text: This paper deals with the modeling of a soft sensor for detecting α’-martensite
evolution from the micromagnetic signals that are measured during the reverse
flow forming of metastable AISI 304L austenitic steel. This model can be prospectively
used inside a closed-loop property-controlled flow forming process. To achieve
this, optimization by means of a non-linear regression of experimental data was
carried out. To collect the experimental data, specimens were produced by flow
forming seamless tubes at room temperature. Using a combination of production
parameters (like the infeed depth and feed rate), specimens with different α’-martensite
contents and wall-thickness reductions were produced. An equation to compute α’-martensite
from both specific production-process parameters and micromagnetic Barkhausen
noise (MBN) measurements was obtained using numerical methods. In this process,
the behavior of the quantity of interest (namely, the α’-martensite content) was
mathematically evaluated with respect to non-destructive MBN data and the feed
rate that was used to produce the components. A combination of exponential and
potential functions was defined as the ansatz functions of the model. The obtained
model was validated online and offline during the real flow forming of workpieces,
obtaining average deviations of up to 7% α’-martensite with respect to the model.
The implementation of the soft sensor model for property-controlled production
represents an important milestone for producing high-added-value components on
the basis of a well-understood process-microstructure-property relationship.

text: "This paper deals with micromagnetic measurements for online detection of\r\nstrain-induced
α’-martensite during plastic deformation of metastable\r\naustenitic steel AISI
304L. The operating principles of the sensors are\r\nBarkhausen noise (MBN) and
eddy currents (EC), which are suitable for\r\ndetection of microstructure evolution
due to formation of ferromagnetic\r\nphases. Nevertheless, the description of
the calibration and\r\ntransformation models of the micromagnetic measurements
into\r\nquantitative α’-martensite fractions is beyond the scope of this paper.\r\nThe
focus will be put on the qualification of different micromagnetic\r\nmethods as
well as of different measurement systems under conditions\r\nsimilar to the real
ones during production, which is crucial for\r\nimplementation of a property-controlled
flow forming process. The\r\ninvestigation was carried out on tubular specimens
produced by flow\r\nforming, which have different content of α’-martensite. To
characterize\r\nthe sensitivity of the sensors, different contact conditions between\r\nsensors
and workpieces were reproduced. MBN sensors are suitable for\r\ndetecting amount
of α’-martensite, but the measurements are affected by\r\nthe surface roughness.
This entails that the calibration models for MBN\r\nsensors must take account
of these effects. EC sensors show a closer\r\nmatch with the amount of α’-martensite
without having major affectation\r\nby other effects."

text: Incremental nonlinear dynamic inversion (INDI) is a widely used approach to
controlling UAVs with highly nonlinear dynamics. One key element of INDI-based
controllers is the control allocation realizing pseudo controls using available
actuators. However, the tracking of commanded pseudo controls is not the only
objective considered during control allocation. Since the approach only works
locally due to linearization and the solution is often ambiguous, additional aspects
like control efforts or penalizing the deviation of certain states must be considered.
Conducting the control allocation by solving a quadratic program this results
in a considerable number of weighting parameters, which must be tuned during control
design. Currently, this is conducted manually and is therefore time consuming.
An automated approach for tuning these parameters is therefore highly beneficial.
Thus, this paper presents and evaluates a model-based approach automatically tuning
the control allocation parameters of a tiltrotor VTOL using an optimization algorithm.
This optimization algorithm searches for optimal parameters minimizing a cost
functional that reflects the design target. This cost functional is calculated
based on a test mission for the VTOL which is conducted within a simulation environment.
The test mission represents the common operating range of the VTOL. The simulation
environment consists of an aircraft model as well as a model of the INDI-based
controller which is dependent on the control allocation parameters. On this basis,
model-based optimization is conducted and the optimal parameters are identified.
Finally, successful real-world tests on a 4-degrees-of-freedom testbench using
the identified parameters are presented. Since the control allocation parameters
can significantly influence the aircraft’s stability, the 4-DOF testbench for
the aircraft is required for rapid validation of the parameters at a minimum amount
of risk.

