Cellular Manufacturing Systems

A recent development in manufacturing technology has given rise to a manufacturing concept known as Manufacturing Systems/Cells, or Cellular Manufacturing Systems. These systems of integrated industrial machines, linked by a material handling system and operated by (controlled by) a programmable electronic system (computer) are capable of manufacturing discrete parts or assemblies. The safety of employees exposed to these systems is of first order importance.

Because a system is to be safeguarded it is logical that a system hazard analysis will yield the parameters of the safeguarding system required. Figures 73 through 75 depict typical cellular system concepts and safeguarding considerations.

ANSI B11.20-1991, should be referred to for assistance when a cellular manufacturing system is envisioned.
