Application

Design takeaway

Shift from 2D drawings and separate data files to a unified 3D Model-Based Definition (MBD) approach that embeds all necessary manufacturing and quality information within the CAD model.

How to apply

When developing new products or revising existing ones, ensure that the CAD models include all necessary tolerances, surface finishes, and inspection requirements as embedded PMI. Advocate for the adoption of MBD standards within your organization.

Project actions

01When creating 3D models for a design project, consider adding annotations for manufacturing or assembly directly within the model.
02Research the capabilities of your chosen CAD software to embed Product Manufacturing Information (PMI).

Method & Evidence

AimTo investigate the feasibility and value of using STEP AP242 models with embedded PMI for CAD-to-CAM and CAD-to-CMM data exchange to improve process efficiency.

MethodGap analysis and feasibility study

ProcedureThe research analyzed existing tools, standards, and processes to identify barriers to effective model-based data interoperability. It explored the potential of using STEP AP242 models containing both geometric data and PMI for downstream manufacturing and inspection tasks.

ContextProduct design and manufacturing supply chains, particularly in original equipment manufacturing (OEM) environments.

Variables

IVUse of 3D models with embedded PMI vs. traditional 2D drawings and separate data.

DVProcess efficiency, data interoperability, error reduction.

CVType of product, complexity of design, specific manufacturing processes.

Strengths & Limitations

Strengths

+Addresses a critical need for digital integration in manufacturing.
+Highlights the potential of emerging standards like STEP AP242.

Limitations

The study focused on identifying gaps rather than providing solutions for every identified issue, meaning practical implementation might still require significant effort.

Reliability & validity

The validity of the findings relies on the expert analysis of existing tools and standards. Reliability would be enhanced by empirical testing of data transfer between specific software packages.

Think critically

To what extent do current industry adoption rates of MBD reflect the technical feasibility highlighted in this research, and what are the primary socio-technical barriers to wider implementation?

Design Principles

"Embed all relevant product definition data, including manufacturing and quality specifications, directly within the primary 3D model to ensure a single source of truth and enhance downstream process efficiency."

This approach reduces reliance on traditional 2D drawings and separate data files, leading to fewer errors, faster production cycles, and enhanced product quality. It's a foundational step towards a fully digital and integrated manufacturing enterprise.

What This Means for Your Design

Using 3D computer models that contain all the instructions for making and checking a part, instead of separate 2D drawings and documents, makes the whole process faster and less prone to mistakes.
