  • AccumoldAccumolds primary focus is on

    manufacturing micro-sized plastic parts

    and components for industries that

    require fast turn around and complex

    parts, such as micro-electronics,

    micro-optical and medical. The original

    Micro-Molder was designed to help

    manufacture parts with minimal waste

    and short cycle times for electronic

    component manufacturing. These minute

    parts are often measured in microns,

    are no bigger than 0.5 in.3 and typically

    weigh less than 1 g. In addition to their

    size, these parts have tight tolerances and

    must be molded efficiently and precisely.

    Incorporating small features on a normal-

    sized part (up to about 3 in. in diameter) is

    another of the companys capabilities.

    1 6 DESIGN WORLD December 2015

    College has changed a lot since I was a student. Shortly after I graduated from Georgia Tech, the campus underwent quite the building boom, thanks to its upcoming status as the Olympic Village for the 1996 Summer Olympic Games. Touring the school in the subsequent years always left me amazed at the new amenities. And I can recall looking at the University of Arizona when I was considering graduate school, my jaw dropped at the prospect of high-rise dorms with huge swimming pools right beside them. It was like spring break compared to what Id known. But changes in the college experience today go far beyond mere physical structures. While touring the new Sears Think[box] innovation hub on the campus of Case Western Reserve University, I was blown away ... what these engineering students have at their disposal today is incredible. Think[box] functions as a comprehensive fabrication laboratory, a place where the University hopes members of the engineering, design, arts, humanities, science, medical and business communities will interact. The goal is to help both students and faculty become the entrepreneurs and technology leaders of the future. Think[box] is also open (and free!) to the public, which I think will add a great mix to this campus hub. Think[box] has been around since 2012, but its just moved into a new $35M home, a seven-story, 50,000 sq-ft building. The layout of the project is quite impressive: The fir t floor includes interactive presentation and workshop areas, an inventors hall of fame and social meeting spaces focused on users from outside the university, including K-12 students, industry groups and community groups. The second floor has open space to support generation and development of ideas. There is a range of informal, re-configurable spaces for users to meet, think and develop their ideas. It will include multi-media equipment to support group collaboration and expression. The third floor focuses on prototyping, with a wide range of state-of-the-art digital manufacturing equipment for users to quickly turn their ideas into some form of physical object. The fourth floor houses traditional fabrication/manufacturing workshops. The next phase of the project, to happen over the next year, will add a garage-style project floor; a floor devoted to startup assistance (including business planning, intellectual property and legal advice), and a floor for incubating startup companies that develop both within and outside the university. Ive been told that top-notch universities have been visiting Think[box], to see how to create similar spaces on their campuses. My thought was: What a great recruiting tool for CWRU. I tried to imagine prospective engineering and design students getting a campus tour and then seeing this lineup of toys: 3D printers, circuit-board routers, laser cutters, a computer-controlled ShopBot router, a Lynx 3D Microscope, a 3D scanner, a mixed signal oscilloscope and a vacuum chamber. What aspiring engineer wouldnt want to playand learnhere? DW

  • Te s c h l e r o n To p i c

    Theres a lot of public lamentations that too few youngsters see engineering as a

    profession worth pursuing. Ive

    come to think part of the problem

    is with experts trying to describe

    what engineers really do, giving

    explanations that are murky and

    unsatisfying. So kids have trouble

    distinguishing the activities of

    engineers from those of car mechanics

    or maintenance personnel.

    One who has taken a stab at explaining what engineers do is Guru Madhavan, a biomedical engineer. He wrote a book called Applied MindsHow engineers think, in which he claims engineers visualize the structure of a problem by breaking it down into elements linked by logic, time, sequence and function. Madhavan also says engineers work under constraints, make tradeoffs o get reasonable solutions and divide complicated problems into manageable pieces.

    What do engineers really do? And do computer programmers really do it?

    1 8 DESIGN WORLD December 2015

    This description sounds reasonableuntil you consider that real estate developers, scrap yard managers and movie producers might all claim to go through similar sorts of processes to get a job done. Alternatively, some might say Albert Rothenberg gets closer to the essence of engineering in another book called Flight from Wonder: An Investigation of Scientific Creativity. Rothenberg is a psychiatrist who does research on creative thinking processes. He said the creative thinking techniques he describes in his book come from Nobel laureate scientists, not engineers. Nevertheless, engineers reading the book are likely to recognize cognitive tricks they use themselves. For example, a visual imagery exercise called homospatial reasoning involves overlaying and combining ideas in different ways. With another technique called the sep-con method, you conjoin functionally separate ideas or objects in odd ways to see what happens. Rothenberg also takes a crack at describing broader qualities that Nobel laureates possess. They include passion, self-confidence, openness, courage and domain expertise. Many of us would probably say weve often seen colleagues display those qualities and thinking processes. Trouble is, passion, self-confidence and an ability to combine ideas in novel ways arent exclusively found in either engineers or Nobel laureates. Its not out of line to say farmers, fire ghters and construction workers can display the same qualities. The inability to defi e what engineers really do has lead to a disagreement about who an engineer really is. That brings us to video game

