Store execution times in R parameters
Task
Store the execution time for part program blocks starting at R parameter 10.
Program
IDS=1 EVERY $AC_TIMEC==0 DO
$AC_MARKER[0] = $AC_MARKER[0] + 1
IDS=2 DO $R[10+$AC_MARKER[0]] =
$AC_TIME
DEFINE INDEX AS $AC_MARKER[0]
IDS=1 EVERY $AC_TIMEC==0 DO INDEX =
INDEX + 1
IDS=2 DO $R[10+INDEX] = $AC_TIME

"Centering" with continuous measurement
Introduction
The gaps between gear teeth are measured sequentially. The gap dimension is calculated
from the sum of all gaps and the number of teeth. The center position sought for continuation
of machining is the position of the first measuring point plus 1/2 the average gap size. The
speed for measurement is selected in order to enable one measured value to be reliably
acquired in each interpolation cycle.
