Interface Solutions for Machine Builders

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.

Machine builders require the best test and monitoring equipment. Interface has backed professional machine builders, machine design engineers, machine manufacturers and those that utilize the equipment for many years with top-of-the-line force sensing solutions.  Whether you are looking to build a machine, design machine tools and equipment or embed sensors into machines, we are here to help.

New Interface Case Study Exams Weighing and Scales

Test and measurement are used in the development and monitoring of manufactured goods across all industries. With a history of producing force measurement solutions for more than five decades, Interface has supplied a myriad of sensor devices for hundreds of thousands of different use cases and applications.

From the scales we use in packaging centers to the enormous weigh check equipment used in transportation, weighing and scale measurement solutions are instrumental in the successful design, engineering, launch, and maintenance of products and components.

Many of the earliest force sensors were designed for the purpose of weighing objects, and they continue to be a large part of test and measurement today. As products evolve and new inventions enter the market, sensors must maintain their durability, quality, and accuracy for large and miniaturized uses. Therefore, you see inventors and innovators turn to Interface today for sensors that are designed for use in robotics, IoT, and factory automation equipment used for weighing.

Historically, the only difference between now and then is that Interface has perfected accuracy in measurement across with an extensive range of force sensors models, configurations, sizes, capacities, and specification requirements that can measure weight at “jumbo” scale, as well precisely measure exceedingly small, minute forces as an embedded sensor.

Determining accurate weight is a key data point manufacturers need throughout a product lifecycle. Whether they need the information for transporting an object, lifting the object, or just creating a specification sheet, accurate data for weight measurements is fundamental for safety and function. This includes weighing single and combined parts in early design, weighing the manufactured equipment during assembly and production, using scales for weighing output with exact measure, as well as obtaining real-time weight in distribution and transport.

To accomplish this, Interface provides a host of load cells and instrumentation devices. Since our first load cells were designed in 1968, we have built millions of these products for engineers and designers that require the highest precision force sensors for accurate and reliable data collection in test and measurement (T&M). Our customers represent a wide swath of industries, products, equipment types, tools, and electronics that depend on us for proving accuracy, consistency, and reliability in performance in T&M.

In our latest case study, we outline four weigh and scale use cases that utilize Interface sensor technologies. Defined weight as a product specification requires extreme accuracy in measurement. Utilizing precision force sensing solutions and instrumentation enables product engineers and manufacturers to collect data and use it as part of the product design.

Accuracy Matters for Scales and Weighing focuses on weighing and scale applications used with heavy machinery, medical devices, operational containers, and distribution solutions. In each of these instances, utilizing weight in the design, build, and supply of these products is fundamental to each use case and the success for the product.

Manufacturers and design engineers of these robots come to Interface during the stages of research and development, product engineering and refinement, and testing to perfect surgical use cases. The sensor technologies we provide are preferred in these processes and in final integration due to the fact these devices are highly regulated and require the utmost in accuracy and reliability.

The types of surgeries currently being performed with robotics include what were once considered invasive and a higher risk of failure such as coronary bypass, removing cancer tissue, transplants, laser incisions, and more. With surgical robotics, the medical professionals rely on precision to perform these surgeries with as minimal invasion as possible.

The product development process for surgical robotics is extremely meticulous and requires a wide variety of tests to confirm the accuracy of the product. One of the key components to testing in this field is force measurement. As you can imagine, force plays a massive role in surgical robotics. Every action performed needs to be forced tested to ensure that whatever the surgical task, the robot is doing it with precision.

For surgical robotics, minute forces need to be measured because they are working with highly fragile subjects within a human body. To measure these tiny forces, Interface offers a variety of Interface Mini™ Solutions.  Interface Mini Load Cells are used for light touch, light weight, or for less space. Our miniature load cells provide exceedingly accurate measurements similar to our full-size load cells with proprietary alloy strain gages. They are used in R&D, test and for OEM use in robot components.

All our miniature beam load cells, load cell load buttons, load washer, miniature tension force load cells, S-type load cells, and sealed stainless steel load cells are commonly used based on their capacity and designs.  A variety of our load cells can be used in an off-the-shelf application. Our engineers can also work with you to design custom load cells to fit your exact needs, which is common in robotics.

