New CEO at Anca

Dr Christopher Hegarty will be appointed CEO at tool and cutter grinder specialist Anca group from 1 July 2018, succeeding Grant Anderson.

After eight years in the role at Anca, Anderson will retire at the end of June. Hegarty joined the Anca group from Switzerland in July 2017 as the engineering manager of CNC machines, and more recently as general manager of that division. He has also worked at machine tool manufacturers in Europe and Australasia, including over 15 years as CEO or general manager in other organisations.

Laser measurement in control

A new laser-measuring system was given its UK debut at MACH 2018 last month and is promising to reduce the time taken to measure cutting tools by 60%. Blum-Novotest, which says it has 95% of the global machine tool market for this technology, provided live demonstrations of the LC50, the next generation of the laser and latest addition to the Digilog family.

The LC50 was fitted to a Fanuc Robodrill on the company’s stand, where visitors were able to witness how the laser optics, new-design shutter protection system and HPC nozzle provide in-machine measurement data. Blum Novotest expects the new product to generate over £500,000 of new orders over the next two years, with the main interest coming from manufacturers supplying high value parts to the automotive, motorsport and aerospace sectors.
“By evaluating the analogue signal rather than the digital one, we can take thousands of measuring values of all cutting tool edges every second, resulting in highly dynamic measurement of tool parameters,” explains managing director David Mold. “In essence, this technology is 60% quicker than conventional in-machine measuring. Even the coolant influence is bypassed by automatically filtering out dirt
and coolant residue on the tool.
“The LC50 is targeted at customers who really need to control the whole machining process and want to implement Industry 4.0 standards in their manufacturing operations as it allows them to control the variables of cutting tool, workpiece and temperature.”

Laser projector optimises manufacturing

The TracerM laser projector from Faro Technologies enables users to perform positioning, alignment and assembly tasks, quickly, accurately and safely.

Faro’s TracerM projects a laser on to a surface or 3D object, providing a virtual template that allows companies to improve productivity, reduce waste and eliminate rework. The laser template is created using a 3-D CAD model that facilitates the projection of a detailed laser contour of components or areas of interest, removing the need for physical templates and tools, and reducing the potential for human error.
TracerM provides long-range projection from 1.8 to 15.2 m. The device includes Faro’s Advanced Trajectory Control (ATC) function, which ensures fast projection with dynamic accuracy and a rapid refresh rate, minimising the ‘flicker’ associated with other systems.
Faro’s 3D laser projector can also be used in series for use on large assemblies; multiple TracerM devices can be controlled from a single workstation to provide a virtual template in a single (or shared) co-ordinate system.

3D scanning CMM introduced

Creaform, which is represented in the UK by Measurement Solutions, has launched the Cube-R automated dimensional inspection solution.

This optical 3D measuring machine utilises the Creaform MetraScan 3D-R metrology scanner for parts ranging from 1 to 3 m in size. The company says that Cube-R delivers both speed and volumetric accuracy, offering a realistic and comprehensive alternative to CMMs and other robot-mounted, structured-light 3D scanners.
According to Creaform, Cube-R can inspect several hundred parts a day, even on dark or reflective parts with complex geometry. Importantly, the machine offers simultaneous operation of data acquisition and analysis as part of a continuous and uninterrupted measurement flow. There is said to be no accuracy drift over time.
“Quality control managers are looking for integrated solutions that enable the detection of assembly problems earlier in the manufacturing process, all while reducing waste and downtime to ensure better productivity and higher product quality,” says Jérôme-Alexandre Lavoie, product manager at Creaform. “The Cube-R was designed with that in mind. It is the latest addition to our R-Series automated inspection solutions, which also include technology integration for clients seeking customised dimensional measurement solutions.”

CT for process control in AM

Metal additive manufacturing (AM) company Sintavia has installed a Nikon Metrology computed tomography (CT) system at its facility in Florida, US to help control the AM process.

Using powder-bed AM with electron and laser-beam melting, Sintavia currently manufactures components from Inconel 718 and 625, aluminium, titanium, cobalt-chrome, stainless steel and other proprietary powders.
AM allows special internal designs to be realised, such as conformal cooling channels, lattice networks, hollow members and other complex geometries. Both additive and traditional manufacturing can result in microscopic voids and gaps within the structure, which can cause stress fractures and reduce the longevity of a component’s lifecycle. All of these internal features can only be inspected non-destructively with CT scanning.
Sintavia has installed a 450 kVA micro-focus CT (micro-CT) system from Nikon Metrology. By converting 2D pixels to 3D voxels, supplying a full 3D density map of the samples, the technique presents information in a visual, easy-to-interpret format and shows any departure from the CAD model. It is said to be straightforward to detect and measure powder residues blocking channels, porosity, contamination, cracking, warping, and dimensions such as wall thickness to an accuracy within tens of microns. Given a 100 mm sample and a detector 2000 pixels across, the limiting resolution would be 50 µm, for example.
Micro CT is now much faster and more suitable for production-line use, while CT scanning of similar parts can be automated using loading and unloading equipment. Scan times down to a few tens of seconds per part are possible.
