TESTE DEIN WISSEN

Abrasion

Adhesion

Surface fatigue

Tribochemical wear

TESTE DEIN WISSEN

Define vertical process chain and horizontal process chain

Lösung anzeigen
TESTE DEIN WISSEN

Vertical process chain describes single process steps (efficiency)


Horizontal process chain describes the process sequence (effectiveness)

TESTE DEIN WISSEN

Explain the general machining process with ECM.

Lösung anzeigen
TESTE DEIN WISSEN

A external voltage is applied to two electrodes. Between the electrodes there is an electrical conductive fluid. Due to the electrical discharge and the movement of the the cathode (tool), particles are removed from the anode (workpiece) and the geometry of the tool is shaped into the workpiece.

TESTE DEIN WISSEN

Define cutting wedge and name three functions of it.

Lösung anzeigen
TESTE DEIN WISSEN

Cutting wegde can be found on every tool used for machining with geometrically defined cutting edges.


Its main functions are:

Chip formation

Surface formation

Separation/Cutting of material

TESTE DEIN WISSEN

When does wrinkling occur?

Lösung anzeigen
TESTE DEIN WISSEN

Wrinkling occurs if:

–Resistance against buckling is not high enough

–Process is carried out without blankholder

–Blankholder force is too low

TESTE DEIN WISSEN

Your manager comes to you and says: "We are upgrading the LPBF system tomorrow with a second laser. This will enable us to halve the total production time for two components on the LPBF system". Is this statement from your manager correct from a technological point of view? Justify your answer.

Lösung anzeigen
TESTE DEIN WISSEN

Wrong, because the total production time is influenced by the powder application time and the exposure time. The second laser will halve the exposure time but it doesn't affect the powder application time.
