Hexagon displays machine tool innovation

Published

on

New solutions from Hexagon on display at EMO 2019 deliver faster, accurate, data-rich measurement integrated into the machine tool and a step-change in calibration technology.

Hexagon’s Manufacturing Intelligence division will display at EMO 2019 a range of ground-breaking technologies that address today’s machine tool measurement and calibration challenges while equipping manufacturers to evolve towards Industry 4.0.

Wolfgang Madlener, Product Line Manager Sensors at Hexagon, says: “Hexagon’s ongoing investment in developing smarter manufacturing hardware and software is resulting in innovative products that resolve manufacturers’ current issues and prepare production facilities for the future. For machine tool users this means new ways to more quickly and accurately take measurements on the shop floor and make real-time use of measurement data. Additionally, they can use ground-breaking solutions for calibrating and compensating machine tools.”

Among the innovations on display for the first time will be the LS-C-5.8 laser scanning solution for non-contact surface inspection on the machine tool. It meets customers’ growing demand for an easy-to-use, contactless solution for capturing surface measurement data quickly and directly on the production line. Hexagon is also showing its new ultrasonic touch probe for fully automated thickness measurement, the RWP20.50-G-UTP, which integrates directly with a machine tool. Measuring thickness often requires an elaborate manual setup, which includes the installation of external, manual ultrasonic measuring instruments. Hexagon’s RWP20.50-G-UTP ultrasonic touch probe automates and simplifies the procedure, as part of the machine tool installation, just like a regular touch probe.

EMO 2019 attendees will be able to see Hexagon’s most accurate touch probe for machine tools, the RWP20.50-G-HPP. This radio-wave probe deploys patent-pending laser-triangulation technology inside its measurement unit to achieve extremely high repeatability, low pre-travel variation and low 3D form error. It is ideal for capturing precise measurement results in 2D and 3D and measuring freeform shapes or checking machine kinematics. 

The data the LS-C-5.8, the RWP20.50-G-HPP and the RWP20.50-G-UTP capture will be available in real time on the shop floor, enabling manufacturers to quickly identify and address production issues. Data exchange is essential to smarter manufacturing and Hexagon will show how it has optimised the communication capabilities of its latest generation of radio-wave touch probes, with the introduction of the new RWR95.51 radio-wave receiver.

For manufacturers that rely on machining precision in the hundredths of millimetres or even micrometres, Etalon, part of Hexagon’s Manufacturing Intelligence division, has transformed the calibration of small and medium machine tools. The Etalon X-AX LASERBAR delivers a simpler, faster and more accurate way to monitor and calibrate small and medium machine tools and reduce the risk of expensive machining errors. It generates the complete geometrical fingerprint of a 3- to 5-axis machine tool in an automated way in one to two hours, replacing an entire toolbox of conventional calibration equipment for linear and rotary axes.

Less planning effort for material flow solutions

Published

By

With the inclusion of the new stacker crane and transfer cars in its planning software, Interroll has once again expanded the range of applications of the popular Interroll Layouter Tool. With this application, which can be seamlessly integrated into the AutoCAD design program, planners and system integrators can now visualize even complex conveyor systems end-to-end at the click of a mouse and make them available for quotation and ordering processes. By digitalizing the necessary process chain, planning times for customers can be dramatically reduced—by up to 90 percent, depending on the initial situation.

The ability to visualize technical planning has always been one of the central requirements in the project business with modern material flow solutions. But even today, the path from the first plant design to the detailed technical project planning, which leads to the preparation of a quotation and the concrete award of the contract, is in most cases still characterized by time-consuming breaks in the work processes. For example, initial visualizations of the overall solution must later be broken down to all the required individual components of the desired plants. The fact that this process step can be avoided is demonstrated by the Layouter Tool that Interroll makes available free of charge to enable customers worldwide to shorten their planning phase significantly.

“With our application, which can be seamlessly integrated into AutoCAD as a plug-in, planners and system integrators can not only visualize the planned conveyor solution based on the desired parameters,” explains Marcus Dörr, Global Product Manager for the Modular Pallet Conveyer Platform (MPP) at Interroll. “The Layouter Tool also simultaneously specifies all the necessary technical components of the respective solution. In addition, the plug-and-play modularity of Interroll’s conveyor platforms ensures that the engineering effort required to put together the overall solution is eliminated”.

The advantages of this approach are impressive: Already with his first design, the AutoCAD user has all the technical information for the desired conveyor solution and, in the case of special framework agreements, even the necessary price information. This means that the planning data can easily be reused for the subsequent quotation or ordering process.

The Interroll Layouter Tool can be used for Interroll’s modular platform offers, such as the Modular Conveyor Platform (MCP), the MPP, or the company’s flow storage solutions. The free application is available as a plug-in for a full version of AutoCAD from version 2014. The Layouter Tool is compatible with Windows 7 to Windows 10; Microsoft Excel is required on the workstation computer.

A surefire adrenalin kick

Published

on

In Europe´s biggest roller coaster, the Helix at the Liseberg amusement park in Gothenburg, POG 10 HeavyDuty incremental encoders from Baumer monitor the speed of the carrriage’s drive as it approaches the start ramp. The HeavyDuty technology guarantees high reliability and precision under extreme environmental conditions – serving up both thrills and reassuring safety for riders.