text: Manufacturing processes benefit from property control enabling reproducibility,
application oriented outcomes, and efficient part production. In reverse flow
forming, state of the art practices focus primarily on geometry control, neglecting
property control. Given the intricacies of the process involving the interaction
of tool and machine behavior, process parameters, properties of semi finished
products and temperatures, incorporating process control becomes an imperative
for producing components with predefined properties. The property controlled within
this reverse flow forming process is the local α’ martensite content. Therefore,
process strategies to actively influence the α’ martensite content must be implemented.
In this study seamless AISI 304L steel tubes are used, where α’ martensite formation
is strain and/or temperature induced through phase transformation within the
process. This paper presents innovative process strategies, methods, and specially
developed mechanical and thermal actuator systems to locally increase or suppress
the α’ martensite content. The use and implementation of these approaches and
tools allows the creation of unique optically invisible microstructure profiles
containing 3D gradings, implying a radial grading of α’ martensite. The locally
implemented α’ martensite, forming these 3D gradings, offers potential applications
for functional or sensory purposes. This paper extends beyond theoretical concepts,
providing tangible component outcomes.

text: Increasing the sustainability and resource efficiency of forming processes
is one of today's major goals. High-strength wire materials are usually available
as strip material and are subjected to a downstream forming process such as punch-bending
to produce parts for the electronics industry, for example. During the manufacturing
process of the semi-finished product, residual stresses and plastic deformations
are introduced into the wire by rolling and drawing processes. Straightening machines
are used in the production lines to compensate for these. To increase the sustainability
of these production lines, the straightening process is an essential step. Before
the continuous manufacturing process starts, the straightening process must be
set up and the optimal roller positions must be found. Once the process is set
up, the roller position settings are usually not changed. Due to missing measurement
systems for the straightening quality, it is not possible to dynamically adjust
the positions of the straightening rollers to variations in the material properties.
This leads to deviations in the dimensional accuracy of the components to be produced
and thus to an increase in the rejection rate in the manufacturing processes.
To reduce the rejection rate, a novel control system for a continuous feedback
control of a straightening process is presented in this paper. This leads to a
reduction of the rejection rate and unnecessary preforming operations in wire
straightening process. The result is an increasing sustainability and efficiency
of these production process.

text: The incremental flow forming process is currently enhanced in research context
by special closed-loop property control concepts to increase the productivity
and to control the product properties making invisible property structures like
a magnetic barcode possible. However, it is preferred to establish property control
concepts on single roller machines instead of conventional machines with three
roller actuation due to the better machine accessibility. For those single roller
machines, rather poor surface qualities of flow formed workpieces were observed
in the past especially for hydraulic actuators. Thus, a new actuator closed-loop
position control concept is developed in this paper using model-based control
design methods and taking the flow forming forces as a load into account. The
novel closed-loop control is validated during workpiece production at the actual
single roller flow forming machine. An analysis of the manufactured workpieces
show that the surface quality is significantly enhanced by the new control to
a roughness level almost similar to conventional three roller flow forming. Thus,
a sincere added value to the flow forming process is offered by the novel actuator
closed-loop position control.

text: In multi-stage bending and straightening operations cross-stage and quantity-dependent
effects crucially affect the quality of the end product. Using punch-bending units
in combination with a mechatronic straightening device can improve the accuracy
and repeatability of product features remarkably well. In this work a concept
for an innovative hybrid model of a roll straightener in a multi-stage straightening
and multi-stage bending process is proposed. This model combines data-driven elements
with expert knowledge and aims to minimise residual errors of the roll straightener
to reliably decrease the risk of disadvantageous cross-stage and quantity-dependent
effects on a subsequent punch-bending process.

text: In manufacturing, property control ensures efficient part production. However,
in reverse flow forming, current practices focus on geometry control rather than
property control. To address the complexity of the process and tool machine interaction,
process control is crucial for defined component properties. This study focuses
on controlling local α’ martensite content in reverse flow forming of seamless
AISI 304L steel tubes. Strategies and systems are presented to influence α’ martensite
content, creating unique microstructure profiles for 1D and 2D Gradings, with
tangible component outcomes.
