Understanding metal flow in aluminium extrusion by means of emptying diagrams
Source abstract
Abstract
Use of emptying diagrams is a useful approach to fully understand the implications of differences in the characteristics of metal flow in metal extrusion processes. The concept of back-calculation of straight transverse lines inside the final extrusion back to their location at earlier stages of extrusion was early developed. When this principle is used to back-calculate a full grid pattern inside an extruded rod back to the initial stage in the unextruded billet; a so-called emptying diagram is obtained. Today such back-calculation is precise, straight-forward and fast by help of FEA. It is shown what kind of information regarding metal flow that can be obtained from emptying diagrams in extrusion processes like forward, backward and hollow profile extrusion.
