likely be the waste of waiting by the operator. The operator may perform mis-
cellaneous tasks to “keep busy,” such as getting the next parts ready or “organ-
izing” the work area (we observed one operator neatly restacking every part in
the bin, which looked nice but was of no value). It is not clear what the cycle
time of the robot is. The Standardized Work Combination Table (Figure 6-6) is
useful for this situation.
Figure 6-6 shows the same job depicted on a Standardized Work Combination
Table. Read it by following the work elements one by one from left to right, and
you can see where in the cycle the operator walks to perform the next work
element. In this example the operator picks up Bracket Ain one second, walks
to the machine in two seconds, loads Bracket Ain six seconds, walks to get the
next part in two seconds, and so on. By Step 11 all of the parts are loaded into
the robotic welder, and you see by the dotted line that the machine cycles for 23
seconds.
