Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 113: Integrated application resource: Mechanical features. This part of ISO 10303 (STEP) defines integrated resource constructs and information structures used to represent mechanical and machining-related features in product and manufacturing information (PMI).

Abstract

ISO 10303-113:2020 specifies integrated resource constructs for mechanical features, including constraints on identifiers for topological items, descriptions for counterbore/countersink/counterdrill/spotface, machining features for milling and turning, pattern replication of features, generic mechanical design concepts, implicit representations using standard parameters, machining feature definition elements, PMI placeholders in 3D models and shape representations required for creating machining features.

Scope

This part provides the integrated application resource constructs needed to represent mechanical (machining and design) features within the ISO 10303 framework. It covers the definition and application of feature types used in manufacturing contexts (milling, turning and replicated patterns), rules for lifecycle-context identifiers for topology, placeholders for product and manufacturing information in 3D models, and the shape representations required to form machining features. The standard is intended to be used where a consistent, implementation-independent representation of mechanical features is required for data exchange and downstream manufacturing processes.

Key topics and requirements

• Formal integrated resource constructs for mechanical and machining features (feature definitions and relationships).
• Rules and constraints for lifecycle-context invariant identifiers for topological items used in feature representation.
• Definitions and parameters for counterbore, countersink, counterdrill and spotface features.
• Support for features manufactured by milling or turning processes and for feature patterns (replication).
• Implicit feature representation via standard parameter selection and the elements necessary to define machining features.
• Placeholders for product and manufacturing information (PMI) in three-dimensional geometric models.

Typical use and users

ISO 10303-113:2020 is typically used by CAD/CAM/CAE software developers, PLM and PDM system integrators, manufacturing engineering teams (process and NC programmers), standards implementers, and organizations needing neutral, long-term exchange of feature-level product and manufacturing information. It supports interoperability between design systems and downstream manufacturing systems by providing a standardized feature representation usable in data exchange and automation workflows.

Related standards

ISO 10303-113 is part of the wider ISO 10303 (STEP) family. Related and relevant parts include the earlier application interpreted construct ISO 10303-522 (Machining features), which was superseded in this area, and other core STEP parts such as ISO 10303-1 (overview and principles) and various Application Protocols (APs) that address exchanged CAD/CAM/PMI data (for example AP238 / AP242 in related domains). Implementers working with mechanical features commonly reference ISO 10303-522 (historical) and later revisions of Part 113.

FAQ

Q: What is this standard?

A: ISO 10303-113:2020 is Part 113 of the ISO 10303 family (STEP). It defines integrated application resource constructs for mechanical and machining-related features used in product and manufacturing information exchange.

Q: What does it cover?

A: It covers feature definitions and constructs for counterbore/countersink/counterdrill/spotface, features made by milling or turning, pattern replication of features, constraints for lifecycle-context identifiers for topology, implicit parameter-based feature representation, and PMI placeholders in 3D models—together supporting accurate exchange of machining and mechanical feature information.

Q: Who typically uses it?

A: CAD/CAM/CAE vendors, PLM/PDM implementers, manufacturing engineers, NC programmers, and standards/interop engineers who require consistent, neutral representations of mechanical features for data exchange and downstream manufacturing.

Q: Is it current or superseded?

A: The 2020 edition (Edition 1) was published in October 2020; lifecycle records indicate it has subsequently been revised within the series and references show later editions/revisions (for example ISO 10303-113:2022). Users should check the ISO catalogue or their national standards body for the most current edition before purchase or implementation.

Q: Is it part of a series?

A: Yes — it is one part of the ISO 10303 (STEP) series of standards for product data representation and exchange. The series includes foundational parts (such as Part 1 and Part 11), application protocols (APs) and numerous integrated resources that together enable comprehensive product model exchange.

Q: What are the key keywords?

A: STEP, ISO 10303, mechanical features, machining features, AP113, PMI, CAD/CAM, integrated resource, feature representation.
