6 6 Newsticker CoreView Hexagon Metrology News New software version from Cognitens The latest version of CoreView is perfectly suited for the Cognitens WLS400 automated and manual white light measurement systems. It offers improved capabilities in measuring a work piece s geometric characteristics as well as 2D cross section analysis tools. Among other enhancements version 5.5 includes measurement and GD&T inspection of planar geometries broadening the Cognitens WLS400 system s application support and 3D visualization tools that allow users to measure sheet metal features faster and easier than before. Version 5.5 supports a new set of sensor lenses with 360 x 360 mm field of view used for measuring smaller parts and in reverse engineering applications. The new CAD import engine from Hexagon Metrology offers faster and more robust loading of 3D files. Accelerated data acquisition and parallel processing shorten the time required to generate a full inspection report. Leitz PMM-F in newly opened laboratory at the University of Bremen In Germany, the first university laboratory for the inspection of large gear wheels has been opened. It is located at the University of Bremen and was created by the Bremen Institute for Metrology, Automation and Quality Science (BIMAQ). The Bremen researchers can now measure toothed gear components from wind turbines with the aim of extending the life of large gearboxes. The measurements are performed on a Leitz PMM-F , a coordinate measuring machine (CMM) manufactured by Hexagon Metrology (measuring range 3000 x 2000 x 700 mm). In the laboratory there is also a Leitz Reference with a measurement range of 1000 x 700 x 600 mm. The goal of BIMAQ is to establish this laboratory as a certified testing authority for large gears. 1000th DEA GLOBAL CMM Hexagon Metrology has produced the 1000th DEA GLOBAL CMM. The machine was ordered by the Hirschvogel Umformtechnik GmbH in Germany, one of the most successful manufacturers of forged steel and aluminum parts. The company uses this CMM to measure un-machined and pre-finished parts for the automotive industry such as injection systems or parts for drives and gear units. Employees of Hirschvogel Umformtechnik GmbHm are already experienced in working with GLOBAL machines as in total more than ten DEA GLOBALs are used in the factory in Denklingen. Hexagon Metrology strengthens its presence in the Chinese optical vision industry Hexagon Metrology entered a joint venture with Dongguan Seven Ocean Metrology Vision Co., Ltd, a leader in vision measuring technology with many patents (hereafter referred to as Seven Ocean Metrology Vision) in China. Seven Ocean Metrology Vision has won many awards from relevant government departments for its technological innovations. Its products have been used in many industries such as telecommunications, electronics, automotive, plastic and machine processing. This is an important step for Hexagon Metrology s expansion in the Chinese optical vision industry and will positively strengthen its competitiveness in the Chinese market. EMO-Award for m&h for best innovation in the category Measuring At the EMO exhibition in Hannover, trade magazine MM-Maschinenmarkt presented eleven awards in ten categories. The jury praised m&h Inprocess Messtechnik for producing the best innovation in the Measuring category. At the event, the company s PC-DMIS NC Gage software package and Kinematic Setup module made their premières.