    designer Ian Bogost. Writing in The Atlantic, he recently suggested that software experts are programmers, not engineers. The title engineer is cheapened by the tech industry, he writes. Bogost asserts that an engineer is someone who is regulated, certified and subject to continuing education requirements. He or she has to jump through these hoops because something could go terribly, horribly wrong with unqualified actors at the helm When it comes to skyscrapers and bridges and power plants and elevators and the like, engineering has been, and will continue to be, managed partly by professional standards, and partly by regulation around the expertise and duties of engineers. But 50 years worth of attempts to turn software development into a legitimate engineering practice have failed, he said. Bogost argues that, in contrast to maintaining professional standards, there is an informality to software work that is being made worse by movements such as agile development, which focuses on rapid iterations rather than long-term planning. This sort of slap-dash fi -it-later thinking is the antithesis of engineering. Bogost didnt set out to explain what engineers do, but he helps show what separates engineering from areas where a cobbled-together solution is acceptable. Simply put, engineers are people who have a responsibility to produce a product that is safe and reliable. Their expertise as builders and designers originates from that responsibility. DW

    3D printing stocks have been tanking

    for several months. 3D Systems CEO Avi

    Reichental stepped down. Everyone is

    waiting for HP to introduce its super-fast

    new 3D printer next yearand blow

    established 3D printing vendors out of the

    water. According to stock analysts, this

    is practically a fait accompli because HP

    has more money than the other players,

    and obviously money trumps all other

    capabilities. If HP doesnt introduce a new

    3D printer, it can just buy Stratasys or

    3D Systems, say the stock analysts, and

    achieve market dominance that way.

    Then we have the news that traditional printer companies Canon and Ricoh have decided to enter the 3D printing market. Investors are showing a disappointing lack of knowledge about 3D printing/additive manufacturing (3DP/AM). And this ignorance is harming those involved in this industry. Investors should have done due diligence; their actions (selling off tocks, short selling the market, fili g lawsuits) indicate they did not. A 3D printer in every home? Eventually. Just not this year. Probably not next year either. Will 3DP/AM revolutionize manufacturing? Not likely. Ever. 3DP/AM is not a replacement for traditional manufacturing. Its simply another tool for traditional manufacturing to usewhen it

    makes sense. When you can stamp out thousands of parts for fractions of

    a penny, why would you install a slower, more expensive process to

    accomplish that? Could 3DP/AM get as fast or faster than traditional manufacturing? Maybe. But it will take years. Meanwhile, traditional manufacturing technology is not standing

    still. 3DP/AM is a long-term

    buyprobably 10 years. Why? Education. Whats needed now is

    the ability to design to 3DPs advantages. Just wait until todays students, who are exploring 3DP now, graduate. Stock investors will see a different market then. And they may wish they had stayed in this market early. Several companies in this industry have the potential to be the next Apple. This industry is just beginning to fi d its legs. Developers have known what problems it solves for some time. But the message is still getting out. As of today, and tomorrow, the best problems that 3DP solves are those that involve creating custom, one-offproducts and developing parts impossible to make other ways. Just consider the weight reduced Airbus bracketsthere is no way to machine these parts. The industries that can best take advantage of these capabilities are where 3DP is working best today, like medical, including dental and prosthetics, and aerospace. Rather than short sell companies in this market, smart investors will see that they can get in on the ground floor of this industry now. DW

    JOHANNES TEIGELKTTERHBM

    Why you should consider air bearings

    Johannes has worked in the industry for 14 years, from 1986 until 2000. He worked in fields ranging from power electronics and instrumentation to drive technology for locomotives. But recently, he has been teaching and researching as a professor in the fields of electrical machines, power electronics and drives at the University of Applied Sciences in Ascheffenburg. Sometimes young engineers only rely on outputs of a computer calculation without verifying, he said. I think its very important to learn how to check these results on the basis of physical phenomenon. The best thing about his job, he said, is working with students to find a creative solution for technical problems. A few years ago, I developed an electric powered kart with my students. We carried out several test runs to optimize the system, he said. During one test run, the right rear wheel broke and the kart was overtaken by the wheel. Luckily, the kart was able to run on three wheels and could be brought to a halt without any accidents. And while he works with the future of engineering, he still doesnt see a predictable future. To quote Niels Bohr, Prediction is very difficult, especially if its about the future he said. The world is changing very fast so its impossible to predict whats going to happen in 20 years.

    fun factJohannes enjoys both the Harry Potter novels and movies. He especially likes watching the movies and reading the novels with his children.

