Whether it is assessing the viability of a new IoT home technology for consumers or designing a component used in a new surgical medical device, research is core to the technical and technological development of most any product.

In an R&D environment, force testing helps to compare product materials, determine the strength materials and components, and evaluate environmental, ergonomic, and other features. Additionally, force testing is common across industries as a quality control measure to accurately check that a given group of products meet targeted design specifications, per performance, safety, and regulatory requirements.

Interface often works with engineers whose role it is perform research and development within their organization. R&D engineers use research theories, principles, and models to perform a variety of experiments and activities. Not only do R&D engineers create new products, but they often are responsible for the redesign of existing products.

Our goal at Interface is to help R&D engineers identify the best sensor-related products they can use to work through the problems they are seeking to solve. The products we provide validate findings through highly accurate sensor test and measurement data. There are some R&D applications that need just one or two load cells and basic instrumentation to conduct the project testing. Other times Interface is asked to create an application-specific engineered to order part or design a custom measurement solution to achieve the desired test and measurement outcomes. The later is often the case if a sensor is an actual part of the product design. Interface has helped R&D engineers assess all kinds of prototypes and early designs using our precision force measurement devices.

Force measurement is used throughout the product research and development lifecycle, from ideation and prototyping, to robust testing and eventual commercialization phases.

  • IDEATION: In the ideation phase, we provide force measurement solutions for testing materials for compatibility with the idealized product’s use cases.
  • PROTOTYPING: In prototyping, force sensors help engineers select a minimum viable product (MVP) design. Sensors are used in the lab environment to validate a product or component, or as an actual embedded sensors utilized for real-time feedback and performance monitoring.
  • TESTING: When a product moves into the testing phase, it ready for a more thorough batch of tests including cycle and fatigue testing. Our load cells, torque transducers and instrumentation are commonly used in these environments. Every product will require a sensor model that fits by specifications and capacity.
  • COMMERCIALIZATION: Finally, when a product is ready for commercialization, we provide products used to run a variety of tests to ensure the product is constructed in a way that is safe for the user and meets certain force related specifications for intended use.

To give you an example of how an R&D engineer utilizes force sensors, we have included a few application examples below.

R&D Testing for Bicycle Manufacturer

A bike manufacturing company R&D engineer created a new handlebar design. They need to test the handlebar concept for their bikes during the R&D phase to ensure they will perform for a rugged trail ride experience, while ensuring safety of the recreational equipment. The R&D team took the concept and conducted fatigue tests on their handlebars to observe its structure and performance durability before mass production.  Interface suggested using Interface Mini™ product SSMF Fatigue Rated S-Type Load Cells. Two of these s-type load cells are attached on either end of the bike’s handlebar stem, where it will measure the forces applied as the handlebar undergoes its fatigue test. Results can be measured, logged, and graphed with the SI-USB Universal Serial Bus Dual Channel PC Interface Module.

Research Rig Used for Testing Prosthetic Designs

Prosthetic limbs must undergo rigorous R&D testing prior to manufacturing. These critical apparatuses are tested for extreme loading that can occur during falls, accidents, and sports movements. Fatigue testing of prosthetic components determines the expected lifespan of the components under normal usage. R&D engineers use testing data to determine whether prosthetic materials and designs will withstand the rigors of daily use and occasional high load situations. For the R&D project, various configurations of compression and tension test machines can be used depending on the type of prosthetic device being tested. Often the same machine can be used for static and fatigue testing. For this application, an SSMF Fatigue Rated S-Type Load Cell is mounted between a hydraulic actuator and the device being evaluated. During static testing, loads are applied to the specimen using the load cell signal as force feedback control of the test machine. During a fatigue test, the actuator repeatedly applies and removes the force to simulate activity such as walking. Tilt tables may be used to apply forces at various angles to simulate the heel-to-toe movement of walking or running. The 9890 Strain Gage, Load Cell, mV/V Indicator with Logging Software was used to store the research data.

