What is the difference between “cutting” and a “non-cutting operations”? Cutting operations produce chips during the operation. Non-cutting operations don’t. Name the two geometric edges in “cutting operations”? geometrically defined cutting edges; geometrically undefined cutting edges Which pictures in this chapter show a “cutting operation”? grinding, drilling, flame cutting Which pictures in this chapter show a “non-cutting operation”? water-jet cutting, punching, scissoring Match the following terms: 1. 2. 3. 4. 5. drilling electrical discharge machining (EDM) punching sandblasting laser cutting A B C D E shearing abrading electrochemical heat chip forming What is an important advantage of water-jet cutting? The ability to cut material without interfering with its inherent structure. What is the maximum speed at which water passes through a water-jet nozzle? 3,000 km/hour 07 A2 08 A2 09 A2 10 A2 11 A2 12 A2 13 A2 What I can now do: ●● I know the difference between cutting and non-cutting operations.  ➤ 07 Ich kenne den Unterschied zwischen spanabhebenden und spanlosen Trennverfahren. ●● I can name the two geometric edges for cutting operations.  ➤ 08 Ich kenne die zwei Arten geometrischer Schneiden für Trennverfahren. ●● I can recognise cutting operations.  ➤ 09 Ich kann spanabhebende Trennverfahren erkennen. ●● I can recognise non-cutting operations.  ➤ 10 Ich kann spanlose Trennverfahren erkennen. ●● I can match different operations with their physical phenomena.  ➤ 11 Ich kann unterschiedliche Prozesse ihren physikalischen Phänomenen zuordnen. ●● I know the important advantage of water-jet cutting.  ➤ 12 Ich kenne den wichtigen Vorteil des Wasserschneidens. ●● I know the maximum speed at which water passes a water-jet nozzle.  ➤ 13 Ich kenne die maximal mögliche Geschwindigkeit, mit der Wasser eine Wasserschneiddüse durchströmt. 13 Getting to know cutting and non-cutting operations Check yourself 71 Nur zu Prüfzwecken – Eigentum des Verlags öbv
