3D - FEM simulation was used as an efficient tool for description of stress-deformation thermal field at rolling of tubes on a pilgrim mill. The monitored objectives comprised also behaviour of working tools at this rolling. This paper assumes rolling of already pierced thick-walled blank. which passes through the pilgrim stand at simultaneous reduction of thickness of inside and outs... https://www.bellfordtoysandhobbiers.shop/product-category/wooden-kit/