7 Newsticker 7 Renewed contract between Hexagon Metrology and EADS Hexagon Metrology and EADS, the parent company of Airbus, renewed their framework contract for all metrology products from Leica Geosystems until the end of The contract between EADS and Leica Geosystems has been in existence since Leica Geosystems Metrology Products are widely used by EADS for build/inspect processes of tools and parts and enable metrology-assisted assembly. They help the company to achieve the short production cycles and cost efficiency in a highly demanding industry sector. New version of PC-DMIS NC Gage V2.0 and new 5-axis Kinematic Setup option This new version of the software provides a complete measuring solution for modern CNC machines and makes it possible for the operator to use his machine considerably more efficiently than ever before. Self-explanatory symbols activated by function buttons on the touch-screen make programming easier and quicker. The integration of this new software version into the controller makes available considerably more measuring cycles than can be found even in German control programs. Thanks to this special product innovation, users of machine tools with FANUC or OKUMA controls now have a comprehensive range of measuring functions at their disposal. The Kinematic Setup for 5-axis machines option offers the user some completely new possibilities. With this function the machine can check the accuracy of the 4th and 5th axes at any time and automatically overwrite the compensation values if necessary. New standard laser tool setter LTS35.65 from m&h The new LTS35.65 standard laser tool setter from m&h avoids problems during calibration and operation. Its standard laser has a pneumatically operated optics cap and can even measure in purge air to prevent any possible build-up of dirt on the laser optics. The new system is sealed to IP68 standard and has a special high-velocity nozzle directed at the point of focus. It is available with a choice of three measuring ranges. The gaps between the laser sensors are either 90, 160 or 300 mm and therefore also allows you to measure large probe heads. The LTS35.65 is a cost-effective alternative to high-end laser tool-measuring systems. New TESA TWIN wireless inductive probe TESA has broadened its offer of TESA TWIN wireless inductive probes and the bi-directional interface specifically designed to work with them. Whether the new TESA TWIN probe is used within a multigauge measuring system or with manual devices this probe supplies consistent, high-precision measurements, eases the task of maintenance and overcomes the barriers to mobility caused by the cables attached to conventional probes. The new interface can manage up to four probes without a computer and up to 64 probes with a PC. Both types of probe can be combined in a single application. New TESA RUGOSURF 20 roughness tester The new TESA RUGOSURF 20 roughness tester, which is compact, robust and easy to use, is capable of measuring 15 parameters with their tolerances in accordance with the applicable standards. It is suitable for everyday use on the shop floor, even in the most demanding conditions. The instrument accepts a wide range of probes and accessories for measuring various surface roughness parameters.

8 8 Technology It s tough at the top As working tools for production environments, portable measuring arms and laser trackers have a hard time during a typical day s work. For this reason, Hexagon Metrology is equally hard when testing these instruments. Components weighting 80 t. Measuring jobs in different places all over the world. Operating in difficult, dusty environments or on the vibrating floor of a production hall. These are the conditions under which portable measuring machines from Hexagon Metrology must show their capabilities and demonstrate their robustness. Reliability means a lot to Hexagon Metrology. Users shouldn t have to take special account of rough everyday industrial surroundings, it is obvious that we should consider it in the development of new products. Portable coordinate measuring machines undergo endurance tests specially designed for their fields of application. IP54 tests in rain and sand storms The Leica Absolute Tracker AT401, a portable measuring machine for very large components, achieves an IP54 rating. IP is short for Ingress Protection. The international IP rating describes the degree of protection a device housing gives against contact with internal parts, foreign bodies and water. IP54 means that a device is protected against dust and splash water from any direction. The Leica Absolute Tracker AT401 is therefore perfectly prepared for industrial use. Leica Geosystems went over the Laser Tracker with a fine tooth comb to achieve this degree of ingress protection. In addition to the usual mechanical endurance tests, the Leica Absolute Tracker AT401 also shows what reliability really is in the dust chamber and under the shower. Exposure to a simulated sandstorm and hours of rain usually means the end for a precision optical instrument. But not the AT401: even after hours of dust or simulated rain in the tests, it remains fully functional. Unshakable confidence Portable measuring arms manufactured by ROMER are particularly well known for their mobility. Moving measuring systems from one place to another happens everyday for ROMER users. Measuring arms may not just move between production halls their travels typically include trips between cities, countries or even continents. The ROMER Absolute Arm is well protected in its transport box to minimise mechanical loads during transport. However, vibrations have really damaging effects on most measuring instruments - therefore the ROMER Absolute Arm must be able to show that it still retains full accuracy, even after long-term exposure to strong vibrations. In practical tests too, such as all-day car journeys or as freight on lorries or aircraft, ROMER developers check that the ROMER Absolute Arm continues to function reliably. These forms of transport not only create vibrations. The ROMER measuring arms are often moved in extreme temperatures: for example, in a car boot under a relentless sun or over an icy winter night. These conditions are a real challenge to developers. By meeting these challenges, they can be confident that the ROMER Absolute Arm always delivers its customary reliable accuracy, even in storage conditions that are anything but ideal for a high-precision measuring instrument. Reliability is a tradition at Hexagon Metrology: the first laser tracker ever made by Leica Geosystems in 1990 serial number 001 is still in use today at a US-American aircraft manufacturer. An even longer history of use is claimed by some ROMER System 6 instruments from 1986: they have been in action everyday for 25 years providing quality assurance in the French automotive and aircraft industries.