Interface recently developed an application note to outline how force measurement can be used in testing force feedback using a combination of load cells, torque transducer and data acquisition device on a robotic surgical device.

Robotic Surgery Force Feedback

A biomechanical medical company wanted to test the force, torque, and tactile feedback from their robotic arm for invasive surgery. The surgeon’s movements are mirrored by the robotic arm during surgery, and it was essential all haptic force feedback is measured to ensure safety during invasive surgery. A number of Interface’s force and torque measurement products were suggested for this robotic arm. These includes our load button, S-types, Mini overload protected torque transducers and DAQ instrumentation.  Included below are the roles of each device:

Each one of Interface’s load cells or torque transducers played a part in the ensuring the safety and functionality of robotic arms during invasive surgery. The force feedback that was measured from the robotic arm ensured that the robot used the perfect amount of force when using surgical tools that create incisions during surgeries. It also measured the torque being produced, ensuring the robot arm was moving smoothly and at the right speeds. Read the application note for this surgical robot here.

This is just one example of Interface’s work in robotics, and surgical robotics specifically. There are a growing number of devices used in special, precision surgeries that utilize force to perform its task.

Using this data, they’re now able to make improvements to the design. Read more about this prosthetic load and fatigue testing application here.

Stent And Catheter Testing

For this specific use case, large testing rigs that contain approximately a dozen Interface load cells are used to test stents and heart valves that are surgically implanted into patients. The rigs subject the stents and heart valves to thousands of stress tests over months to determine their material properties. Stents stay in a patient’s body for the rest of their life, so accuracy and durability are extremely important. This application makes use of Interface’s Miniature Beam Load Cell product line, which is overload protected. This product line is extremely reliable and has never had a reported fatigue failure. Included below is another application example.

In this application note, the customer needed to apply known forces to stent and catheters to ensure they pass all necessary strength and flexibility testing. Interface’s solution was to use a MBP Overload Protected Beam Miniature Load Cell that is placed behind the guide wire for the stent or catheter. The motor will spin the linear drive and push the load cell and guide the wire through the testing maze. MBP Overload Protected Beam Miniature Load Cell is connected to the DIG-USB PC Interface Module. All forces are measured and stored on PC. Using this system, the Customer was able to perform required testing and log to PC, followed by being able to review results and take actions as needed.

New Interface White Paper Highlights Turning an Active Component into a Sensor

The most common uses of force measurement in OEM (original equipment manufacturer) applications are when a force sensor is designed into a product that will be produced at mid to high volumes and provides real-time force feedback on certain product functions in use. Utilizing sensors as a feature enables data acquisition over time to monitor forces and understand how those forces effect product efficiency, safety, quality or all of these performance metrics. This ultimately is used to design a better product, in the current state and for future enhancements or to know when a product is performing best or risks breaking down.

Did you know that there is another application of force sensors in OEM applications that is playing a large role in the factory of the future? This is when we turn an active component into a sensor and use that data to create automated actions. This solution is used when there is a desire to take a moving component within a system and make it smarter, ultimately allowing it to make data-based decisions on its own.

For example, the manufacturing industry is using force sensors on machines within a production line that are responsible for picking components up for visual inspection. The sensor is integrated into the grabbing component and can tell the machine the exact force to use when picking up the component as not to damage it. This is a critical capability when dealing with expensive and delicate components that can break under too much force. In the past, a force measurement sensor would have been used only to test this functionality. When the sensor is designed directly into the machine, the user can both test beforehand and monitor and automate processes in real-time.

The need for this type of capability is growing rapidly amongst manufacturers across a wide variety of industry including aerospace and defense, industrial, medical, automotive, industrial automation, assembly and more. To further outline the potential for these types of solutions, Interface developed a new white paper that details  how sensor solutions for OEMs work with specific examples of the benefit of turning an active component into a sensor.

WHITE PAPER EXCERPT

OEM SOLUTIONS: TURNING AN ACTIVE COMPONENT INTO A SENSOR

The age of industrial automation and big data is upon us. Manufacturers that fall behind in equipping their facilities and products with innovation that allows for automated processes, remote monitoring and better efficiency through technology, will quickly fall behind. This is due to the fact that automation helps to significantly improve process quality because it eliminates human error. It also creates long-term cost savings by speeding up several processes, or by helping to monitor products in use and in real-time to optimize performance and stability over time through better data collection.

