Answer 1

1.1) Physical vapor deposition

1.2) Ceramic

1.3) Wears out too quickly.

1.4) Cermet

1.5) Toughness

Step-by-step explanation:

1.1) Physical vapor deposition allows evaporated material to condense and solidify on a tool's surface.

1.2) Ceramic cutting tools can maintain hardness at temperatures surpassing 1800°F (982°C).

1.3) A diamond cutting tool wears out quickly when used to machine ferrous workpieces.

1.4) Cermet cutting tool material combines properties that don't typically exist together in individual materials.

1.5) Tool toughness enables shock absorption and resistance to fracture during operation.
