摘要
Tool (20) has body ended by head (20a) having active surface (200) destined to come in contact with a zone of mineral material to work on. Head of tool has first slot (210, 220) opening into active surface for forming, on this active surface, opening (210a, 220a) allowing abrasive particles to be channeled on zone where it collects on active surface, and forming, along this opening on active surface, a cutting edge contributing to desired form. Independent claims are also included for the following : (1) a method for working an optical deformable surface; and, (2) an apparatus for working an optical deformable surface.