11 Cover 11 New vision for medical part validation Advanced software makes vision and multi-sensor inspection a mainstream tool for medical part analysis and inspection Accurately validating the dimensional specifications of medical parts is a crucial aspect of design and product development. Often, however, medical parts can be too difficult to measure with conventional tactile measurement systems. Part features may be too small for, or out of the reach of, hard touch probes. Soft and pliable materials can deform from contact measurement. Contact probes might scratch highly finished orthopedic products. Fortunately, vision and other non-contact probing technologies let users rapidly collect vast amounts of dimensional information for design analyses and subsequent part validation. The technologies use powerful CAD-based programs that let measurement systems operate in 2D, 2.5 D, and 3D modes while collecting data that can be used both to validate dimensions and analyze designs and manufacturing processes. These advancements were hard-won as vision-system software developers spent decades creating proprietary algorithms for accurately capturing images and transforming them into discrete points of data that could be automatically compared to nominals in the CAD model and that was just the beginning. Current refinements to the software used with vision and multi-sensor metrology systems should be of great interest to medical-device developers. Algorithms augment optics A perceived barrier to using vision and multi-sensor measurement systems as primary equipment for medical part metrology has been the idea that adjusting the systems for appropriate lighting, contrast, and edge-detection sensitivity required too much specialized knowledge for the average user in the metrology lab. This may have been true at one time, but it is no longer the case. Many powerful new algorithms in vision-measurement software effectively automate these adjustments, allowing for consistent measurements from part to part and vision machine to vision machine. The subjectivity of making manual adjustments to optimize contrast is a legitimate concern. Optimizing contrast substantially improves measurement accuracy by improving the vision system s capability to detect edges and compensating for the tendency of light to bend around the edges of cylindrical surfaces, thereby shortening measured distances. Today, special algorithms automate the adjustment of contrast levels. At the touch of a button, the algorithm makes a series of rapid iterative adjustments until an optimal and stable level of contrast is gained. Another potential source of vision measurement variability is caused by the differences in light sources (halogen

12 12 Cover or LED) used to illuminate the parts and the ambient lighting conditions in different plant locations. It is easy to correct for these variations when the measurement software includes algorithms that let the user compensate for these factors just as they would calibrate a probe on a CMM. Unlike tactile probes, cameras do not touch the edge they measure. Therefore, edge detection must rely on the accurate interpretation of data the vision software receives from the camera. Fortunately, advanced vision measurement software can tune its edge-detection algorithms to account for both the part s surface and the illumination conditions. Breaking bottlenecks Until recently, quality assurance was one of the biggest bottlenecks in medical-device development. Advances in vision and multi-sensor software now help many harried quality assurance personnel keep pace with the frenetic pace of development. Vision systems were traditionally programmed in a teach-and-learn mode. This meant that while users were developing measurement routines, the machine was not measuring parts. Today s CAD-based vision software lets users develop part programs off-line, while the vision system continues to measure. This does not mean that programmers must work with unfamiliar software and an unfamiliar interface. The best of the new vision metrology software looks the same in online and offline modes. It can also generate a view of the part that accurately simulates what the camera would see if it were working on an actual part. A big advantage of off-line programming is that users do not need to have the physical part in hand. Quality assurance personnel can thus have programs ready to measure the part as soon as the prototype is complete. In many quarters, offline programming is slashing days from product-development cycles. Of course, vision systems can only measure what the camera can see. So, when something obstructs the camera s view of a feature another type of probe is necessary. In the past, this might require removing the part from the vision system and using a different measurement device. In contrast, the software used in advanced, multi-sensor systems lets users collect data using a combination of cameras and other probing technologies on the same machine. In the medical industry, the most common alternatives are touch-trigger probes and white-light sensors. Sophisticated calibration techniques consolidate the measurements coming from these sensors into a single coordinate system. It makes no difference which type of probe collects the data. In addition, rotary and trundle tables make it possible to present the part to any sensor at an optimal orientation for accurate measurement.

