Työkappaleiden

Työkappaleiden is the genitive plural form of työkappale, a Finnish term used in engineering, manufacturing, and workshop contexts. A työkappale is a piece of material that is intended for processing, testing, or evaluation. The form työkappaleiden is used when describing things related to multiple workpieces, such as their dimensions, processing, or quality.

In practice, työkappaleiden appears in technical texts to denote attributes or actions concerning more than one workpiece. Examples include työkappaleiden mitat (the dimensions of the workpieces), työkappaleiden käsittely (the handling of the workpieces), and työkappaleiden valmistus (the production of the workpieces). The term is common in machining instructions, quality control documentation, prototyping, and product development workflows, where references to sets or batches of parts are routine.

The word also covers both test pieces and production parts, depending on the context. In educational or training settings, työkappaleiden may refer to a set of sample pieces used to demonstrate processes or measurement techniques. While työkappaleet is the plain plural subject form, työkappaleiden serves to express relations such as ownership, association, or characteristics of multiple workpieces within a sentence.
