ferrous
a material that contains iron
non-ferrous
a material that does not contain iron
annealing
a heat treatment that makes a metal softer and easier to work
hardening

Manufacturing
The process of making a raw material into a finished product; especially in large quantities.
Working Drawing
Technical graphics that convey all of the information needed to manufacture and assemble a design.
Inorganic Materials (Material Type)
materials that do not come from living organisms
Stainless Steel (Material)
A metal alloy of steel, chromium, and sometimes nickel which is used in casket construction; noted for its ability to resist rust.
Cold Rolled Steel
sheet steel that has been formed using heavy rollers at room temperature, to improve its surface finish, hardness, and strength
Carbon (Material)
Material, makes graphite, coal, and diamonds.
Bore (Drilling Terminology and or Callout)
To make a hole bigger than it already is.
Ream (Drilling Terminology and or Callout)
To drill a hole
Through hole (Drilling Terminology and or Callout)
A hole that goes completely through the workpiece
Countersink (Drilling Terminology and or Callout)
A conical-shaped recess around a hole, often used to receive a tapered screw.
Anodize (Surface Finish)
to coat with a protective oxide layer by an electrolytic process in which the metal forms the anode. (Surface Finish)
Galvanize (Surface Finish)
the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is called _______, in which the parts are submerged in a bath of molten zinc.
casting
The process of pouring molten metal into a hollow cavity and allowing it to cool and solidify into a desired shape. The solid part is known as a casting.
