performance on different materials, such as
steel, carbon steel, alloy steel, stainless
steel and aluminium. They deliver
continuous and reliable tapping, as well as
extend significantly the tool life, thanks to
exceptional chip evacuation. An innovative
flute design allows optimal chip control and
lower cutting forces, resulting in excellent
finish quality. The taps are made with
premium quality powder high speed steel,
based on Yamawa’s own specifications,
and feature a new special coating to
maximise wear resistance ● An advice
service for tapping-related problems and
challenges will be hosted in the company’s
‘Ask the experts’ area. ■

Adding capability through exoskeletons – Professor Jens P
Wulfsberg develops interdisciplinary technical support systems
for production at the University of the Federal Armed Forces in
Hamburg (LaFT). But the development work is not carried out for
the military, he explains. Ergonomic Smart Assist aids are being
developed at Laboratory of Production Engineering (LaFT), part
of the Faculty of Mechanical Engineering at Helmut Schmidt
University, University of the Federal Armed Forces. More than
20 different exoskeletons have already been developed – from
ankle orthoses to muscle gloves.
“The aim of our exoskeletal systems is to help reduce
workplace injuries,” explains sports scientist Andreas Argubi-
Wollesen, senior biomechanic at the LaFT-Institut für
Konstruktions- und Fertigungstechnik (LaFT Institute for
Construction and Manufacturing Engineering). “Our systems are
designed to take the muscular strain out of certain tasks and
not to cause additional problems through their own weight.”
Says Wulfsberg, looking back: “We didn’t set out to create
an exoskeleton. We were given the task of developing support
components. The first request came from the Airbus plant in
Hamburg, which wanted to relieve the strain on its workers
while carrying out overhead work.” The first functional models
were tested there back in 2016. The main focus is on
prevention – reducing the number of days lost to sickness,

The Hamburg researchers also have their sights set on
machine assembly. They have developed small machine tool
feed unit with two degrees of freedom driven by two piezo
actuators (travel range: 1.6 by 3.5 mm, accuracy: 1 micron).
The drive element is intended for use in the construction of
small machine tools required for ‘microproduction’, the
manufacture of very small components such as those used in
medical technology or the watch industry. A technician is
assisted by movable elements that provides support for arms
while they are working. These are tailor-made grip plates that
LaFT produces via 3D printing. The Hamburg-based researchers
use a robot to monitor the assembly processes. The robot’s
sensors can be used to record the paths travelled and the
forces.
Says Wulfsberg: “We can use the recorded motion
sequences to refine the assembly process.” Practical
application in the field of medical technology is already planned.
He concludes: “I am also keen to discuss the construction of
small, inexpensive machine tools for microproduction with
manufacturers in Hanover.” Chiron, Benzinger, Datron,
Fehlmann, GF Machining, Hermle, Kern, Kummer, Schaublin
Machines, Sodick, Willemin-Macodel and Yasda are some of
the suggested possible candidates at EMO.