    Matt earned his bachelors degree in Mechanical Engineering from the University of Pittsburgh. While in school, he participated in a co-op program where he spent 16 months working as a junior engineer for a Fortune100 company full time. (Students should) take every chance to engage in internships and co-op programs, he said. After his time in the co-op program, Matt said knew so much more about how things get done in the industry than he would have without that experience. The work experience also helped guide my class selection in my last year of school, as I became more interested in certain topics. But, he also wishes he had learned more about the manufacturing processes during his time as a student. I think schools should do a much better job teaching students how metal parts are machined, PCBs and ICs are made, plastics are molded, optics are ground and so on, he said. When you understand how the things we use every day are actually made, I think you become a more creati e engineer.

    fun fact

    Matt doesnt think a robot take over will happen anytime soon. Personally, I think we have bigger problems to worry about, such as global climate change, long before AI becomes a threat, he said.

    Throughout Edds 47-year career, he has developed, designed and marketed power transmission devices. He also provided selection and performance data to help customers with their machines. A lot of people think engineers have answers to any technical question, whether the subject is in the area of expertis of the individual or not, Edd said. Often times, the answer is available with a little research. Edd used to work with Horton Industrial Products, where he was responsible for the design and patent of clutches, breaks and torque limiters from conception to market ready. As a custom business unit manager, he was responsible for the design of special products for specific applications. He now has three patents for fluid-powered products and has written white papers on rotary and linear motion. During his time developing and designing, Edd found that a en ve engineers are the key to success. Engineers must pay attention to the markets they serve and design products that have appeal as usable items that are cost effective, he said.

    fun factEdd loves to spend time with his sons and their families. He can be seen at a variety of sporting evens or at car shows that range in subjects from the latest technologies to collectables.

  • Danfoss cutting energy consumption by half

    n Paul J. Heney Editorial Director

    G r e e n E n g i n e e r i n g

    3 0 DESIGN WORLD December 2015

    The International Energy Agency has stated that energy efficiency can deliver 38%

    of the greenhouse gas reduction required

    to avert climate change. Danfoss is now

    accelerating its own eff rts by introducing

    new ambitious climate targets.

    Most of the worlds energy consumption

    comes from industry and buildings, and

    the potential for cutting it is huge. Danfoss,

    wanting to be a role model, has set new

    ambitious targets for itself ahead of the

    COP21 climate summit in Paris. By 2030, the

    company plans to use half as much energy to

    run its business, and emit half as much CO2

    from the energy it uses.

    Worldwide, we deliver some of the most

    innovative and efficient technologies for

    saving energy, helping cities and companies

    to reach their targets, said President and

    CEO Niels B. Christiansen. Now, we are

    intensifying our own eff rts in the form of

    a new, ambitious climate strategy, which

    builds on what we have already done and

    achieved. We see this as a natural part of

    leading the way within the climate sector.

    The company is already making progress

    in living up to these targets. Between 2007

    and 2014, its net sales increased by 55%,

    whereas energy consumption dropped by

    29%. Danfoss has been running energy-

    saving projects, among other things, at the

    largest factories worldwide. Typically, this

    reduces energy consumption for operating

    the buildings by 25 to 30%. The savings are

    primarily obtained through the optimization

    of the systems controlling the ventilation,

    heating and cooling using their own

    products.

    Based on the positive experiences, the

    company is now intensifying its eff rts

    to energy-optimize the companys buildings

    all over the world. In addition, production line

    processes will be systematically examined for

    further energy cuts.

    Green energy sources are another focus

    area. In 2013, for example, the manufacturer

    set up a solar cell parklikely the biggest of its

    kind in Scandinavianext to its headquarters

    in Nordborg, Denmark. The park produces

    electricity corresponding to the annual

    consumption of 400 single-family houses, and

    has a total capacity of 2 MW. A 1-MW solar-cell

    system was also opened at the companys new

    campus in India last year. Moreover, the new

    campus has received the international LEED

    Platinum rating, whereby it is certified as a

    green and sustainable building complex. DW

    Ball screws are mechanical devices that convert rotational motion to linear motion with a minimal amount of friction.

