Mechanical Performance through Tolerance Analysis and Interface Design
We help companies that build must-not-fail products and have World Class product aspirations.
We provide software, consulting, and academy training.
We bring high performing and reliable products to market - using systematic design methods that make products less sensitive to variation. Put the other way: we make robust products by design and care about design quality; making the ultimate 3D CAD and 2D drawing foundation for high quality.
Our software is the tool of choice for tolerance calculations and interface design and help mechanical engineers solve problems and build must-not-fail products with confidence.
Through advanced CAD analytics of interfaces, assemblies, and parts, we enable higher quality, faster development, lower costs, and greener outcomes - directly from your 3D data.
Industries where Robust Design really matters
At RD8, we specialize in delivering innovative solutions tailored to diverse industries, ensuring efficiency, reliability, and performance of your products.
The more regulated, the larger the volumes and the more complex your products are - the more you will gain.
Precision by design - where safety meets certainty
Built to perform - from first prototype to final assembly
Make Lasting Results by Focusing on the Design instead of Production
Design Quality by Robust Design methods is the key to unlock new potentials.
Better Quality
Improved Delivery
Reduced Cost
- Confidence in design. Full control of cause-and-effect of design choices. Critical-to-Quality enabler.
- Taming variation. Making products Robust (insensitive to variation) by design principles.
- Predictability and lift of yield/DPMO for (critical) functions.
- Fewer tolerances and dimensions to keep in control -> leads to eased production and better supply chain.
- Reduced number of design iterations.
- Reduce time spent on maintenance tasks in engineering.
- Reduced part cost (up to 50%) by relaxed tolerances and enablement of cheaper production processes
- Reduced total cost; improved assembly, investment cost, scrap and warranty/claims cost.
- Reduced need for Quality Assurance - only where it matters.
Improved Sustainability
- Reduced CO2 footprint through design optimization (improved product efficiency,-lifetime, -material usage, less scrap, better material selection)
- Improved circular design (enabling disassembly, decoupling of materials, eased maintenance/repair)
Set the Right Design Direction from Day One and Eliminate Non-Robust Designs
Use Robust Design to identify good designs early on and prevent costly design iterations.
Eliminate and promote designs based on data-driven metrics - from the first sketch.
Mechanical Interface Design Expertise
Key Disciplines driven by Robust Design
Not all dimensions matter - but some matter a lot.
Managing variation starts with knowing which tolerances actually affect performance. RD8 maps tolerance chains across assemblies to identify critical contributors and isolate variation risks. This ensures functional reliability where it counts, while eliminating over-specification elsewhere - reducing cost, easing manufacturing, and accelerating time to market.
Your product performance is defined by its interfaces - and most problems start there.
Robust design begins by understanding how parts place, move and interact. By analyzing mechanical interfaces, constraints, and degrees of freedom early in the design process, you can uncover overconstraints and misalignments before they become a problem. The result: more precision, cleaner movement, more predictable assembly behavior, and fewer downstream surprises.
