FIELD: process engineering.
SUBSTANCE: invention relates to metal forming. Sheet workpiece is arranged on rotary mandrel with lengthwise feed of spinning tool made up of forming roller. Said roller is arranged with clearance relative to mandrel. Part metal mechanical properties are adjusted in rotary extrusion with due allowance for thinning for every next part at ith point. Then actual thickness of every next part at ith point is defined to correct clearance between roller and mandrel at point (i+1) of the part.
EFFECT: active adjustment of mechanical properties.
