montageposities

Montageposities are predefined spatial configurations used during the assembly or installation of components within a system. The term is used in Dutch engineering, manufacturing, and construction to refer to the specific positions and orientations in which parts must be mounted, aligned, and fastened.

In practice, montageposities are defined in engineering drawings and assembly instructions through coordinate frames, datum references, and hole or fastener patterns. They specify where a component is located relative to reference features, the orientation of faces or axes, and the sequence of mounting steps. They enable consistent assembly, repeatability across workstations, and compatibility with other parts.

Design and planning: Engineers determine montageposities by considering functional requirements, accessibility for assembly tools, clearance for other parts, thermal expansion, and serviceability. Tolerances are specified to control positional accuracy. Fixturing and jigs are often used to hold parts in the correct montagepositie during assembly.

Quality and measurement: During production, checks compare actual positions to nominal montageposities using measurement techniques such as coordinate measuring machines, optical gauging, or go/no-go gauges. Deviations may indicate process issues or part variation.

Examples: In automotive assembly, mounting positions for an engine to the chassis; in electronics, the position of a circuit board within a housing; in HVAC, the orientation of duct connections.

Relation to related terms: Montage describes the act of assembling; montageposities are the defined targets for where and how parts join. They are distinct from but closely linked to tolerances, fixtures, and assembly sequencing. See also fixturing, GD&T, assembly drawing, datum, bolt pattern.
