Quantum.

The Quantum should always feel fluid in its movement. If excessive force is needed to move to a measuring location, a degree of freedom has probably been lost.
