Automated CMM stylus cleaning

After detailed research into the effects of stylus-tip contamination when using a CMM, Dr Simon Lawes, Manufacturing Metrology Team at the University of Nottingham, said: “A stylus tip contaminated with tiny particles can lead to measurement errors 10 times greater than expected.” The problem in inspection rooms and on the shop floor is that stylus cleaning is a tedious and time-consuming job that reduces the amount of time the CMM is available for measuring.

To alleviate the problem, UK-based CMM manufacturer LK Metrology has introduced an automated stylus-tip cleaning system, LK StyliCleaner. It takes just 30 seconds to remove debris from a stylus tip, eliminating the tendency to delay cleaning and reducing the risk of taking inaccurate measurements.

LK says that the cleaning system is an inexpensive solution and works with all brands of CMM and software. No software integration is needed, just a simple part program for controlling the cycle. For LK CAMIO customers, the StyliCleaner is bundled with free-of-charge part programs for automated stylus-tip cleaning.

Controlled by the CMM’s axis movements, the automated cleansing cycle activates when a dirty stylus is programmed to move in front of the StyliCleaner motion sensor.

LK’s compact StyliCleaner, which has a 70 x 100 mm footprint, is available in two sizes, StyliCleaner8 and StyliCleaner16, to decontaminate styli from 0 to 8 mm, and from 6 to 16 mm in diameter. The separate control unit may sit on the CMM table or, if space is limited, can attach to the CMM stand via an optional mounting plate.

GM CNC expands team

Unprecedented growth at GM CNC has seen the machine-tool specialist expand its team with two new recruits. The latest marketing appointments will see the company further build brand awareness, social media interaction, and provide support to the sales and service teams. Jake Riley and Reece Mundy will work across GM CNC and sister company GM Machinery, building communication platforms with existing and potential customers to inform the manufacturing industry about products, offers, services and live machine-tool auctions and events.

GM CNC director Nicola Howard says: “Digital marketing communication is an industry within itself, and while most companies believe they are proficient because they have LinkedIn or Facebook accounts, this route to market is vitally important to communicate with existing and new customers. This is why GM CNC is convinced that digital marketing communication deserves the attention of dedicated and experienced team members.”

15% lighter landing gear

Safran Landing Systems, the world’s largest supplier of landing gear, has teamed up with German metal additive manufacturing (AM) equipment specialist SLM Solutions to evaluate the feasibility of using its technology in the production of large, safety-critical aircraft components.

The trial involved 3D-printing the main fitting for the nose landing gear of a business jet, layer-by-layer, from titanium alloy powder.

It was a world first for such a large part measuring 455 x 295 x 805 mm tall. The component was redesigned to optimise its production using metal powder bed AM, leading to a time saving in the build process and a significant weight reduction of around 15% in comparison with milling the part from a forging. SLM Solutions’ sole agent in the UK and Ireland is Kingsbury.

Hainbuch expands clamping portfolio

With the acquisition of Vischer & Bolli Automation in Lindau, Hainbuch is expanding its range of stationary workpiece clamping devices. As a result of the purchase, Hainbuch is able to offer custom solutions for workpieces of up to 100 tonnes, or 10 to 20 m in length. The zero-point clamping system screws on to the machine table, serving as a base for fast changeovers. Both pneumatic and hydraulic versions are available for either manual or automated solutions.

To clamp the workpiece on the base, a vice, clamping tower, modular clamping device or magnetic clamping plate can be used depending on requirements, thus ensuring an optimal and economic solution is available for every workpiece, regardless of shape or size.

Wireless multi-sensor laser scanner

Hexagon’s Manufacturing Intelligence division has launched a wireless multi-sensor laser scanner with metrology levels of precision for operation inside CNC machine tools. The m&h LS-R-4.8 can capture around 40,000 measurement points a second and securely transmits the data to a receiver, via radio, enabling operators to change the sensor automatically without manual intervention.

Measuring on the machine tool, whether for workpiece inspection, temperature or tool control, is a valuable source of information in the machining process. With this data, it is possible to control workpieces before, or even between, machining operations. The wireless scanner will remove bottlenecks by taking in-line measurement for in-process enhancements away from CMM machines.

Capturing 40,000 measurement points a second provides information about the complete part, rather than selected individual points. This capability enables users to evaluate production quality, enhance manufacturing processes by identifying problems early, better align parts for steps later in the workflow, and gain an insight into complete part quality.

Notably, the wireless scanner deploys laser triangulation to deliver high levels of speed and accuracy. The laser beam projects on to the component and its reflection passes through a lens for detection by an imager. That information then determines the positional measurement points.

Dedicated modular software presents the data in an easy-to-understand format, making it simple for machine operators or quality teams to quickly identify issues and correctly align a part for reworking while it remains in the machine tool.

Hexagon’s new package includes the wireless scanner, modular software and the company’s RC-R-100 multi-sensor receiver. The scanner is stored directly in the machine’s tool magazine, from where it inserts automatically into the spindle without manual intervention.
