Obrabiane

Obrabiane is a Polish term used in engineering and manufacturing to describe a workpiece that has undergone machining. It refers to material removal or shaping by cutting tools to reach the required geometry and surface finish. The word characterizes parts that originate from raw materials such as bars, billets, forgings, or castings and have been subjected to subtractive processes.

Machining encompasses a range of operations, including turning (toczenie), milling (frezowanie), drilling (wiercenie), boring, grinding (szlifowanie), and finishing operations like deburring. Modern production frequently uses computer numerical control (CNC) equipment to perform these tasks with high precision and repeatability. The term obrabiane often appears in plans and drawings to distinguish machined features from those that are formed by casting, forging, or other methods.

Documentation and quality control are closely linked to the concept. Technical drawings may indicate which surfaces or features must be machined, specify tolerances and surface roughness, and require inspection using instruments such as micrometers or coordinate measuring machines (CMM). Achieving the specified tolerances and finishes is a key aspect of validating that a part is properly obrobione.

Etymology and usage notes: obrabiane derives from the verb obrabiać (to machine or to process). It is commonly used in industry and education to contrast machined components with untreated or differently treated ones. Related terms include obróbka skrawaniem (machining), toczenie, frezowanie, and szlifowanie.
