Аналіз наукових публікацій дозволив виявити, що проблема підвищення коефіцієнта використання матеріалу при виготовленні східчастих обичайок на сьогодні не вирішена повністю. Відомі технологічні процеси кування великих обичайок полягають у закриванні уступів технологічним напуском на механічну обробку. Це приводить до зайвих витрат матеріалу, а також розрізування внутрішньої волокнистої структури. Моделювання дозволило встановити, що кування східчастим бойком призводить утворення конусності на обичайках. Макроструктурне дослідження дозволило визначити, що процес кування таких поковок східчастим бойком призводить до утворення волокнистої будови, яка повторює контур східчастої деталі.
