AutoForm Assembly R26 (Smart Pattern-Making & 3D BiW Design)

Overview of AutoForm Assembly R26

AutoForm Assembly R26 is part of the AutoForm BiW software product line, which supports the entire BiW assembly process chain from early feasibility through process engineering to production. The software enables users to simulate assembly processes, evaluate alternative part and assembly designs, identify root causes of dimensional deviations, and implement effective countermeasures before physical production.

The software is built around several core modules:

• AutoForm-Explorer: For simulation setup and result evaluation, including forming, hemming, and joining processes.

• AutoForm-HemPlanner: For efficient planning and optimization of hemming processes, supporting both roller hemming and table-top hemming.

• AutoForm-FormFit: For modifying single-part geometries to meet dimensional accuracy requirements in the assembly state.

• AutoForm-LineWelding: For analyzing how thermal effects from line welding influence dimensional accuracy.

• AutoForm-BuildOptimizer: For selecting optimal joining fixture parameters in assembly production.

• AutoForm-AssemblySolver: The core solver that simulates BiW assembly processes, calculating results rapidly for both early development and final validation.

The software integrates closely with AutoForm Forming, allowing springback and stress data from stamping simulations to be carried directly into assembly analysis. This integration creates a continuous digital process chain from sheet metal forming through to final assembly validation.

Key Features of AutoForm Assembly R26

AutoForm Assembly R26 offers a comprehensive set of features designed to improve assembly process validation and dimensional accuracy.

MIG/MAG Arc Welding Simulation

The most significant new feature in R26 is the arc welding model for MIG/MAG welding processes. Unlike laser welding, MIG/MAG welding generates higher heat input, resulting in a larger heat-affected zone and increased thermal distortion. The software automatically determines effective heat input and resulting thermal loads using key process parameters, enabling realistic prediction of welding-induced dimensional deviations.

GD&T Integration

GD&T (Geometric Dimensioning and Tolerancing) information from CAD becomes an integral part of the simulation workflow in R26. GD&T definitions are automatically interpreted and used throughout setup and evaluation, preserving the original design intent from CAD. This creates a direct link between engineering requirements, assembly validation, and quality assessment.

Scanned Subassembly Data Integration

The software now supports efficient use of scanned subassembly data. Measured subassembly geometry can be directly integrated into the simulation, enabling more realistic and reliable results. This is particularly useful when prototypes become available in later development stages.

Mirroring and Translation of Assembly Files

New options for mirroring and translation of asm files accelerate simulation setup and increase engineering efficiency. Users can also efficiently reuse and adapt existing subassemblies for new vehicle projects, with the software automatically updating subassembly definitions.

Compensation Strategy Development

AutoForm Assembly R26 enables users to analyze deviations from nominal caused by the assembly process and determine which parts most influence dimensional accuracy. New target geometries for single parts can be derived to achieve the final dimensional fit of the assembly.

Hemming Process Simulation

The software supports both conventional die hemming and robotic roller hemming, with capabilities for generating roller tools and their trajectories, defining active faces of pre- and final hemming tools, and evaluating tool forces, material roll-in, geometry of the hem, material wrinkles, and splits.

What’s New in AutoForm Assembly R26

AutoForm Assembly R26 introduces several important enhancements over previous versions.

New Arc Welding Model

The new arc welding model for MIG/MAG simulation represents the most significant addition. It automatically calculates effective heat input based on key process parameters, providing deeper insights into welding effects on dimensional behavior and supporting optimized joining process design.

Enhanced GD&T Workflow

GD&T information from CAD is now automatically interpreted and used throughout the setup and evaluation process. This establishes a direct link between engineering requirements, assembly validation, and quality assessment, enabling faster and more consistent validation.

Scanned Subassembly Support

The ability to directly integrate measured subassembly data into simulations enables more realistic and reliable results, particularly when prototypes become available during development.

Improved File Handling

New mirroring and translation options for asm files accelerate simulation setup. The software also enables efficient reuse and adaptation of existing subassemblies for new vehicle projects, automatically updating subassembly definitions.