 

Electric Vehicle Structural Battery Testing for Prototype

Battery technology is critical to the evolution of electric vehicles, so there are a variety of tests performed on new innovations in EV battery technology. As electric vehicles push advancements in efficiency gains, structural battery packaging is at the forefront for optimization.

Also utilized were 6-Axis Load Cells to capture reactive forces transmitting through pack structure. Multi-axis measurement brings greater system level insight and improved product success. The tests performed using Interface’s force measurement products were able to validate the battery packs strong structural design.

Proving Theoretical Cutting Forces Of Rotary Ultrasonic Machining

Rotary ultrasonic machining is a hybrid process that combines diamond grinding with ultrasonic machining to provide fast, high-quality drilling of many ceramic and glass applications. This new method has been theoretically proven using computer models. Rotary ultrasonic machining generates forces of an exceedingly small magnitude. To prove this theory, any load cell used for measurement must be sensitive, while at the same time retaining high structural stiffness within a compact, low-profile envelope. Interface’s 3A120 3-Axis Load Cell was installed in the rotary ultrasonic machine to measure the forces being applied to a sample part. With clear signals and minimal crosstalk, the applied forces are recorded and stored using an the BSC4D Multi-Channel PC Interface Module. The 3-Axis load cell provided excellent data helping uncover the relationship between machine cutting parameters and the forces applied on the component. Using this knowledge, the machining process was reliably optimized for new materials and operations.

The role of Interface as it pertains to R&D is constantly growing as engineers create new innovations to solve a myriad of challenges throughout the world. We provide the most accurate and reliable force measurement systems to help advance technology across industries.

Interface Solutions for Machine Builders

/0 Comments/in /by

No matter the industry, if products are being made chances are industrial machines are involved in some part of R&D, testing, production, and distribution.

Engineers involved in the design and manufacturing of these machines require the highest quality sensors, tools and equipment. In addition, humans often lean on machines for very precise or repetitive tasks, this means that precision and reliability is key for every aspect of these machines.

Machine builders are the backbone of product development and production. They are responsible for building, assembling, and integrating components for stand-alone and multi-station automated machine tools and systems. These automated machine-tool systems are used in all sectors of manufacturing, including assembly, processing, and fabricating systems.

Interface plays a critical role for machine builders, for those that design one machine or manufacture machines at scale for users around the world. We supply machine builders with precision load cells, torque transducers, instrumentation, data acquisition devices and accessories. They lean on Interface because of our experience in supplying the world solutions utilized for industrial product testing and production across all kinds of industries from agricultural machinery to medical testing machines.

The accuracy and quality of our products is why machine builders rely on Interface. In addition, our experience and diversity of product has led machine builders and engineers to choose Interface force measurement sensors throughout their careers. In fact, Interface has served machine builders for more than 50 years. It is a relationship and role we know very well.

The world of machine building has also changed over the years. In the past, machine builders used force sensors primarily to test products before going out to the market. This is still a prominent use case amongst product engineers. The fast-rising use cases over the past decade comes from the demand for smarter machines, automation and miniaturization of products.

Today, more machines builders and OEMs are designing force sensors directly into machines to allow users to activate components, monitor data on the machines in use for real-time feedback and adjustments. This type of innovation using sensors has opened opportunities for Industry 4.0 connectivity between machines.

To get a better idea of how machine builders are using force sensors, Interface has developed a wide range of applications notes to provide real world examples of force measurement in action in the machine building world. We have included a few of those examples below.

