Lefutás

Lefutás is a Hungarian noun formed from the verb lefutni. It is used in several contexts to describe the act of running, the progress of a process, or the time span during which something operates. The word often appears in technical and descriptive language and can take on domain-specific meanings.

In mechanical engineering and metrology, lefutás denotes runout, the deviation of a rotating component from a perfect circular path. It is typically discussed as radial and axial runout and serves as a quality and tolerance indicator. Excessive lefutás can indicate misalignment, bearing wear, or mounting inaccuracies, and corrective actions may include rework, rebalancing, or proper alignment.

In computing and information technology, lefutás refers to the runtime or execution of a program or script. It describes the period during which software runs and performs its tasks. The term is common in technical documentation and performance discussions, for example: “A program lefutási ideje 2 perc.”

More generally, lefutás can mean the course or unfolding of a process over time. For example, “a projekt lefutása” describes how the project progresses from start to finish.

Etymologically, lefutás comes from the verb futni (to run) with a prefix that conveys completion or progression, yielding a sense of something that runs its course. The term is primarily used in Hungarian technical and formal language.