    Ball screws are used in an array of applications ranging

    from low accuracy transport guides to high accuracy

    precision grade screws. They are also used in robots,

    machine tools and precision assembly devices.

    Twiflex offers the largest range of industrial disc brake calipers in the world. Spring applied units may be retracted pneumatically, hydraulically or electrically (depending on caliper design) while most direct acting brakes have some form of positive retraction device.

    Pneumatically Applied Brakes are best suited for light to medium stopping duties and for tensioning applications where a high degree of control is required.

    Hydraulically Applied Brakes address higher torque requirements, while spring applied calipers are essential where braking must be maintained in the event of supply system failure

    Mechanically Applied Units are suitable for light tensioning duties or where no external power is available. They may also be specified when designers wish to use their own means of actuation.

  • Brakes ensure precise control

    As products move along automated packaging systems, accurate positioning is key to operation. PBZ variable torque

    brakes handle needs for variable torque tensioning control in

    automated packaging systems and similar applications.

    Unlike conventional mechanical brakes, the variable torque

    brakes are magnetic particle brakes. They use self-contained

    magnetic particles that slow, stop, hold and restart a system with

    repeatable accuracy. The torque is independent of slip speed and

    is variable from zero to the rated torque.

    The brakes precise, fast engagement ensures accurate

    positioning without jolts or jerking motion. This feature enables

    repeatable positioning of plastic film in luding labels, bar codes

    and other packaging elements with accuracy. A gradual or fast

    engagement setting is adjustable for different application requirements. The adjustment range is variable up to the brakes

    control circuit capacity.

    Another feature: These brakes do not have components

    that can wear. They are unaffected by atmospheric conditions, so are suited for temperature extremes in a range of operating

    environments.

    Available in three 24/80 V models with rated torque of 3, 6

    and 12 Nm, all three sizes have a 400-rpm allowable rotation. DW

    This includes, for example, the development of

    The designed part had to accommodate the fixi g and

    assembly components as well as the cover. While the end

    product was injection molded, the entire prototyping was

    carried out with an X400 3D printer from German RepRap.

    Only when we are certain that no more modifications are required do we create the expensive injection mold, said Rene

    Schneider, project leader. Up to that time, we do everything with

    3D printing. Any faults or changes required by the customer

    are easy to rectify and implement. We previously had to wait

    several days for a new prototype, such as for CNC milled parts.

    But the 3D printed prototype is often already available in a

    matter of hours. The printing of this winding body took around

    10 to 12 hours.

    Thanks to the large build area of approximately 40 40 cm,

    Popp is able to print three parts at the same time.

    For Popp Group, compared to conventional prototyping,

    there are no disadvantages with 3D printing for prototyping.

    Prototypes are required to have the same properties as the end

    product, both mechanically and functionally, as well as with

    regard to their material characteristics. The PLA frequently

    used in 3D printing is ideal here for medical technology since

    it is non-imaging and is not therefore shown in an MRI scan,

    Schneider said.

    3D printing has become firm y established in product

    development at the Popp Group. Our X400 3D printer runs at full

    capacity, Schneider added. DW

    An intelligent steering option incorporates both a steering and a safety

    controller into an electrohydraulic actuator,

    saving development resources and

    accelerating time to market for OEMs across

    agriculture, construction, road building,

    material handling and specialty markets.

    The system connects directly with GPS

    to allow automatic steering for an array of

    off-h ghway machineryincluding tractors,

    combines and sprayers. It also improves

    driver comfort with Quick Steering

    functionality and enables joystick or mini

    wheel steering for all applications. Previous

    steering systems used an external safety

    controller to monitor the electrohydraulic

    section of the steering valve.

    The OSPE with PVED-CLS actuator

    option is part of the Danfoss Functional

    Safety Solution. Designed with the

    safety of machine operators in mind, the

    flexible software-based system comes preconfigured with a number of steering-specific safety functions informed by comprehensive safety analysis and

    customer research. It can be easily adjusted

    o f f - h i g h w a y04 D e s i g n f o r I n d u s t r y

    Steering system integrates safety

    to meet the specific output and safety requirements of each application. It also

    includes integrated electrical follow-up

    (EFU). EFU aligns the steering wheel with

    the tires to ensure precise, unwavering drive

    trajectories. With this automation comes

    easier operation, higher productivity and

    reduced driver fatigue.

