BUSINESS – PRODUCTS MEASUREMENT Mitutoyo micrometer
Metrology specialist, Mitutoyo, has announced the release of what it claims to be the world’s first micrometer to offer 0.1µm resolution measurement. The unit utilises the company’s patent pending absolute rotary sensor, manufactured utilising their own high precision screw machining technology. This sensor reduces instrument error to ±0.5µm to deliver accuracy with no trade off in operability. The system also eliminates the need to re-set the origin each time power is turned on, enabling measurements to be taken immediately upon start up.
SOFTWARE
Geomagic reverse engineering solutions
Geomagic, a developer of 3D software for creating and inspecting digital models of physical objects, has launched a new version of its Geomagic Studio software system. Geomagic Studio 2012 can transform scans of physical objects into precise 3D models and deliver this data into polygon, surface and CAD models for use directly in reverse engineering, product design, art, rapid prototyping and analysis. The data can also be transferred directly from Geomagic Studio as history-based parametric models into popular MCAD systems. The new programme delivers
a robust user interface that delivers simplified commands for complex processes, as well as precise surfacing, powerful
automated point cloud data clean-up and rapid surface repair of models. It has been enhanced to deliver better sketching and patching tools, a new scripting environment for automation of functions at the command level and improved handling and viewing of mid to large-range data. Geomagic Studio supports direct output of 3D parametric data into major MCAD platforms, including Autodesk Inventor, SolidWorks, CATIA and Creo Elements/Pro (formerly Pro/ Engineer). See

EDM (electronic discharge machining) machinery specialist, AgieCharmilles, has recently introduced its new Integrated Vision Unit (IVU) to provide optical measurement of EDM- machined details that a 3D probe cannot deliver. With this technology, the company says it is possible to visualise and measure components directly on the machine tool and correct machining errors. EDM is often used for the manufacture of intricate parts with very close tolerances, which the IVU system allows careful measurement of. The IVU allows for accurate manufacture of highly detailed parts, and tooling for the production of electronic components, to very fine tolerances. The company
recommends the IVU to complement its CUT 1000 EDM machine, with the unit allowing for faster and more accurate set up for machining operations, with high accuracy measuring cycles available for edges, part alignment and centring – all to micron accuracy. The IVU’s charge-coupled
device (CCD) camera produces clear images, even in less than ideal lighting conditions. Fixed on the machine’s upper head and with a backlight installed on the lower head, the camera’s autofocus provides images that are analysed by dedicated software to deliver the metrology information required, while also allowing for visual inspection.

In addition, the measurement origin can be pre-set to any value within the display range to reduce set-up time and improve repeatability. The display can be zeroed at any position, making comparison measurement easier. Display resolution can
be switched to 0.5µm if 0.1µm measurement is not required. Additionally, the micrometer supports output to measurement data applications such as MeasurLink, Mitutoyo’s proprietary statistical processing and process control programme, which performs statistical analysis and provides real-time display of measurement results for SPC applications.

MACHINE TOOLS DMG 85FD machining centre
Machine tool manufacturer, DMG, has released its new DMU85FD, a compact universal machining centre that is capable of both turning and complex milling operations in a single set up. Maximum table load capacity is 1000kg and maximum workpiece dimensions are 850mm diameter by 590mm. Maximum table rotational speed is up 800rpm, while stability and dynamics in the tandem drive version allow an additional 40rpm in the swivel axis. The DMU 85FD has an 18,000rpm, 35kW spindle and an HSK-A63 tool interface.

An HSK-H100 spindle option delivers 44kW / 288Nm torque. The FD also incorporates special mill-turning cycles to facilitate single set up operation. These include automatic checking and correction of imbalances, automatically varied rotational speeds to avoid component vibration and swivelling of long tools into the workpiece. Mill-turning cycles such as piercing, undercutting or multi-blade tool usage are available by default to assist maximum productivity. See
