ATOS Capsule – Optical Precision Measuring Machine for Quality Assurance with Highest Image Resolution

GOM GmbH, based in Braunschweig, Germany, is expanding its ATOS series by a new sensor for full-field digitizing and inspection of contoured part geometries.

The fringe projection system is used for production quality assurance of small to medium-sized parts and excels by its high precision for fine details. ATOS Capsule is used, for example, for first article inspection of gears, turbine blades and wheels as well as medical parts. In addition to surface deviations from CAD, GD&T data and detailed information is derived automatically.
ATOS 3D scanners have become firmly established in optical metrology. ATOS Capsule combines proven GOM technologies, such as Blue Light Technology and the triple scan principle, with a cutting-edge housing design that provides optimum protection against dust and splashing water for industrial use. Due to the maximum stiffness of the unibody housing, the sensor achieves the required process stability for automated applications and precise measuring results.
In the standardized measuring machine ATOS ScanBox, the ATOS Capsule system is used for fully automated measurements and inspection. The ATOS ScanBox is a complete optical 3D measuring machine that was developed by GOM for an efficient quality control in production and manufacturing processes. For different part sizes and applications, flexible and partly mobile solutions are available. Using the photogrammetric add-on sensor ATOS Plus, bigger components or several parts can be measured simultaneously in an ATOS ScanBox, while increasing the overall accuracy at the same time.
Two versions of the ATOS Capsule are available with different levels of detail. The system captures 8 or 12 million points per scan with changeable measuring areas. The dimensions of the sensor, its low weight and the short working distance simplify its application in practice.

Renishaw unveils the new XM-60 multi-axis calibrator

Renishaw, the world-leading metrology specialist, exhibited its new XM-60 multi-axis calibrator at IMTS 2016, Chicago, USA and AMB 2016, Stuttgart, Germany. The XM-60 is capable of measuring all six degrees of freedom from a single set-up, in any orientation for linear axes. It offers significant improvement in simplicity and time saving over conventional laser measurement techniques.

As demands on component tolerances increase, manufacturers are now required to consider all error sources from the machines producing parts; angular errors as well as linear and straightness errors. XM-60 captures all these errors in a single set-up. Designed for the machine tool market, the XM-60 multi-axis calibrator complements Renishaw’s calibration product line which includes the XL-80 laser system, XR20-W rotary axis calibrator and QC20-W wireless ballbar. The XM-60 uses the XC-80 environmental compensator to correct for environmental conditions.

The XM-60 multi-axis calibrator provides a highly accurate laser system that incorporates unique technology with a patented optical roll measurement and fibre optic launch system. The compact launch unit is remote from the laser unit, reducing heat effects at the point of measurement. It can be mounted directly to the machine on its side, upside down and even on its back, which is particularly beneficial in areas with difficult machine access.

Reducing uncertainties of measurement is paramount for any user. The Renishaw XM-60 has been designed to measure machine errors directly, reducing the inaccuracies which can result from complex mathematics used in some alternative measurement techniques. Direct measurement makes comparison before and after machine adjustments a quick and simple task with users’ existing part programs for XL-80 measurement. The receiver is fully wireless and powered by rechargeable batteries, avoiding trailing cables during machine moves which could cause inaccuracies or break the laser beam during measurement.

The performance of each XM-60 multi-axis calibrator is traceable to international standards and every unit is also certified before shipment. This provides users with the confidence that their system will deliver the specified accuracy day-after-day where it counts – in the workplace.

To support the release of the XM-60 multi-axis calibrator, a new version of Renishaw’s CARTO software suite will be released to guide users through the workflow of the measurement process.

XL-80 laser functionality extended to perform diagonal tests

Renishaw launched a Linear diagonal measurement kit at EMO 2015. Laser diagonal tests can be used to measure diagonal positioning and reversal errors in accordance with B5.54 and ISO 230-6 standards. The ISO 230-6 standard states that diagonal displacement tests allow the estimation of the volumetric performance of a machine tool. The new kit is quick and easy to set-up, is easy to align and allows fast data analysis to international standards.

The Renishaw Linear diagonal measurement kit provides everything needed to perform laser diagonal tests with an XL-80 laser interferometer system. The kit is designed for quick and easy set-up, with purpose-built fixturing that’s magnetically mounted to the machine tool bed and holds the XL-80 and optical accessories. A beam steerer and swivel mirror (attached to the plate) then provide a very controllable way to align the laser beam with the machine diagonals.

A key advantage of using the new kit to mount the XL-80 and optical accessories on the machine bed is that after measuring one machine diagonal, the plate can be moved to the other body and face diagonals with easy realignment.

As well as the hardware system, Renishaw also provides software to easily carry out laser diagonal tests. XCal-View provides convenient data analysis for laser diagonal tests, in accordance with ISO 230-6 and B5.54 standards. The application can take the data from laser diagonal tests and provide a report that shows the key errors and gives a graphical display of the results.

Manufacturers using the Renishaw Equator™ flexible gauge now have even more options for inspecting parts right where they are being made – on the shop floor, in the toughest of conditions. With the new TP20 touch trigger probe kit, Feature Compare and updated EZ-IO software, flexible gauging is now ultra-fast, simpler to setup and easier to automate.