13 Software 13 An eye for quality Vision and multisensor inspection is one of the most exciting and fastest growing segments of the metrology marketplace. The reason for this is quite simple. Fast microprocessors and advanced CAD-software have combined to bring vision and multi-sensor measurement capabilities and their advantages into the mainstream of manufacturing. It wasn t so long ago that vision systems would be tucked away at the back of specialist labs, but today they are finding their way into all types of industrial measurement environments. So what are the advantages of a vision system equipped with PC-DMIS Vision? PC-DMIS Vision is based on the same architecture as PC DMIS CMM, therefore people who already know how to use CAD-based CMM programming can learn how to program a vision or multi-sensor system with only a little additional training. By utilizing CAD the time spent developing inspection programs can be reduced by up to 75% over more traditional methods. PC-DMIS was the first CMM software to integrate CAD into the measurement process. It has a sophisticated set of tools crafted to ease the job of developing, debugging and executing measurement programs. For PC-DMIS Vision the software has taken these capabilities and added powerful new ones to meet the unique requirements of vision metrology. and the Chromatic white light sensor (CWS). Thankfully PC-DMIS Vision supports a wide range of multi-sensor configurations seamlessly. Users can quickly and easily cross calibrate sensors and then use them interchangeably within their measurement programs as needed. In addition vision sensors fitted to conventional CMMs are also supported. EdgeDetector Identifying the edges of features of interest has always been a difficult issue for vision inspectors. Users had to understand how to manually apply a selection of filters to find edges that might be unclear to the camera even though they are clearly visible to the naked eye. PC-DMIS Vision answers this issue with a number of advanced edge detection algorithms. Vision and multisensor measurement is no longer too specialized or difficult for the average user to consider. So if you have inspection problems with parts that may be easily damaged or distorted, features to small or not accessible to touch probes then you may be ready for the advancements that a vision and multisensor software like PC-DMIS Vision will give you. PC-DMIS Vision is available both as original equipment and as a retrofit for a wide range of other vision measurement systems. MultiCapture is a revolutionary vision measurement technology that automatically finds multiple features that fit within the same field of view and captures their measurement data simultaneously. Upon completing the measurements in a particular field of view, MultiCapture drives the camera to the next cluster of features and measures them in the same way. This sequence continues until the inspection program is complete. Multiple feature types such as holes, slots and edges can all be measured in the same shot. This feature alone can improve program cycles by 35% or more! Camera Simulation PC-DMIS Vision s CAD Camera allows users to accurately simulate part execution on a CAD model. It accurately simulates selected measurement options including, camera views, lighting and probe selection. It works either on-line or off-line and has the unique capability to reproduce precisely what the camera will see as it measures a part. When simulating program execution, programmers can switch between a CAD view and a virtual camera view, which changes in step with the inspection program. Multi-Sensor Capable Today s vision systems don t just come with a camera, models can include optional touch probes, scanning probes, Through-The-Len Laser (TTL Laser)

16 16 Case Study The multisensor system can inspect 30 to 40 implants in one session using pallets. Optical and tactile sensors tackle this implant. Screw holes and external radii have to be measured along with flatness and fit.

