Tubular wax and lead specimens were elongated in an Assel, 3‐roll oblique system to estimate the incidence of unnecessary macroshear strain, on the one hand, and the correlation between force and torque parameters and the redundancy of the system on the other. The effect of pass geometry on the material response was tested against the conditions created by the “theoretical” roll profiles – designed in accordance with the CRHS concept – and those produced by the standard, industrial passes.
