Abstract: A cylindrical member is placed in a dead-end hole formed in a housing made of a material such as aluminum. A peripheral portion of the hole is pressed down to plastically deform the housing material and to supply the deformed material into a groove formed on an outer periphery of the cylindrical member. The cylindrical member is calked to the housing in this manner. To supply a proper amount of deformed material into the groove for obtaining a quality calking, an inflection point of a calking curve indicating a relation of a calking force and a calking stroke is detected during the calking process. After the inflection point is detected, the calking is performed by giving a predetermined calking stroke or by adding a predetermined calking force.

Abstract: Various models of brake parts (products) are produced with a mixedly transferring production system. The mixedly transferring production system includes a top line, a first production line, a second production line, and a third production line, a mixedly transferring depot, a part depot, and a set assembling line, and a product depot (mentioned in order of processing flow). Out of them, the first to third production lines, the mixedly transferring depot form the mixedly transferring block division type of production system. In addition, an averaging post and a production order plate (kanban) sorter are provided (mentioned in order of production command flow).