17 Case Study 17 Hitega Präzisionsmechanik Watertight records Measuring a component for the semiconductor industry using a laser sensor. Precise, compact and somewhat special. The perfect description of a Hitega product. The company from Gangkofen in Lower Bavaria has established itself as a precision engineering service provider. Various optical, tactile and multisensor measuring systems are essential to the success of the Hitega team. Not without good reason, the company has invested in top-class measuring equipment: In particular, its customers in the healthcare and biomedical engineering sectors require 100% inspections and watertight, fully comprehensive documentation of every single stage of the process. Precision is our passion. Such is the company s claim. That is obvious when taken on a tour of the company. Kaizen charts everywhere. A spotlessly clean production hall. Shiny machining centres representing the state-of-the-art, as far as the eye can see. At Hitega we work in a field of absolute precision, says Managing Director Michael Herre. We have made a name for ourselves in the single and small batch part production of high-precision machined components, prototype construction, assembly and fabrication engineering mainly for the biomedical engineering, semiconductor and appliance industries. Materials such as aluminium, stainless steel, technical plastics and magnesium are processed at Gangkofen. Hitega relies completely on its know-how in the fields of assembly and metrology. As the focus is on assembly and the associated metrology, Hitega has invested strongly in these areas, particularly in its equipment and employee training. Metrology is part of our core business, says Herre. Three multisensor systems supplied by Hexagon Metrology are used for quality assurance at Hitega. Two of the systems have a measurement range of 400 x 400 x 200 mm, the third handles a measurement volume of 600 x 600 x 200 mm. Armed only with callipers and a micrometer, Hitega would not have progressed very far. The parts are too complex and the requirements of the customers too high. Flexible multisensor technology Martin Ebner, production manager at Hitega, explains: Everything has become increasingly complex over recent years. We receive parts, for example spinal implants, which have form and position tolerances here, there and everywhere, all of which have to be checked. With one of these implants, we have to deal with form and position tolerances on three holes using the maximum material principle relat-

18 18 Case Study ed to three datums. Screws are inserted into these holes later to attach the implant to the bone structure. Tolerances on the various features are usually of the order of hundredths of a millimetre and in most cases are checked against the CAD model. Hitega employs optical and tactile measurement procedures in order to capture all the features. By using multisensor measuring systems from Hexagon Metrology, Hitega can do all this in one clamping operation. All three machines are fitted with high-precision optical and tactile probe systems as well as laser sensors. Traceability from A to Z However, multisensor machines on their own are not enough. Just as important is complete documentation. The vision software package from Hexagon Metrology allows the user to inspect and document all the functionally relevant features on every single object. Depending on the customer s requirements, Hitega Präzisionsmechanik can produce documentation in electronic or paper form, or a combination of the two methods. For some of Hitega s customers, the US-American Food and Drug Administration (FDA) regulations come into play. The FDA s CFR 21 Part 11 covers electronic records and signatures and is mandatory for manufacturers of biomedical engineering products. It seeks to ensure that all production process records are safe from manipulation. Our new Optiv Performance 442 supplied by Hexagon Metrology is equipped with a suitable validation program. It allows us, for example, to maintain the passwords of each user in a protected database, record user access to the system and assign everyone with an electronic signature, explains Ebner. Traceability is the magic word in biomedical engineering and healthcare. Almost like measuring it yourself The importance of the validation system becomes even more apparent with one look at the measuring strategies at Hitega Präzisionsmechanik. In the case of small batches with a high metrology content, in other words, parts with close measuring intervals and many features to be measured, the company opts for inspection by the production staff. Martin Ebner sets up the measuring program to cope with this: I have designed the user management system to allow certain operatives limited user rights for certain parts. The operative enters his name, password and the ID number of the part. The monitor then displays an image showing the operative exactly how he has to clamp the part. With just a few mouse clicks, he can start the measuring program, which then runs fully automatically. For larger batches, Hitega switches to pallet measurement. Two of the multisensor measuring systems from Hexagon Metrology are configured to do this. Spinal implants manufactured from PEEK (polyetheretherketone) are some of the products inspected like this. The multisensor system completes a 100% inspection of 30 to 40 implants overnight without user intervention. Capacity bonus thanks to offline programming Inspections by the production staff. Pallet measurement. Sometimes there is hardly any machine time left for measurement programming. A good reason for Hitega to invest in an offline programming station. Swapping programs between machines is no problem, as all three multisensor measuring systems have the same Vision software from Hexagon Metrology installed. About 70% of the programming is purely data input, for example loop programming or parameter assignment. The offline station has proved ideal for this sort of task. Previously we had only one Hexagon Metrology measuring machine with multisensor capability, with which we performed intermediate checks, final inspections and programming. Now of course, we have a much better arrangement, says Martin Ebner. And his satisfaction with Hexagon Metrology software support is clear: The software itself is superb and the support from Hexagon Metrology is top class. Over all this time we have found Hexagon Metrology willing to listen and quick to come up with a solution. The measuring concept based on operator self-inspections, pallet measurements and offline programming is gaining in popularity. Hexagon Metrology provides the tools for this strategy: flexible and accurate multisensor systems that inspect and document, while keeping your records absolutely watertight.