    With PVED-CLS, system designers no

    longer need to ensure that multiple parts

    are communicating. Now that the PVED-CLS

    is in direct contact with system pressure

    and feedback from the LVDT transducer, the

    operator is able to react more quickly and

    accurately than with an external controller.

    When it comes to safety, this fast and

    precise reaction is crucial, and the tight

    sensor coupling also means less machine

    downtime and fewer false alarms. In case of

    a fault, the monitor gives operators manual

    control within the electrohydraulic safe

    state.

    In addition to improving functionality,

    the integration of the safety controller

    into the steering unit reduces the system

    complexity.

    The OSPE with PVED-CLS is certified by TV SD, the German safety validation

    organization, for functional safety of

    electronic equipment (SIL2 for IEC 61508)

    and functional safety of control systems (PL

    d, ISO 13849 and AgPL d for ISO 25119 [EN

    16590]).

    The PVED-CLS hardware is based

    on a fully redundant Category 3 system

    architecture. The system takes care of

    steering hazards off oad. Additionally,

    the PVED-CLS has received the E-mark

    stamp from VCA (the United Kingdom

    Vehicle Approval Authority). The E-mark

    is a general certification regarding EMC (directive ECE R10), which OEMs can use

    toward fi al vehicle homologation. DW

    The complexity of these systems is

    constantly increasing, for example, as

    robots are added to these systems. One

    way to reduce the complexity is to use

    tools inherent in systems like PLCopen. The

    function blocks in PLCopen can be used for

    all types of robot kinematics and even allow

    robots to be synchronized with multiple

    conveyor belts. The interfaces are also

    suited for integrating HMI applications for all

    types of kinematic systems.

    The robot can move freely during the

    synchronization phase, which also enables

    complex product manipulation. B&R offers a system in which the conveyor belt is fully

    integrated into the application. An external

    sensor that supplies information about the

    current position of the conveyor belt is all

    that is needed.

    The conveyor belt tracking system

    is hardware-independent, which allows

    the use of different drive systems with different kinematics. The application can be created quickly and easily upgraded at a

    later time. The robot can be replaced or the

    conveyor belts can be upgraded at any time

    without a significant amount of application engineering work. A large portion of the

    software can be used as is. DW

    US Cotton, a domestic manufacturer of cotton swabs, was considering the replacement of the pneumatic cylinders on one of its

    major production machines. The application involved picking a layer of

    cotton swabs out of the assembly section of the machine and placing it

    in a stack before going into the retail package.

    The company was looking for better control and reduced

    maintenance. Control, because operators had to make frequent

    adjustments to the machines to compensate for changes in air

    pressure. Maintenance, because the air cylinders in each of the several

    dozen machines had to be replaced every one to two months. The

    company needed an actuator that would last much longer.

    The search led the engineers to linear motors made by LinMot. These

    linear motors differ from others in that they are tubular-style linear

    motors, as opposed to open, track-style linear motors. The tubular-

    style linear motor actually looks and acts somewhat like a pneumatic

    Electric linear motors picked for swab application

    cylinder. The motors are sealed so they can operate in dirty environments

    and dont require any moving cables.

    Cost is always a factor in design, but its important to balance cost

    over benefit. In this case, energy savings can justify the price of the linear

    motors. But the staff t US Cotton needed convincing.

    The company said that it would volunteer machines to use test beds

    (along with some personnel) if LinMot would provide the equipment

    needed to perform a test. LinMot agreed. US Cotton chose one of the

    systems (linear motor and drive) and installed it on a machine to evaluate

    the technology. After running for more than 18 months, there were no

    adjustments required and no replacements needed.

    For the fi al test, LinMot and US Cotton enlisted two production

    machines to perform a side-by-side comparison between a pneumatic

    cylinder and linear motor. The air for the pneumatic cylinder (and only the

    single pneumatic cylinder) was supplied from a separate, free-standing air

    compressor connected directly to the cylinder.

    Test administrators used a standard

    compressor rated at 150 psi, 1.5 hp, 120 Vac,

    3.5 cfm (at 90 psi), with a 15 gal tank. The

    regulator on the compressor was set to 80 psi

    to match the normal running pressure used on

    the machine.

    To measure the energy used, an Allen-

    Bradley PowerMonitor 5000 was chosen. This

    revenue-accurate instrument detailed data

    about energy usage.

    The machines were each run for 30 min at

    a rate of 48 operations per minute. The energy

    consumed was recorded by the PowerMonitor.

    For that time, the compressor consumed 1.875

    kWh hours of energy. The machine equipped

    with the linear motor consumed 0.060 kWh.

    This meant that the linear motor equipped

    machine consumed only 3.2% of the energy of