Force Solutions for Medical Tablet Forming Machines

In the medical and healthcare industry, accuracy is an absolute imperative in the devices used in every stage including diagnosis, surgery, health monitoring and even after care. This also applies to the specialized equipment used by pharmaceutical manufacturers, in both design and maintenance, when producing medicine and other healthcare related products.

When it comes to product development in the United States, not only do med devices and pharmaceuticals need to pass rigorous FDA regulations, but they must also be proven to serve patients and doctors safely. This results from robust test and measurement data requirements before seeking clearance. These same types of fundamental safety requirements of testing are also standard in most developed countries when seeking approvals before release.

Medical industry manufacturers turn to Interface because our force measurement solutions are designed for high performance test and measurement, in both accuracy and reliability. There is also a high demand for Interface’s ability to customize solutions to meet the exact requirements of these sensitive applications.

In a variety of medical device applications, one noted example is Interface’s role in providing various miniature beam and in-line load cell solutions with ten times the overload protection to protect against accidental shock loads. Our torque transducers provide rotary and reactive measurement to accurately track light movements required to control prosthetic fatigue testing, surgical equipment, knee or hip replacement and other medical devices. Other Interface solutions include multi-axis sensors for multiple channels of measurement in one housing. Read more about these types of medical applications here.

Interface provides force measurement solutions for a wide variety of products and machines that help biotechnology and pharmaceutical product engineers to design, test and manufacturer devices of all shapes and sizes. When it comes to equipment used in the manufacturing of medicine, Interface products are used to optimize production and reduce waste.

TABLET HARDNESS TESTING

In this application, a pharmaceutical tablet producer wanted to test and monitor the hardness of the tablets being created in their tablet forming machine. Interface’s SML Low Height S-Type Load Cell was mounted to the hardness device inside the tablet forming machine. The SML Low Height S-Type Load Cell was then connected to the 9870 High-Speed High Performance TEDS Ready Indicator to record the force measurements.

TABLET FORMING MACHINE OPTIMIZATION

For a tablet forming machine optimization project in Europe, a pharmaceutical tablet producer wanted to monitor the forces applied by the tablet forming machine in an effort to understand the relationship between raw material, die set, forming force, and motor cycle speed. The goal was to improve productivity and efficiency of the tablet forming process, while reducing losses such as cracked tablets or voids, by adding a dimension of feedback that could be used to assign specific press adjustment criterion for given inputs. An Interface Model WMC Sealed Stainless Steel Mini Load Cell 10K lbf was mounted in the section of the downward press bar. The machine was modified to accomplish this. The load cell was then connected to a Model 9320 Portable Load Cell Indicator to collect the needed data.

TABLET MACHINE HARDNESS CALIBRATION

Our partners in Germany also had the opportunity to work on a calibration project for a device that tested the hardness of tablets, such as a medicine in tablet form. The reason for this type of device is because medical tablets are overly sensitive to compression force when being formed and when ready to be shipped. If the tablets hardness isn’t tested properly, consistency in size and shape is nearly impossible. The need for force testing is because the device must provide very minimal and accurate forces to the tablet for product consistency. When this is applied to tablets that are used in medicine, accuracy in dosage is fundamental and an absolute necessity.

The customer required a unique solution to properly re-calibrate the device. They needed a mini-load cell the size of a sugar cube that replaces the tablets and fits horizontally in the tablet test-box. A special cable exit was also critical for the compression only calibration application.

Interface provided an MCC Miniature Compression Load Cell which can measure forces on its side with a special cable exit on the flat side that attaches to a calibration indicator, such as the Interface battery powered handheld indicator and datalogger Model 9330. The MCC load cell calibration set compares the applied forces with the hardness tester to make sure that the tablet hardness tester uses the correct force for future tablet hardness tests. The BlueDAQ software included in our indicator helps to log and compare the data of the MCC reference load cell.

In the past, the customer’s medical tablet machines had to be rebuilt for calibrations, or a complex mechanism had to be integrated to enable vertical calibration. With Interface’s new solution, the customer successfully verified and calibrated the tablet hardness tester machine horizontally to conduct accurate hardness testing on tablets in the future. Interface’s MCC Miniature Compression Load Cell was perfect due to its small size, and convenience in measuring the forces on its side.
