Due to different thermophysical properties of tungsten carbide (WC) and cobalt (Co), additive manufacturing of WC-Co by laser powder bed fusion (PBF-LB/M) is particularly challenging. Multi-laser exposure strategies extend the process by adding...

Additive manufacturing of continuous fibre-reinforced plastic components (CFRP) enables the cost-effective production of complex components for various industries. Laser sintering as a process has only recently been enabled for the production of...

In this work, a model was developed to produce thin-walled unalloyed steel structures with overhangs via wire arc additive manufacturing. The aim was to enable more complex geometries for non-planar printing. Preliminary tests and a full-factorial...

The classic process chain for producing hairpin stators for electric traction motors is heavily tool-based, especially the process step of twisting the hairpin winding. This article presents a simple machine module that enables a flexible,...

This study investigates whether defined influencing factors in laser welding of hairpins can be represented in multispectral process emission signals. Based on a structured experimental series, end-face geometry, focal position and material were...

The increasing demand for customized products requires flexible production systems. The focus here is on robot-assisted systems, but these often lack the necessary rigidity for high-precision machining processes. Wire EDM with two robots is...

High-pressure jetting with liquid CO2 (HPCO2 jetting) is a dry, residue-free and environmentally friendly manufacturing process with significant potential for material removal and surface processing. To generate a stable liquid CO2 jet with...

Efficient cutting fluid supply is crucial for process stability and tool life in deep hole drilling. This study focuses on the experimental validation of numerical flow simulations in single-lip deep hole drilling. CFD simulations are combined with...

This paper investigates the deformation behavior of elastic tool systems in belt grinding. Quasi-static compression tests, centrifugal force measurements, and contact-mechanical analyses are used to study the influence of contact wheel hardness hk...

This study investigates the influence of diameter variations Δd in the initial geometry as well as the flow direction and volumetric flow rate of the abrasive medium on the geometric properties of abrasive flow machined workpieces. The results show...

Electroplated nickel-bonded dental grinding tools are associated with environmental and health concerns. Within the “GreenDentalGrind” project, a sustainable copper bond is being developed as an alternative. By using titanium-coated diamond...

This article examines the influence of key process parameters on surface finishing during diamond slide burnishing of the aluminum alloy EN AW-5083. The engagement width ae proved to be the dominant influencing factor, while feed velocity vf and...

Combined vacuum brazing and hardening enables the economical production of woodworking tools with steel bodies. This paper presents a validated transient FE model that maps the temperature distribution during the holding and cooling phases. Various...

The operational precision of machine tools is constrained by the process force-induced displacements of the tool center point. Active compensation is capable of reducing the resulting geometric deviations on the workpiece. In this article, the creep...
