Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 240: Application protocol: Process plans for machined products (ISO 10303-240:2005). This part of the ISO 10303 (STEP) family defines the information model and integrated resources needed to exchange, share and retain computer-interpretable process plan information for both numerical control (NC) and manually operated machining applications, together with associated product definition data.

Abstract

ISO 10303-240:2005 specifies the use of integrated resources to meet the information requirements of process plans for machined parts. It covers process data for routing and operations (NC and manual), interfaces to upstream product-definition data (including material and design-exception tracking), machining features and feature classification, geometric and dimensional tolerances, materials and properties, references to standards, work instructions, resource references and sequencing, NC programming support, shop-floor information and production-planning information.

Scope

Defines an application protocol for the exchange, archival and sharing of computer-interpretable process plans for machined products. The scope includes capturing process-planning output for single-piece mechanical parts and assemblies for manufacturing purposes, representing machining features and classifications, tolerances, materials and references, providing work-instruction sequencing and resource references, and supporting downstream NC programming and shop-floor / production planning information exchange.

Key topics and requirements

• Information model for process plans covering NC and manual operations.
• Representation of machining features and a feature-classification structure.
• Inclusion of geometric and dimensional tolerances, material definitions and part properties.
• Work instruction sequencing, resource references and shop-floor/production-planning data.
• Interfaces to upstream product-definition resources (design exception tracking, initial material definition).
• Support for data exchange, long-term retention and interoperability between CAPP/CAM/CNC systems.

The above topics are drawn from the standard’s stated information requirements and scope.

Typical use and users

Used by manufacturing enterprises, CAM/CNC programmers, computer-aided process planning (CAPP) software vendors, PLM and MES integrators, and system implementers who require a neutral, vendor-independent representation of machining process plans for exchange, archival and integration with design and production systems. It is commonly adopted where interoperability between CAD/CAM/CAPP and shop-floor systems is required.

FAQ

Q: What is this standard?

A: ISO 10303-240:2005 is an application protocol (AP 240) within the ISO 10303 (STEP) family that specifies a data model for process plans for machined products to enable exchange, sharing and archival of process-plan information.

Q: What does it cover?

A: It covers computer-interpretable process plans for both numerical-control (NC) and manual operations, including routing and operation data, machining-feature representation and classification, tolerances, material and property definitions, references to standards, work instructions and sequencing, and information to support NC programming and shop-floor/production planning.

Q: Who typically uses it?

A: Manufacturers, CAM/CNC programmers, CAPP system vendors, PLM/MES integrators and implementers seeking neutral data exchange for machining process plans. Researchers and tool vendors validating conformance to STEP application protocols also use it.

Q: Is it current or superseded?

A: ISO 10303-240:2005 remains a published International Standard; the ISO entry indicates the publication was reviewed and confirmed (most recently confirmed in 2024), so this edition is current (not withdrawn or superseded as of the latest ISO confirmation).

Q: Is it part of a series?

A: Yes — it is part of the ISO 10303 series (STEP). The series groups descriptive methods, integrated resources and application protocols; AP 240 is one of many application protocols in the family addressing specific product-data exchange use cases.

Q: What are the key keywords?

A: Process plan, machining, AP240, STEP, CAPP, CAM, NC, feature classification, work instructions, product data exchange.