Metal Press Cutting Machine

A customer wanted to test the amount of force it takes to cut through different thicknesses of metal on their metal press cutting machine. They also wanted to ensure their metal press cutting machine is working properly and understand its maximum limitation. Interface suggested installing their 3AXX 3-Axis Force Load Cell underneath the plate where pieces of metal are placed to be cut, or punched holes in. When connected to the BX8-HD44 BlueDAQ Series Data Acquisition System, the force results of different metals being cut will be displayed, graphed, and recorded on the customer’s PC. It also has an analog output that can connect to the machines PLC in case of an overload. Using this solution, the customer was able to determine the different number of forces it took for their metal press cutting machine to cut through different types and thicknesses of metal. Read more here.

Snack Weighing and Packaging Machine

A snack manufacturing brand wanted to weigh the amount of their snacks that is automatically dispersed into the bags during the packaging process. In this case, they wanted to weigh their potato chips being packaged and ensure the potato chips are at the exact weight needed due to regulatory standards. Interface’s solution was to use multiple SPI Platform Scale Load Cells and install it to the potato multi-head weigher and packaging machine. The SPI Platform Scale Load cells were installed inside of the mount that attaches the head weigher to the packaging machine. Force results from the potato chips are read by the load cells and sent to the ISG Isolated DIN Rail Mount Signal Conditioner, where the customer is able to control the automated production from their command center. Using this solution, the customer was able to determine the weight of the potato chips being distributed into their bags with highly accurate results. They also were able to control the automated production process with the provided instrumentation. They will use this same weighing method for other snacks that need to be packaged. Read about this application here.

Tablet Forming Machine

A pharmaceutical company needs to precisely monitor the forces applied by the tablet (pill) forming machine to understand the relationship between raw material, die set, forming force, and motor cycle speed. Optimizing the equipment will improve productivity and efficiency of the tablet forming process, while reducing losses. For maximizing production and monitoring the process, Interface suggested a WMC Sealed Stainless Steel Mini Load Cell (10K lbf Capacity) be mounted in the section of the downward press bar. The load cell was then connected to a 9320 Portable Load Cell Indicator to collect the needed data. Read more here.

Load Cells for Consumer Product Applications

/0 Comments/in /by

Typically, when engineers talk about load cells and their multitude of uses, it is assumed the applications are large-scale industrial projects like airplanes, rockets, and automobiles. However, did you know Interface load cells are regularly used for research and development (R&D), manufacturing, and end-of-line testing for countless consumer products?

Force is one of the most critical pieces of measurement in product development. This is especially true for consumer products that we interact with every day. Load cells are the tools that ensure products feel, handle and react the way they should in a consumer’s hand.

Here are a few examples showcasing how load cells touch almost everything the consumer touches.

A perfect example of a consumer product where force measurement plays a critical role in human interaction is in the abundance of numerous touch screens. Load cells are used in the R&D process to measure the accuracy, pressure, and sensitivity of the touch screen consumer interacts with on a minute-by-minute basis. The little things we don’t think about when using a tablet or smartphone, such as the smooth feeling of scrolling through social media pages, is possible because of testing using a load cell.

Another common consumer application type of load cells being used to improve product feedback and interaction is with simulation programs. High-end flight simulators often use load cells to measure the force of haptic feedback on the joysticks or chair when interacting with a flight simulator. The feeling of drag or rough winds a pilot experiences in a simulation is measured and refined for accuracy using a load cell.

Load cells are also an integral part of the manufacturing process for consumer goods. If you’ve ever seen a piece of candy with a logo stamped on it, chances are high a load cell was involved in determining the level of force to apply an exact brand stamp. Load cells are used on the stamping machine to ensure the right amount of force is used to apply the logo without crushing the candy.

In the food and drug industries, load cells are used in manufacturing facilities and on a wide variety of packaging machines. They are used for ultrasonic welding, which is the sealing process for plastic, paper or fabric shopping bags, garbage bags, and diapers. Potato chip assembly lines use load cells to weigh the bags as they fill them with chips to know when to stop and move on to the next bag. And the same stamping process used for candy in applying labels is used on pills.

