Mastenbroek Unearths Secret
to Optimized 3D Modeling

Heavy equipment maker combines ATI FirePro graphics card with Autodesk Inventor to improve design process and support sales.

By John Marchant

Mastenbroek serves the cable and pipe-laying industries for utility, offshore, and agricultural applications around the world.  In addition to the range of standard and custom-built trenchers and plows it manufactures, the family-owned British company also supplies cable and pipe-laying systems, trench backfill machines, tracked gravel trucks, tractor-pulled gravel trailers, and a range of custom-built special machinery.

Mark Taylor, design manager at Mastenbroek for more than 30 years, puts it this way: "Currently, it's all about drainage. Our machines are helping bring previously unviable farmland into production in India, Croatia, Holland, and other nearby European countries."  He adds, "Our machines are designed for specific jobs and to do those jobs a better, more environmentally friendly way. In reality, we are selling the ability to drain this field, put that pipe in, dig this trench."

Mastenbroek’s designs are composed of thousands of parts – as many as 35,000 in some cases, and the company has always relied on Autodesk Inventor to manage the enormous assemblies. Recently, however, designers discovered that upgrading to professional graphics cards took their productivity, design quality -- and the company’s sales potential -- to a new level.

Inventor: Not Just for Productivity

Mastenbroek has been using Autodesk Inventor since revision 4 of the software. Taylor says, "Over the years, this has been of major benefit and not just on staffing levels. With Inventor, you can do a lot more with fewer people, but we don't use Inventor to shorten design times.  Instead, we invest as much time as we can to produce high-quality designs to save a huge amount of man hours in the manufacturing process. It is very rare that we build two machines the same, so the more work we can do to make the design complete before we hand it over to make, the less nonproductive workshop hours there are.

"We are always busy, and if we are not working on machines in the workshops, we are working on new designs and on prototypes,” Taylor continues. “We really are pushing Inventor very hard and have always been up there with our use of large models and complex assemblies."

Taylor says the company's largest machines comprise around 35,000 parts, and even the smallest machines will have between 6,000 and 8,000 parts, from washers to mainframe.  "We need them all there on screen so we can simulate machine operation using driven constraints -- rotating and lifting things up and down, exercising the moving parts. It is no good doing that on partial models or in wireframe."  He adds, "However, it's not just the sheer number of parts that count.  The physically larger parts in our machines can be quite complex in themselves with complex curves, etc., which means that there is more data required to describe those parts."  Read more »
   

HP's New Z Line: Breakthrough Workstation Technology

By Robert Green

Last week, HP held a joint press event with Intel to announce the new series of HP Z workstations, which are based on Intel’s new Xeon 5500 (formerly code-named Nehalem) architecture. A lot of buzz surrounded this new processor architecture but details were scarce, so I was curious to see what we’d be shown by HP and Intel executives.

The event was held in the Los Angeles area at the headquarters of BMW Group’s DesignworksUSA. The venue choice showcased the role of the BMW team in the design of the sleek new HP workstations – the studio’s projects extend far beyond vehicles – and it facilitated travel for press representatives who attended from around the world. I spoke with journalists from Asia, Europe, Australia, and South America.

New Z Workstation Family

The first order of business was announcing the new line of workstations, dubbed the Z family. Composed of the Z400 on the low end, the Z600 in the midrange, and the Z800 on the uncompromising high end, the new line offers a performance/price point for anyone who needs serious computing power. HP claims it has “reinvented the workstation,” and indeed, this new line introduces breakthroughs in system design and engineering, aesthetics, sustainability, and more.  Read more »
