Corrugations (Fins) The main use is to permit migration of fluid across fin channels, usually in boiling duties. Serrated corrugation is made by cutting the fins every 3.2 mm and displacing the second fin to a point half way between the preceding fins. This gives a dramatic increase in heat transfer.

cut finish and, ultimately, tool life. Poor maintenance of gibs and slides causes the toolholder to bend under load. This changes the attack angle between the tool and the tube or pipe, and it affects the tooling work load. Cutting with a shallower angle of attack (that is, an angle that is more laid back against the direction of travel) puts a lower scarf-
