'Maschine' is a very productive base word for many compound nouns that describe devices. Examples are 'Waschmaschine' (washing machine), 'Kaffeemaschine' (coffee machine), 'Spülmaschine' (dishwasher), or 'Bohrmaschine' (drill).

The use of 'Maschine' for an airplane is informal. You can recognize the meaning from verbs like 'starten' (to take off), 'landen' (to land), or from information about the flight destination.

The use of 'Maschine' for a motorcycle is also informal and is often used for large, heavy models. Words like 'fahren' (to ride/drive), 'Biker', or 'Chrom' (chrome) point to this meaning.

When a person is described as a 'Maschine' (machine), it is an informal, usually admiring description of their extreme efficiency or endurance. It emphasizes that the person works or exercises tirelessly like a machine.

'das Tier' and 'die Maschine' can both colloquially describe a very high-performing person. This is not about the literal meaning, because a 'Tier' is a living creature and a 'Maschine' is a device. Figuratively, 'ein Tier' sounds more like great strength, energy, or endurance. 'eine Maschine' emphasizes more that someone works for a long time, reliably, or almost without a break. Learners may confuse the words because both can be meant as praise for strong performance. 'Tier' feels more physical, while 'Maschine' feels more controlled and regular.
