Teaching and research group – Ablating Technologies and Manufacturing Equipment

Research Interests

Microstructuring of metal components with closed electrolyte jet (Jet-ECM) or pulsed ECM (PECM)
Enables machining via turning, drilling, grinding, and cutting
Generation of functional surfaces to optimize the properties for friction and heat transfer as well as for the application of microfluids
Application of the CAD-CAM software, developed at TU Chemnitz

Abrasion via very short electric impulses
High-precision machining, regardless of strength and toughness of the component material
Allows for the manufacturing of very deep microstructures with complex geometries, e.g. drills with undercuts, nozzle geometries, etc.
Diameter starting at about 50µm, aspect ratio 20 and more
Additional optimization of the process via superimposement of vibrations with low-frequency or ultrasound
Machining of electric nonconductive ceramics possible due to special techniques

High-precise manufacturing of surface structures via laser abrasion
Laser drilling, cutting, trimming, and surface hardening
Extended machining diversity due to the process combination of laser and chipping
Allows for the Machining of different materials at a speed of up to 2.0 m/s
