QIF: A Realistic Framework For The Future Of Manufacturing

Thursday, September 8th, 2016

Interoperability, collaboration, inspection, quality, standards, proprietary data, neutrality, competition, and innovation – these are words and realities that all manufacturers deal with daily. Over the years there have been myriad attempts to bring this stuff together, all while protecting IP. However, as we know, while the attempts to make this happen have often been valiant, too often they have fallen well short, or worse, failed altogether.

That failure may be on its way to being a thing of the past with the advent of the Quality Information Framework (QIF), an ANSI standard that supports digital thread concepts in engineering applications ranging from product design through manufacturing. Based on the XML standard, it contains a Library of XML Schema ensuring both data integrity and data interoperability in Model Based Enterprise (MBE) implementations.

Book Review: Re-Use Your CAD-The Model-Based CAD Handbook

Wednesday, March 5th, 2014

Over the course of a year I read a lot of books — technical, non-fiction, hardcopy, and digital. Most of them I get through, although there are some I don’t even try to finish, and a few become favorites and are kept for future reading on my bookshelf. I just finished a book entitled Re-Use Your CAD: The Model-Based Handbook by Jennifer Herron. When I saw Handbook in the title, I thought it would be just a dry reference book, but I was pleasantly surprised that it was much more than that — it’s a good learning resource.

First, a little about the author and model-based engineering/model-based design (MBE/MBD).

I’ve known Jennifer for several years as we’ve crossed paths at software conferences. She is the owner of Action Engineering, a company that specializes in the promotion, process development, and standardization of 3D CAD MBE and MBD. She is an expert in multiple CAD packages, which she uses along with her practical design experience to hone standards and processes that optimize the ROI of all CAD systems.

She also offers model-based documentation education seminars, MIL-STD-31000A schema and modeling best practice training, as well as planning consulting services for Model-Based Engineering implementation. Keep in mind as you read the book that based on her experience, she is a stickler for standards, such as ISO, but you realize that’s probably a good thing.

Her company is a consulting firm that transitions government organizations and companies to effectively and efficiently implement Model Based Engineering. With a specialty in training organizations to document and tailor their business practices to be compatible with CAD, PDM and PLM software tools, Action advises companies in: CAD modeling standards and best practice, designer modeling efficiency, CAD configuration management, MBE training, team collaboration and CAD interoperability.

The concept(s) of MBE/MBD have received a lot of attention in the past few years because this approach handles product development using a digital master model, and not just necessarily CAD. All downstream activities can be derived from the master model to develop a product. The MBE/MBD approach replaces puzzling documents and can minimize the need for physical prototypes before an optimized design has been developed. In other words, engineers and designers can simulate and iterate as much as necessary to refine a model while also meeting requirements and adhering to design constraints.

Now on to the book . . .

Reuse Your CAD Handbook

The book is structured in a logical manner for those both new and experienced with MBE/MBD. Throughout, it stresses the importance of standardizing, centralizing, documenting, and reusing a CAD database. It’s written in a CAD-agnostic manner, so its principles can be applied in any CAD environment, regardless of vendor.

A sampling of some of the topics covered in the book include:

  • Explanation of the philosophy of designing products using CAD model-based life-cycles
  • Implementation guide to model-based commercial (ASME Y14.41), government (MIL-STD-31000A) and company standards
  • Model-based benefits, risks, and action plans
  • 3D MBD model organizational schema
  • 3D MBD model protocols to satisfy the schema CAD agnostically
  • Part and assembly modeling best practice
  • Mass property implementation methods
  • 3D model Data Exchange (DEX) methods
  • MBE support infrastructure requirements
  • Product data management (PDM) fundamentals and requirements

Reusing Common CAD Parts

Friday, July 19th, 2013

A good friend of ours at MCADCafe, Jennifer Herron, owner of Action Engineering, a company that specializes in the promotion, process development and standardization of 3D CAD Model-Based Design (MBD) just released a new video on reusing CAD parts.

In the video, Action Engineering calls a catalog part, a part or subassembly used more than once in a family of products. It may be a bearing, motor, bolt or washer. In a 3D model-based environment a catalog part model should be assembled into your organization’s native CAD assembly models and includes accurate geometry (as specified from the supplier), attributes (Material, Color), metadata (Part Number, Description, Supplier) and annotations (Dimensions and GD&T). A single catalog part model is the single authority for each catalog item used in your organization.
