Siemens Meet at the Machine: Be productive from day one of new CNC machine delivery

Traditionally, many programming, validation, and training activities begin only after a machine is installed. Not anymore. Meet at the Machine is Siemens' new initiative uniting machine builders, software, and automation for next-level CNC through a continuous digital thread across engineering, programming, virtual validation, and execution. By pairing a Digital Twin with Digital CNC powered by SINUMERIK, manufacturers can prepare, validate, train, and optimize workflows before your specialized machine's physical delivery! TRAK Machine Tools is the launch partner -- see what they are doing.

Custom 3D-printed steering wheel for jet dragster

Jet dragsters use General Electric J85 engines -- the same turbines pulled from U.S. military F5 Freedom Fighters -- mounted to a custom 26-ft chassis. The racers achieve quarter-miles in 5.5 sec, but standard metal parts can fail custom ergonomic needs. Traditional manufacturing of low-volume aluminum steering wheels demands long, 8-day lead times, high costs, and multi-piece assemblies. Larsen Motorsports solved this by replacing metal with continuous fiber 3D printing using the Markforged X7. Embedding continuous carbon fiber into an Onyx nylon matrix allowed them to target specific load paths, delivering a custom steering wheel that is stiffer, lighter, and faster to produce than aluminum.

Cummins-Peterbilt SuperTruck gets Modine waste heat recovery heat exchangers

Modine Manufacturing Company, a world leader in thermal innovation, is developing a series of compact heat exchangers designed to capture waste heat from the exhaust stream of a diesel engine and convert this heat into useful power to improve engine efficiency and reduce CO2 emissions.

As part of this development effort, Modine has been involved in a Department of Energy-sponsored program called SuperTruck and has provided these heat exchangers to a Cummins-Peterbilt concept vehicle for comprehensive road testing. During this road testing, the vehicle achieved 10.7 mpg. The truck also demonstrated a 75 percent increase in fuel economy in head-to-head testing over a 24-hr time period compared with a 2009 baseline truck. These results translated to a 43 percent reduction in greenhouse gas emissions and an 86 percent gain in freight efficiency. The vehicle was on display at a recent event in Maryland where President Obama announced that work would begin on the next phase of national greenhouse gas and fuel efficiency requirements for commercial trucks.

The Department of Energy (DOE) initiated the multi-year SuperTruck program in 2010 with the goal of designing a heavy-duty Class 8 truck that achieves a 50 percent improvement in overall freight efficiency. That increase in fuel economy would save about $25,000 annually based on today's diesel fuel prices for a long-haul truck traveling 120,000 miles per year. The DOE set the goal of attaining part of the overall efficiency gains from engine improvements, with the remaining gains coming from other vehicle improvements such as aerodynamics, use of lighter-weight materials, and reduction of friction in the drive train. Class 8 trucks represent only about 4 percent of the on-road vehicles in the United States but are responsible for almost 20 percent of the country's on-road fuel consumption.

The Cummins-Peterbilt collaboration was one of several DOE-selected partner projects. The objectives of this partnership were to develop and demonstrate a highly efficient and clean diesel engine, an advanced Rankine-based waste heat recovery system, an aerodynamic Peterbilt tractor-trailer combination, and an auxiliary power unit (APU) to reduce engine idling. Cummins and Peterbilt selected Modine to provide the heat exchangers for the waste heat recovery system.

The Rankine-based waste heat recovery system operates similarly to a conventional stationary power plant. A power fluid is boiled using the heat from the diesel engine exhaust and is sent to a turbine, which converts this heat into mechanical energy. By recovering this energy from the exhaust, the diesel engine uses less fuel and CO2 emissions are reduced. Multiple heat exchangers are required for this system to operate efficiently.

However, unlike a conventional power plant, these heat exchangers must be miniaturized to fit under the hood and on the chassis of a conventional Class 8 truck. "Our research engineers utilized Modine's technology building blocks to develop highly compact heat exchangers to meet the thermal management and space requirements of this new challenge," says Lawrence Gabbey, Modine Research Engineering Section Manager and Program Manager for the SuperTruck program. "Leveraging the success of this demonstration program, Modine continues to develop this waste heat recovery technology in preparation for future commercial opportunities around the globe in the commercial vehicle and automotive markets."

The Modine SuperTruck front-end cooling module consists of a radiator, charge-air cooler, air-conditioning condenser, and new waste heat recovery condenser. Lower left (in front of the module): stainless steel EGR Boiler-Superheater for the engine. Lower right: aluminum Recuperator. Both additional heat exchangers are part of the waste heat recovery system. This photo depicts six Modine heat exchangers in all. Modine also provides a tailpipe boiler.

 

 

 

 

"Fuel economy and the reduction of CO2 emissions are two strong technology drivers that will create many opportunities for Modine heat exchanger technology in the future," says Jonathan Wattelet, Modine's Global Director of Research and Technical Services. "The SuperTruck public-private partnership sponsored by the Department of Energy has been an excellent opportunity to leverage our research in areas where longer-term research is too risky to undertake alone. Working with engine and commercial vehicle leaders such as Cummins and Peterbilt has been an outstanding opportunity for Modine to obtain much-needed engine test cell and road testing experience for our newly developed heat exchanger technology."
