the floor!), and twist them around to the proper angle by hand or hoist as was needed to complete the job. If the worker saw an improper cut or bend he or she would "adjust" for the difference by twisting or bending the metal by force. The welder could also compensate for imperfections by adjusting the welding process.

A robot is not able to identify imperfections in the metal sheets and make on-the-spot adjustments. Thus the installation of the robot to weld cabinets dictated that a number of changes be made both upstream of the welding operation as well as in the operation itself. First, the company had to design, acquire, and install a complete set of relatively elaborate fix-turing to hold the metal parts at precisely the right position and angle every time. Second, when two pieces of metal did not match properly, the robot couldn't compensate by bending or twisting the metal until it matched as did a human operator. Thus the company had to buy new shears to cut parts more accurately and a new press brake to bend the metal more precisely.

in all three operations, the robot's speed and accuracy had direct impacts on middle management's planning requirements. For example, management had to be much more accurate in acquiring raw materials as well as maintaining in-process inventory to avoid machine downtime. In addition, materials handling equipment and procedures had to be more closely monitored to ensure compatibility with robot operation.
