Abstract

A common setup for industrial machines is to install a pair of actuator buttons a safe distance from the point of operation. Safety codes specify that minimum distance by assuming a constant hand speed of 1.6 m/s. To examine the adequacy of that value, a simulated power press with a moving ram was set up for measuring actual hand speed for three placements of the buttons. For each placement, a randomized complete block experiment with nine students provided after-reach hand speed data. Results indicated that after-reach hand speed is not a constant because it varies both with placement of the buttons and distance within placement.
