Abstract

Influential parameters of the planetary rolling process for the production of copper pipes were initially defined as the reduction of area, feed (α) and inclination (β) angles, material entry rate or input rate, roller’s shape and the rotational speed of the rollers. For evaluating the effects of these parameters, finite element method was selected as the best choice of continuum simulation procedures to reduce costs and save time. Extensive simulations revealed that for any specific reduction of area, feed and inclination angles, there should be a positive correlation between the rotational speed of the rollers and the material input rate for production of geometrically sound copper pipes. This finding brought the possibility of determining the suitable combinations of the influential variables for the production of geometrically sound pipe. These combinations can be summarized as the planetary rolling process windows at different area reductions, varying feed and inclination angles. These process windows show that by increasing the area reduction, the production range of the pipe becomes confined to the limited ranges.
