Leitreihen
Leitreihen, a German term roughly translating to "leading series" or "reference series," is a concept used in various fields, particularly in engineering and design, to denote a standardized sequence of values or dimensions. The primary purpose of a Leitreihe is to simplify design processes and ensure interchangeability and compatibility between components. Instead of allowing for an infinite range of possible dimensions, designers are encouraged or required to select values from a predefined Leitreihe.
This standardization offers several advantages. It reduces the number of different parts and components that need
