Evaluation of a presence sensing switch and new guard design for the AMP electric wire terminating press.
Department of Industrial and Operations Engineering, College of Engineering, University of Michigan, Ann Arbor, Michigan, 1974 Apr; :1-54
Methods of firing an AMP electric wire terminating press were evaluated and ranked as to productivity, quality of terminated wire, and time of learning with respect to the types of machine guarding used. A new guard design was developed. The development of the new guard design was planned to simulate as much as possible the operation of the press with no guard present with the thought that such steps would enable the operator to achieve production rates which would be comparable to those attainable in the unguarded condition. The effects of arm rest influence and workpiece set up and removal on overall production were also evaluated. Removing the operator from having to make any conscious decision regarding actuation of the press allowed the productivity to be greatly increased. In the test conducted in this study the design concepts employed in building the guard enabled the operator to work very nearly to the production level which he would achieve working in an unguarded condition. The new guard was superior in productivity to that obtained using the AMP regular guards. The present sensing switch prevented the operator from inadvertently actuating the press while a guard was present. The use of arm rests appeared to result in productivity increases. The authors propose that the guard which was designed be used in a controlled field study.
