Line interfaces: Design input
Name outside width and height, wall thickness in millimetres, inside corner radius of the mill tube, permitted face concavity after the bend, CLR, incoming length and whether the long leg must clear the machine during later planes. State parts per hour only with those conditions attached. If several SKUs share the cell, list each section and whether a changeover uses the same clamp die or a second stack. Representative production samples, including the actual mill corner, should be identified for any trial.
Supplier answer
Ask the factory to restate clamp-die contact, wiper support and mandrel shape against the named square section, not against a round-tube diameter row. Confirm which corner geometry and face-distortion limits they will record, and how a long tube is loaded without hitting the pressure die. If a saw or fixture handshake is required, that interface should be marked included, excluded or buyer-supplied. PLC interface language and program transfer belong on the same answer sheet.
