Abstract
A transfer line apparatus for performing multiple machining operations on each of a plurality of workpieces in a transfer line. The apparatus includes a plurality of different kinds of machining units disposed at respective machining stations along a transfer path. A workpiece transporter moves workpieces along the transfer path to position each of the workpieces at each of the machining stations and allow each of the machining units to machine each of the workpieces as the workpieces move along the transfer path. A controller connected to the machining units responds to an inspection command by causing all machining units downstream from a designated machining unit along the transfer path to allow a workpiece selected for inspection to pass by without being machined by the downstream units. This allows the workpiece to be inspected in a form that the remaining machining units have not altered.
