Usage tips
Word composition
The word is made up of 'vor' (forward) and 'der Schub' (the push/thrust). The literal meaning of a 'push forward' helps you understand both meanings: the figurative one and the technical one.
EXAMPLE
Der automatische Vorschub der Säge muss exakt eingestellt sein.
The automatic feed of the saw must be set precisely.
Fixed expression
The figurative meaning exists almost only in the fixed expression '(einer Sache) Vorschub leisten' (to encourage/promote something). The noun 'Vorschub' is rarely used on its own here. The thing being promoted is in the dative.
EXAMPLE
Mit seiner unklaren Kommunikation leistete er den Gerüchten Vorschub.
With his unclear communication, he encouraged the rumors.
Negative context
The expression 'Vorschub leisten' (to encourage/promote) is used exclusively for negative developments or actions. Typical examples are 'der Korruption Vorschub leisten' (to encourage corruption), 'dem Extremismus Vorschub leisten' (to encourage extremism), or 'dem Missbrauch Vorschub leisten' (to facilitate abuse).
EXAMPLE
Man wirft der Regierung vor, der Spekulation Vorschub zu leisten.
The government is accused of encouraging speculation.
Technical terminology
The meaning related to tool movement is a technical term from technology, especially manufacturing and mechanical engineering. Outside this context, 'Vorschub' (feed) is not used in this sense.
EXAMPLE
Eine hohe Vorschubgeschwindigkeit kann das Werkzeug beschädigen.
A high feed rate can damage the tool.
