Virtual work experience provides inspiration

Renishaw is running a virtual UK work experience programme in 2021. The company will virtually host 140 students in years 10 to 13 with week-long sessions during school holidays from mid-February until the end of July. These sessions will provide students with exposure to a wide range of engineering disciplines, such as design, development and manufacturing, to encourage young people into STEM (science, technology, engineering and mathematics) careers. Renishaw’s work experience schemes are project-based to give students an insight into a career
in engineering.

High productivity and long tool life

Kennametal has expanded its HARVI I TE series with the HARVI I TE four-flute ball-nose end mill. Designed for productive 3D roughing and finishing operations, the new cutter delivers lower machining cost through maximum metal removal in a broad range of materials, says the company.

The HARVI I TE ball-nose end mill features a novel proprietary relief that requires a closer look. In the most critical area – the ball-nose section – a wavy contour shapes the rippled relief that provides improved coolant flow into the cutting zone. The result, according to Kennametal, is maximised productivity and tool life in 3D milling operations.
In addition, the rippled relief enables higher feeds and speeds, as well increased depths of cut, thanks largely to advanced vibration damping and lower cutting forces.

On the outer diameter, the relief changes its shape, and turns into the eccentric faceted relief. Kennametal says this eccentric faceted relief provides exceptional edge strength, geometric accuracy, lower cutting forces and makes the HARVI I TE four-flute ball-nose end mill highly versatile.

Further geometry advancements of the square-end styles – including a twisted end face, chip gashing and a variable helix angle – also feature in this new solid-carbide end mill.

Kennametal is making the HARVI I TE ball-nose end mill available in two different lengths, both with a diameter range from 2 to 20 mm.

Boeing and AMRC renew partnership

Boeing has renewed its long-standing relationship with the University of Sheffield’s Advanced Manufacturing Research Centre (AMRC). The tier-one partnership agreement will continue two decades of innovation and collaboration for another five years, extending Boeing’s access to the R&D capabilities of the AMRC.

“Renewing Boeing’s partnership with the AMRC demonstrates our commitment to Sheffield and showcases what we have created together over the past 20 years: jobs, innovation, inspiration and inward investment,” says Sir Martin Donnelly, president of Boeing Europe and managing director of Boeing in the UK and Ireland. “At its core, the agreement looks to the future and what more we can achieve through world-class researchers and industry working together.”

EOS extends 3DP training offer

EOS, a technology supplier in the field of industrial 3D printing for metals and polymers, is further expanding its offer in the areas of training and knowledge transfer. Back in 2016, EOS founded the consulting unit Additive Minds, which supports companies in tapping the vast potential of industrial 3D printing. The digital training of the Additive Minds Academy now complements this provision, bundling together many years of experience from consulting and
technical training.

Through blended learning formats and online/remote training, the Additive Minds Academy is taking a step towards conserving resources and thus reducing not only travel times but also training costs. The Additive Minds Academy offer includes individual learning modules and comprehensive learning paths (in English) that prepare for various roles in additive manufacturing – from machine operator and application specialist, to production manager. Customers receive support for on-boarding new employees, as well as further training for existing staff members.

Parting geometry for high feeds

For parting-off at high feed rates, Horn has introduced EH geometry, a development based on the manufacturer’s S100 grooving system. The single-edge insert is available in widths of 3 and 4 mm. Notably, the stable cutting edge enables feed rates in the range of 0.25 to 0.4 mm/rev during grooving and parting, leading to fast cycle times.

High infeed requires a stable machine, as well as secure clamping of the workpiece. From a feed rate of 0.3 mm/rev, Horn recommends reducing the infeed for the first 3 to 4 mm during grooving and parting-off.

Due to their stability, S100 holders and cassettes for grooving along the Y axis are first choice when machining at these elevated feed rates. The process enables high-performance, vibration-free parting with high cutting values, leading to short machining times, reports Horn.

Especially when parting-off workpieces of larger diameter, high moments of force begin to manifest. The space available in a machine often does not allow the use of tools featuring larger cross-sections. With the new insert arrangement in the tool holder, the cutting forces are absorbed by the main cross-section of the parting tool holder, resulting in greater overall rigidity for a given tool width and, subsequently, higher feed rates. Alternatively, it is possible to deploy a narrower holder to achieve the same system rigidity.
