This must be the week for good news about education. Besides my always uplifting experience speaking with Dartmouth graduate students, I heard today that the Manchester (NH) School of Technology will be featured on CNN’s Anderson Cooper 360 on Thursday, April 15, 2010 at 11:30 PM. According to MST principal Karen White, ” It is about how the state of NH has done better than other states in the country on dropout prevention and we were chosen by the Dept of Ed to showcase our efforts. One of the highlights is that technical education is what is attracting students and keeping them in”.

I’ve been working with MST as part of a advisory group that has helped them institute a manufacturing technology program for their students. This is a comprehensive program that provides hands-on education in all aspects of technologies involved in manufacturing.  The program features a well equipped training area and an experienced teacher focused on this curriculum. Part of the training includes introductions to lean manufacturing, statistical techniques, and the many people skills required for a successful career. Students come out of the program ready to go to work, or to enter a more in-depth continuation of the training at Manchester Community College. Either way, manufacturers are getting new workers ready for successful careers in industry.

Dartmouth Engineering Graduate Students are Getting Ready for the Real World

I just finished my fourth yearly visit to Dartmouth College to speak to their Master of Engineering Management students about running a manufacturing company. These students are in a great program that prepares them for real world situations. All students go through certification for Six Sigma Black Belt and are well versed in principles of Lean Manufacturing and Theory of Constraints. We had the pleasure of working with two of their students on research projects here at Graphicast. They helped us solve a recurring quality issue in casting and developed a method for reducing set up times in CNC machining. I always enjoy my time at Dartmouth and hope we can work with their students on other projects in the future.

Graphicast Featured in Automation World

Graphicast’s lean manufacturing journey is highlighted in this article from the July 2009 edition of “Automation World“.

Acres of Seats

November 19, 2009

I had the pleasure earlier this week of visiting one of our key customers, Weber Aircraft, in Gainesville, Texas. Weber is the preminent supplier of airline seats to the major airframe manufacturers and airlines. Although we take an airline seat for granted, beneath the fabric is a sophisticated structural engineering masterpiece  (even the fabric is a highly engineered structure!). The seats meet rigorous safety standards and are custom engineered to each airline’s specifications and features.  We make the seat escutcheon, the curved plate at the end of the armrest that your fingers grab if you’re a white knuckle flier. We were able to see hundreds of seats in various stages of production during our plant tour. Weber has a well established lean manufacturing culture and is a strong believer in continuous improvement. We are pleased to be part of their success.

From the CEO

October 23, 2009

Next week, October 26 – 28, I’ll be at Synergy Resources’ User Conference in Providence to talk about our success with the shop floor scheduling system we use. For those who have read “The Goal“, Eli Goldratt’s business novel about a factory that increases throughput and cuts inventory, you would recognize our schedule. The whole system is based on Goldratt’s Theory of Constraints. Consistent with lean principles, Theory of Constraints looks to continually identify areas of your operation that “constrain” your output , so you can focus efforts on relieving that constraint to free up capacity. Our constraint was procedural, as opposed to a piece of equipment slowing us down. Once we applied the new scheduling concept, our lead times dropped by 75%, freeing up a lot of capacity for growth and making us much more responsive to your needs. We’re already seeing a lot of rush orders, and are ready for the recovery. We hope to see you with us as we move back into the light of economic growth.

Design and Rapid Prototyping Service

Now Offering Design and Rapid Prototyping Service for Castings

The timeline shows why customers use Graphicast’s Design and Rapid Prototype Service (DRPS). You can greatly shorten time to market and reduce development costs at the same time. Graphicast will help engineer your part as a casting from the start, giving you the opportunity to maximize as-cast features in your part. This reduces machining, saving you money on production parts.

Graphicast has worked with customers for more than 30 years to turn their part designs into cost effective casting solutions. Graphicast often works within an existing design, a fabrication, a machined part, or a machined prototype component. Since the parts were not designed as a casting in these examples, there may have been lost opportunities to gain the full economic benefit of as-cast features. What if the design process started with the thought of casting the part?

By starting a new part design with the casting process in mind, all considerations of a casting (draft, radii, cast surfaces, and near net shape geometry) can be incorporated to take full advantage of the process. This yields the lowest part cost. This is why Graphicast offers a Design and Rapid Prototype Service. Graphicast will work with you from the beginning of your product design process to develop the most cost effective casting solution for your part. Additionally, Graphicast can greatly reduce total development time and cost by eliminating intermediate prototyping steps. You will be prototyping to the final design in the final material.

Graphicast’s Design and Rapid Prototyping Process

In talking with our customers, we learned they often go through two steps in their current product development process. They first employ several rapid prototyping methods (most frequently stereolithography – SLA) during concept and early design stages, and then go on to produce a CNC machined prototype at the end of the process. Most indicated it would have been a huge benefit to have had help with casting design at the start of the project. They saw the benefit as not just time and cost savings, but also viewed it as a tool to reduce stress on their internal resources.

The key to successfully applying a casting process to a new product design is to consider the process capabilities and limitations right from the start of the project, when there is maximum design flexibility. This is a goal of any Lean Product Development or Design for Manufacturability effort. By using Graphicast’s expertise in converting parts to castings, we want to help you plan the most cost effective approach to your original design. Typically, when the design meets your criteria and approval, we produce a SLA prototype. We find this gives our customers a very clear idea of what the final part will look like and to use it for form, fit, and function checks.

Frequently, this stage provides the knowledge and confidence to proceed directly to production of the mold. In the case where a metal prototype is required to test specific properties (such as thermal or electrical conductivity, strength, EMI shielding, or lubricity), or for an assembly fit or mechanical testing, we can produce a CNC machined prototype made from our ZA12 alloy. The ZA12 prototype can incorporate all the design considerations of a casting. In all cases, the time to produce the mold and cast the first production parts is greatly reduced because the part design was done in the prototyping stage.

Graphicast believes this process is so effective, we will apply $1000 of any DRPS project toward the cost of the graphite mold for the part designed in the project.

The photograph shows the full extent of a DRPS project. Starting from the lower left and proceeding clockwise: SLA prototype part, CNC machined prototype part, machined production casting, plated production part. The entire design process can be explored in a variety of prototyping methods to achieve the best design for your part.
