Plug in, automated, non-contact measurement for cobots

The UK’s only fully traceable, automated non-contact gauging system is now available from RARUK Automation. Introduced as a plug and play accessory for the company’s e-Series range Universal Robot six-axis collaborative robot (cobot) arms, the Vectro-2 is the brainchild of Third Dimension, a company with a long track record of supplying non-contact optical measurement systems.

Vectro 2 enables automated 2D profile measurements to be taken quickly and accurately. The kit contains all the pre-configured hardware and software required for easy installation and rapid deployment. Measurement data can be used for inspection and quality control purposes or fed back to the production process for closed-loop control to minimise defects and waste.

The system can measure a variety of parameters: gap and flush, edge, radius, chamfer, angle and many other critical features in the manufacturing process. Thanks to the violet laser technology used in the Vectro 2’s new T-series sensor heads, it can be used on challenging surfaces such as high-gloss paint, glass, plastics, bare metal and fabrics.
RARUK Automation is the only UK distributor to hold platinum status, achieved through the depth of its technical expertise in identifying applications that can be successfully automated. The addition of Vectro 2 to its portfolio, significantly widens the scope of this work.

Through easy graphical programming, Vectro 2 makes it easy to create powerful, data-driven inspection and measurement processes that improve productivity. And, in line with all automation systems from RARUK Automation, Vectro 2 is system that can be applied in any manufacturing environment, from small start-ups to volume production.

RARUK Automation and Vectro 2 can be seen later this week at the North East Automotive Expo 2022 (stand B29) on 29 September at the Beacon of Light, Sunderland.

How to benefit from subcontract measurement

Following assembly, manufacturers must measure parts to ensure they meet specification. However, if they only have one CMM, or they measure parts by hand using micrometers, manufacturers will do so at a much slower rate, significantly delaying time-to-market. Furthermore, measuring any component manually not only slows down production, it also introduces the risk of human error.

While investing in more measurement equipment could be a simple solution to removing any bottlenecks, it might not be the most practical option. As well as the initial cost of the machine, manufacturers must invest in training to ensure that they can use the equipment correctly. Smaller manufacturers may not be able to buy equipment outright, so instead they can look to subcontract measurement services.

By working with a metrology specialist such as The Sempre Group, manufacturers can have peace of mind that someone else is measuring their parts accurately. Metrology engineers can take information from drawings and CAD files to determine the method of measurements and which machines to use. To measure complex parts, subcontract measurement experts can develop bespoke fixtures to hold parts steady. Once the customer agrees to the quote, engineers will measure a small batch of parts, sending reports back to the customer to verify they have met expectations. Following verification, engineers will measure the rest of the components, deliver reports and send the parts back.

Instead of relying on one trained engineer and one in-house CMM, manufacturers can take the pressure off and speed up production by outsourcing measurement to dedicated experts.

CMM enables most accurate Lotus car ever

Since the first Lotus car was built in 1948, the company has been a beacon in the automotive industry for the design and manufacture of high-performance cars born out of success on the racetrack. The latest sports car, the Emira, is by far the most accurate model ever built by Lotus thanks to an upgrade in quality control at the company’s factory in Hethel, Norfolk. The upgrade includes investment in a five-axis HC-90TR twin-arm CMM manufactured in the UK by LK Metrology. This automated, multi-sensor inspection cell, part of multi-million pound investments made by Lotus since 2017, delivers absolute, 100%, non-contact dimensional inspection at production line speed, enabling real-time quality control.

The CMM is set 1 m into the floor on a special foundation. This configuration means that a car for inspection carried on an automated guided vehicle (AGV) can access the area without the need for any lifting equipment. The machine has a measuring volume of nominally 6.3 x 1.6 x 2.5 m, easily large enough to contain an entire car body.

Triple-laser cross scanners are deployed on both arms to measure features automatically on both sides of the Lotus Emira simultaneously. LK says that the HC-90 is the world’s most accurate range of horizontal-arm CMMs, able to measure to a volumetric accuracy of 10.0 μm + L/200 and with 6 μm repeatability. The machine combines the high performance of a bridge-type CMM with the flexibility of the horizontal-arm configuration widely used in car plants.

The CMM completes automated measuring cycles so quickly that it can keep up with the quick TAKT time that defines the speed of the Emira production line.

Recognition for apprentices

An advanced engineering and manufacturing apprentice from Telford was named as the region’s brightest vocational star last week. Torus Measurement Systems’ James Morgan overcame competition from more than 100 apprentices across the West Midlands to secure the ‘Outstanding Learner of the Year’ title at this year’s annual In-Comm Training Awards in Birmingham. The high-profile ceremony, which is backed by main sponsor the Engineering Technology Group (ETG), saw ‘girl power’ come to the fore again, with four out of the eight personal accolades won by females.

MTC apprentices reach for the skies2

High-flying apprentices studying at MTC Training – the training arm of the Manufacturing Technology Centre – are getting the chance to build major components for an airworthy light aircraft in an initiative to give them valuable manufacturing experience. The apprentice team is celebrating after completing the first stage of the project – a critical structure for the left wing. They now plan to have both left and right wing assemblies complete over the coming weeks, along with the aircraft’s fuel tanks. Supported by the Department for Transport, Project Slingshot will result in the manufacture of an airworthy Sling 2 aircraft.