Companies also incorporate load cells in end-of-line product testing. Furniture often goes through rigorous testing to ensure reliability. The furniture has various loads applied to it to confirm it can hold heavier weights over time, the furniture can also be bent and flexed to check the quality of the materials.  To reduce waste and ensure product quality, many consumer bottles use a torque transducer for end-of-line testing to test the proper cap implementation.

Batteries are another consumer product that goes through R&D and end of line testing to measure the force needed to damage the casing.  This is used to eliminate poorly designed and assembled batteries, as the acid inside can do immense harm if a child or adult is able to accidentally crush one.

Force measurement is also something that plays a role directly in the products we use. For instance, scales we use to weigh ourselves, food, and more, have load cells in them. Racecar gaming brake pedals are another example. High-end racing simulators need their brake pedal to be very accurate at measuring the amount of force applied to it to react as a real car would. Load cells are implemented in the base to provide accurate force readouts to the simulator in real-time.

Most products we all interact with every day have had some force testing or are currently using a sensor to manage its use and reliability.  Other consumer products that use Interface load cells, in all capacities and models, include treadmills, skis, bicycles, coffee makers, gaming brake pedals, boats, golf balls, desk drawers, guitars and robotic vacuums. And that is just to name a few.

Load cells and other force measurement tools like torque transducers are an integral part of developing, testing, and manufacturing reliable and accurate consumer goods. Think about this the next time you are handling your smartphone or carrying in groceries from the store. None of it would be possible without the use of force measurement equipment.

Interface Celebrates Made in the USA

/0 Comments/in /by

Manufacturing is essential to the U.S. economy, with an estimated $2.38 trillion contribution and accounting for nearly half of all exports. This equals about 11.4% of U.S. economic output. (Source: Bureau of Economic Analysis)

With approximately 250,000 firms in the manufacturing sector in the U.S., Interface is proud to be counted as one of them. Companies with manufacturing operations solely in the U.S. are considered an anomaly today. With a great deal of U.S. production occurring outside the country, there are fewer enterprises that sustain domestic manufacturing success. As we approach Independence Day on July 4th, Interface is reflecting on how honored we are to be a U.S. manufacturer for more than a half-century and counting.

Though our production is domestic, our reach is global. Interface load cells and torque transducers have been used in nearly all industries providing reliable test and accurate measurement capabilities to international market leaders in aerospace, automotive, energy, medical, education, and other top manufacturers. We’re proud to say our products are “Made in the USA.”

We began designing and manufacturing load cells and other force measurement equipment in 1968 when Richard F. Caris started Interface in his garage. Since those early days, we have grown to become one of the most trusted names in the industry. And not once in our history have we considered moving production out of the U.S. We maintain the highest degree of performance by managing the entire process, from design and machining, to strain gage manufacturing and assembly at our headquarters in Scottsdale, Arizona.

One of the most satisfying aspects of having U.S. manufacturing operations is contributing to our country’s economic prosperity and innovation. The National Association of Manufacturing (NAM) presented the following facts on the state of U.S. manufacturing, and Interface is appreciative to be an integral contributor to these milestones.

NAM Facts (Source):

  • U.S. manufacturers perform 64% of all private-sector R&D in the nation, driving more innovation than any other sector.
  • For every $1.00 spent in manufacturing, another $1.82 is added to the economy.
  • There are 12.82 million manufacturing workers in the U.S., approximately 8.5% of the workforce.
  • Over the next decade, 4.6 million manufacturing jobs will likely be needed, and 2.4 million are expected to go unfilled due to the skills gap.
  • Over the past 28 years, U.S. manufactured goods exported have quadrupled.
  • Manufacturers in the U.S. export nearly half of U.S. manufacturing output.
  • Taken alone, manufacturing in the U.S. would be the eighth-largest economy in the world.

Interface is focused on our contributions economically, by supporting innovation and job growth through a robust manufacturing role in the production of the world’s leading force measurement solutions. It’s definitely worthy of a holiday celebration.
