Particularly important targets in the pad dressing are to increase the material removal rate (MRR) and a low non-uniformity (N.u.).
A higher material removal rate (MRR) is achieved by higher stresses acted on to the pad.

When machining aerospace monolithic components, most of materials could be removed, resulting in severe deformation of the parts due to the release and redistribution of the blank's original residual stress, together with the action of cutting loads and clamping force.
In the milling process, more than 90% of the materials would be removed which results in its low rigidity.
Computer Simulation The Physical Dimension and Material Properties of the Part.
The removal of the materials is realized by element birth and death technology.

Interpenetrating Phase Composites (IPC) belong to a special category of composite materials, offering great potential in terms of material properties due to the continuous volume structure of both composite components.
Composite materials are categorized according to the type of their reinforcement, being particle, fibre or interpenetrating reinforcements.
Resonant frequency damping analysis are carried out in cooperation with RWTH Aachen University, Division of Materials Science and Engineering.
