Уплотнение / Упрочнение вроде как не подходит, так как речь в том числе идет и о cutting / bending. Как в глоссарие лучше перевести этот Peening?

peen
1) the end of a hammer head opposite the striking face, often rounded or wedge-shaped
2) to strike with the peen of a hammer or with a stream of metal shot in order to bend or shape (a sheet of metal) •
Etymology: variant of pane, perhaps from French panne , ultimately from Latin pinna point
