Exact stop criterion "Interpolator End"
In the case of the exact stop criterion "interpolator end" the block change to the next
traversing block takes place, as soon as all path axes and special axes involved in the
traversing motion, which do not traverse extending up to block, have reached their position
according to set point programmed in the block. That is, the interpolator has executed the
block.
The actual position and the following error of the relevant machine axes are not taken into
consideration for exact stop criterion "Interpolator end". Thus, depending on the dynamic
response of the machine axes, this can result in a relatively large smoothing of the contour at
the block changes in comparison to the exact stop criteria "Exact stop coarse" and "Exact
stop fine".
Activation of an exact stop criterion
An exact stop criterion is activated in the part program by programming the following G
functions:
G function

Exact stop fine
G602
Exact stop coarse
G603
Interpolator end
Block change depending on exact-stop criteria
The figure below illustrates the block change timing in terms of the selected exact stop
criterion.
