Manufacturing using groupcells, or cellular manufacturing, would reduce setup time, engineering cost, inventory, productdevelopment time, and purchasing time while simplifying process planning and procurement 1,2.A typical manufacturing laboratory is equipped with rows of identical machines, where studentslearn in sequence from one type of machine to another. Although students would repeat ademonstration and interact with their instructor, they rarely interact among themselves and oftenmiss the link among different processes. The concept of group cell and
