High-Performance Cutting of Micro Patterns

High performance cutting of advanced aerospace alloys and composite materials

“…A higher surface quality when vibration assisted milling titanium alloys was determined by Ostasevicius et al [165]. Denkena et al [55] used the technology of VAM in milling in order to create micro patterns on the surface of Ti6Al4V.…”

Simplification of the Model of Piezoelectric Actuator Control Based on Preliminary Measurements

“…The advantage of ultrasonic vibration systems is that they operate in their design-based resonance and that exact and controlled positioning is not necessary. Due to the design, a very high mechanical natural frequency can be achieved with the FTS systems (1 kHz to 5 kHz) [3][4][5]. The systems are uniaxial, simple and only a very small part, usually the tool with cutting edge, is moved.…”

FTS-based Face Milling of Micro Structures

“…Due to the fact that highly dynamic operations cause a significant heat development, a ring-actuator is used for a better heat dissipation. At the maximal used voltage of Umax = 500 V, the actuator has a force of 10 kN and a travel range of Δlmax= 30 μm [2]. The controlled cutting of micro structures requires oscillation frequencies below the eigenfrequency due to occurring phase shifts above this frequency range.…”

“…1). This approach was successfully performed in [2] with a specially designed piezoelectric face milling tool. In addition to that, the tool concept opens up new possibilities in the area of machining micro structures on work pieces of various size and shape.…”

“…1. Machined binary patterns for information storage on a component's surface [2] The tool is capable of deflections up to 4 kHz with an amplitude up to 30 μm. In terms of plagiarism protection, the capabilities can be extended in machining of individual structures or patterns.…”