Flexibility
Equator gauges are already used by hundreds of manufacturers worldwide for high speed flexible gauging, as manually loaded systems or in fully automated cells. Equator provides flexibility for engineers to re-program for design changes and for shop-floor operators to switch between different parts in seconds, using repeatable removable fixture plates and easy-to-use Organiser software. Manufacturers recognise the benefits of Equator’s combination of flexibility, fast scanning, low purchase price, and low cost of ownership (Equator requires no regular re-calibration). These benefits, when combined with the system’s unique ability to compensate for the effects of challenging environmental conditions, make it the gauge of choice in any industry.

Short cycle times for all applications
The ultra-fast TP20 touch trigger probe can now be combined on Equator with the high speed scanning of the SP25 scanning probe. TP20 can be used for fast capture of discrete point data, with the stiff lightweight structure of Equator allowing very short cycle times and high repeatability on simple touch point measurements. The touch trigger kit includes robust industry-standard TP20 modules and a new range of extension bars and joints.

Feature Compare
Equator uses the principle of mastering to cope with changes in temperature on the shop floor. Now the process of calibrating the master part is made very easy with the new Feature Compare function. Master parts do not need to be expensive or custom made; users can simply take a production part and measure it. The master part could be measured in a number of ways, including on a calibrated co-ordinate measuring machine (CMM) in a temperature-controlled environment. This measurement establishes the variation of the master part from CAD or drawing nominals. With Feature Compare the user can simply take the master part measurement data and enter the compensation values for each feature’s size, position or orientation. The simple and unique Feature Compare interface has been designed for effortless data input.

There are much more to discover. For further information on Equator gauging visit www.renishaw.com/gauging.

To extend competitive edge

Advanced CNC systems from NUM are helping US machine tool manufacturer Bourn & Koch, Inc. to extend its competitive edge in the market by using state-of-the art machine control software. Following a highly successful project to migrate control of powerful 7-axis horizontal gear hobbers to NUM’s Flexium CNC platform, the company is now standardising on this control technology for an extensive range of its gear production machines.

All seven axes on the 400H Series II gear hobber, including the 560 Nm work piece spindle motor, are controlled by NUMDrive C servo drives and a Flexium 68 CNC system.
All seven axes on the 400H Series II gear hobber, including the 560 Nm work piece spindle motor, are controlled by NUMDrive C servo drives and a Flexium 68 CNC system.

Bourn & Koch chose to upgrade to NUM’s Flexium CNC on its 25H – 400H Series II gear hobbers, starting with the 400H. The speed and power of this machine means that it can replace as many as seven older style gear production machines, making it a popular choice with companies machining large precision components such as bull and cluster gears, worms, shafts, splines and pinions. Capable of accommodating work pieces up to 400 mm (16 in) in diameter, the 400H has an axial travel capability of 1,168 mm (46 inch) as standard and can be customised for the production of even longer parts. Customers are typically prime and sub-contract manufacturers producing mechanical power transmission components and systems for the defence and aerospace, oil/gas drilling, mining, heavy equipment and power generation industries.

To simply program the machine
The HMI on the 400H gear hobber makes full use of the software’s capabilities by combining a conversational style dialogue with powerful graphics, which means that the machine operator does not have to use or even know about ISO languages. To produce a part, the operator simply inputs machine setup information such as cutting speeds, work piece and tooling geometry via simple fill-in-the-blanks menus, while graphical images provide clear and unambiguous views of the hob tool and resultant gear part. All calculations involved in creating the machine control program for a particular part are handled completely automatically.

The company decided to migrate the design to NUM’s Flexium CNC platform as a matter of course. Tim Helle, President of Bourn & Koch, explains, “We offer customers a choice of CNC – NUM is the standard on most of our gear hobbers – and have a policy of using the latest technology to maximise the performance and cost-effectiveness of our machines. This approach also results in progressively simpler machine operation, with less need for training, and means that spares are readily available, which contributes to machine uptime and reduces customers’ support costs.”

Bourn & Koch now offers NUM’s Flexium CNC on its powerful 400H Series II 7-axis horizontal gear hobbing machine and intends standardising on this control technology for many existing and new designs.

Clamping force gauge Testit, clamping force measurement over machine control

The Siemens Sinumerik CNC controllers have been getting the maximum productivity out of each machine for over 50 years. Now they have another partner on their side: the Hainbuch Testit software. It is available on a data carrier for installation on Siemens CNC controllers [Sinumerik 840 D sl plus PCU50]. This means that a separate laptop is not needed anymore and manufacturing with “theoretical clamping forces” is also a thing of the past.

The clamping force measuring device increases productivity through precise clamping force measurements.
The clamping force measuring device increases productivity through precise clamping force measurements.

Thanks to Testit, the operator always knows which clamping forces exist and where, and the actual maintenance status of the clamping device. And given the safety standard DIN EN 1550, it is a “must have”. This means: The Testit clamping force gauge together with the Siemens CNC controller executes a target-actual comparison of the maintenance status of a clamping device. If the limit values are underranged, a warning message is output. Perfect, don’t you think?

Safe results – even with mandrels
The globalization of markets requires an optimum of the machining process. Those who face stiff competition can no longer afford to manufacture just by “feeling”. Measurement data is demanded! It not only functions perfectly for outer diameters and during rotation, it also precisely measures the holding force of mandrels for inner diameters.

Key advantages:
Clamping force measurement for O.D. and I.D. clamping
Can be used rotating and for stationary applications
Direct input onto the Siemens CNC controller