Liseberg in Gothenburg is Sweden’s largest amusement park. The Helix roller coaster is one of the attractions that swirls up an adrenalin kick. With a 1380 meter track, Helix is the longest looping roller coaster in Europe and the second longest in the world. It hurls its riders at up to 90 km/h through six loops and exposes them to up to five times their own bodyweight. This is the first time anywhere in the world where half of the riders, Helix takes up to 28, sit facing backwards, making the ride even more exciting. Before the start, the riders have to be brought to the start ramp at a height of 41 meters. Controlled asynchronous drives with 315 kW of power are used to move the carriages into the start position. The speed of this drive is recorded by the original Hübner Berlin POG 10 HeavyDuty encoder from Baumer. No easy task, as the roller coaster is freely exposed to the elements – heat from the sun, moisture from rain or wind currents. Hence the decision to go for HeavyDuty encoders from Baumer, making sure the riders experience the thrill as a pleasure too.

Reliability is critical

The POG 10 incremental HeavyDuty encoder and its sister model, the HOG 10 with hollow shaft, are among the most versatile product ranges of the Baumer HeavyDuty encoders. They deliver reliable speed data in a host of potential applications and operate under the toughest conditions. As a result, they help prevent failures and maintain the availability of machines and systems. This saves downtime costs in a host of applications. With the roller coaster, it even makes a valuable contribution to the safety of human life – a malfunction in the drive of a carriage would at best be annoying for the riders, and at worst a life-threatening experience.

The HeavyDuty technology of the POG 10 guarantees high reliability under challenging environmental conditions through numerous specific features. Thanks to solid and generously dimensioned wall thicknesses and a warp-resistant design, the die-cast housings are extremely robust and highly resistant to vibration and shock. Bearings at both encoder shaft ends and the metallic incremental disk offer huge power reserves and unparalleled durability through extreme resilience to axial and radial forces. For outdoor use, in a roller coaster for example, the excellent anticorrosive properties of the CX category of HeavyDuty encoders to EN ISO 12944, achieved through an optimal choice of material and high-resistant coating, are also extremely important. These properties allow the encoders to be used even on or in the ocean, in the Arctic, in the tropics or in the desert.

The combination of labyrinth and shaft seals also protects the inner workings of the HeavyDuty encoders from solid, moist and paste-like contamination. This sealing concept conforms to protection classes IP 66 and IP 67 within a broad temperature range of up to 95 degrees Celsius. Current-insulated bearings ultimately protect the ball bearings of the encoder from current flashovers, and this averts any impairment of the lubricant effect. The result is an almost indestructible full package that effectively prevents potential malfunctions and failures, even during tough continuous use in a roller coaster. This is all the more important as a replacement can get very costly – not because the encoder itself is expensive, but because it is typically mounted in barely accessible locations, as is the case on a roller coaster.

HeavyDuty as an all-encompassing performance promise

HeavyDuty means highly resilient. This is not only about a tight, solid housing and protection against the elements. The intrinsic values have to be right as well. “Of course, it’s always the strong ones, so to speak, that are used when the going gets tough, explains Steffen Günther, Head of the HeavyDuty Business Unit at Baumer. “Yet HeavyDuty offers an all-encompassing performance promise: such encoders must, first and foremost, function under extreme conditions at all times. Secondly, however, their signal accuracy must not suffer under these adverse conditions. For an encoder to be called HeavyDuty, it must be absolutely durable, impermeable and precise.”

Reliable precision is ensured by the interference-immune scanning function with highly robust, optical circuits (Opto-ASIC). This guarantees optimum electromagnetic compatibility with a burst strength for high-voltage pulses of up to 4 kV. In addition, the Enhanced Monitoring System (EMS) continuously checks numerous encoder functions, swiftly detects connection and encoder errors and transmits the encoder status to the inverter or to the control via an error output. The HeavyDuty encoders achieve the best possible SinCos signal quality through the LowHarmonics technology for outstanding control quality, low drive heat-up and high energy efficiency. The incremental square signal outputs also have short-circuit proof, powerful transistor drivers for peak currents of up to 300 mA. They ensure reliable signal quality even over long-distance transmissions of up to 350 meters.

These features – resilience and precision – make an important contribution to ensuring that the Gothenburg roller coaster riders are brought to the start ramp safely and at the correct speed. A good thing too, since this ascent to 41 meters is thrilling enough without any failures.

Baumer with Hübner Berlin as world leader for HeavyDuty encoders

Baumer guarantees to keep this all-encompassing performance promise every time with original Hübner Berlin technology through rigorous sample tests and by putting each and every HeavyDuty encoder through a full inspection before it leaves the factory. Resistance to electromagnetic fields, vibration, shocks, dust, hose water, salt spray and much more is ensured on test benches during series production. Detailed quality certificates confirm that these tests have been passed and give the customer the confidence that their encoder won’t leave them high and dry.

Baumer’s undisputed world leading position as a supplier of original Hübner Berlin HeavyDuty encoders is another such guarantee. The manufacturer can draw on experiences garnered in this encoder class since the 1950s. For 25 years now, the HOG 10/POG 10 product range has been considered the Non-Plus-Ultra in the segment. An original, often copied by the competition, but never equaled, in pursuit of offering more “Beyond the Standard” – more precision, more functionality, more resilience and more benefits for the user. A “more” that can be achieved only through the know-how created from decades of experience with the subject.

It can be assumed that the riders on the roller coaster in the Liseberg amusement park have no idea what’s going on. This promise of resilience and precision, however, keeps the operators safe in the knowledge that their ride will never become a roller coaster of feelings for them.
