Abstract Scope Experimental scaled modelling in hot forging is recognised to be complex arising out of the non-linear nature of the process. Exact and inexact scaling theories impose a list of various constraints and loading conditions on experiments. The industrial focus of the problem adds additional complications to the design of experiment due to the need of using real forging equipment (e.g. screw or hydraulic presses of different capacities). The technical characteristics of a single press or single testing machine normally provides a very limited range of scaling ratios, as a result, information obtained is difficult to extrapolate to components of significantly different sizes. At the same time, the usage of a few different machines unavoidably introduces a variation in the loading conditions. This paper uses a unique ability of making systematic scaled trials on a few laboratory and industrial forging machines to establish the routes of practical application of the inexact scaling theory introduced in Part I.
