Machining a hole or enlarging an existing one with the objective of producing a more accurate hole than by drilling.

A measurement of a metal hardness (or ability to resist penetration). A steel ball is forced into the surface of the material tested under a specific load. The diameter of the depression is measured, [..]

A rectangular step down bar that has the high point near the center.

Steel that owes its properties chiefly to various percentages of carbon with only residual amounts of alloying elements (except those added for composition control such as silicon and manganese).

Process of pouring molten metal into a prepared mold cavity of a desired shape and allowing the metal to solidify.

Casting process that consists of pouring molten metal into the cavity of a rotating mold, which can be made of various materials.
