The i ndexing accuracy of the Absodex is the ga p
between the target position set by the NC program and
the actual position.
This t a r g e t p o s i t i o n is t h e a n g l e (sec.) from t h e
standard station (return to origin position)
As shown to the right, the accuracy is calculated from
the target position and the remainder of the actual
result with the smallest and largest value.
A high precision encoder is used to measure the angle.
Repeat accuracy is the maximum dispersion expressed
in a ngle ( s e c . ) wh e n sto p p i n g re p e a t e d l y on the
specified target position under the same condition.
The required accura cy may be repeat or indexing
depending on the characteristics of the machine.
