Learning Factories towards Industry 5.0: Evolutionary or Revolutionary?

Péter Wolf Ferenc Kása Tamás Gyulai Zsolt János Viharos

Publication Name: 19th Imeko Tc10 Conference Macro Meets Nano in Measurement for Diagnostics Optimization and Control

Description:

Rather than representing a technological leap forward, Industry 5.0 actually nests the Industry 4.0 approach in a broader context, providing regenerative purpose and directionality to the technological transformation of industrial production for people-planet-prosperity [1]. Consequently, Industry 5.0 can be considered as the new engine of the economic and societal transition with a societal concept which can mean more distributed well-being with human-centric and sustainable, resilient industry. The advantage of the learning factory concept therefore lies in the combination of the realistic factory environment, processes and transparency of the structured activities which can provide testing of new features, modules, functionalities, tools, and technologies based on the existing Industry 4.0 framework. Especially, the concepts of implementing new business models with benchmarking emphasise the major difference in achievable results. Transition to a circular economy can only be achieved if up-skilling and re-skilling of workers can also be done which is the core function of the learning factory.

Experimental and numerical investigation of the single-point incremental forming of aluminium alloy foils

Imre Paniti Sherwan Mohammed Najm Dóra Harangozó Zsolt János Viharos

Publication Name: Acta Imeko

Volume: 9

Issue: 1

Page Range: 25-31

Description:

Single-Point Incremental Forming (SPIF) is a flexible process for manufacturing sheet metal parts that is well adapted and profitable for prototypes or small batch production. Compared to traditional sheet forming technologies, this relatively slow process can be used in different applications in the automotive and aircraft industries; architecture engineering; and medical aid manufacture. In this article, the indirectly obtained axial forming force on the SPIF of variable wall angle geometry is studied using different process parameters. The estimation of the forces on AlMn1Mg1 sheets with an initial thickness of 0.22 mm is performed by continuous monitoring of servomotor currents. The deformation states of the formed parts were analysed using the ARGUS optical strain measurement system of GOM, while the roughness measurements were carried out by a Mitutoyo system. Some initial finite element analysis simulations and a crack monitoring method together with an interaction plot of forming speed, incremental depth, tool diameter, and lubrication were also reported.

Description:

Incremental Sheet Forming is a prosperous process to manufacture sheet metal parts that is well adapted for prototypes or small batch production. Compared to traditional sheet forming technologies this relatively slow process is only profitable for the above mentioned production types but it can be used in different applications in automotive and aircraft industries, in architecture engineering and in medical aids manufacturing. In this paper indirectly obtained axial forming force on Single Point Incremental Forming (SPIF) of variable wall angle geometry were studied under different process parameters. The estimation of the forces on AlMn1Mg1 sheets with 0.22 mm initial thickness is performed by continuous monitoring of servo motor currents. The deformation states of the formed parts were analysed using the ARGUS optical strain measurement system of GOM. Interaction plot of forming speed, incremental depth, tool diameter and lubrication were also reported.
