Machining for highest quality and optimization of CFRP and Inconel components
High-speed machining of Inconel 718
New machining technologies for highest quality – Advanced VAM | deterministic MHP
Advanced vibration-assisted machining – VAM
- considerable improvements of tool life and chip breaking are possible compared to conventional VAM methods
- improved chip breaking, optimized chip removal, reduced cutting forces, longer tool life
- improved quality of the finished workpiece – reduced fraying, delamination, chipping at tool exit
- particularly efficient for machining of aircraft material, like CFRP and stacks
Innovation level:
- design and operation of a vibrating spindle with a hydraulic actuator for the z-axis and piezoelectric actuators for the x- and y-axis
- allowing for highly effective low-frequency oscillations with amplitudes of about 100 to 400 μm along the z-axis
-----------------------------------------------
Surface functionalization by deterministic machine hammer peening
- specific manipulation of structure (roughness, smoothness, micro-geometry) and hardness as well as the magnetic, thermal, electrical, and chemical properties of technical surfaces
- reduction of flow resistance
- replacement of manual polishing processes and/or substitution of thermal hardening processes
- synchronous monitoring of material characterization and detection of material inhomogeneities during the process of machining
- invisible 3-dimensional coding option for components
- due to an automated machining process, integration into existing process chains – without reclamping the workpiece
Innovation level:
- unique actuator system allowing for control and monitoring of the entire mechanical surface treatment process in-lin
- due to the highly dynamic short-stroke linear reluctance motor each single movement of the hammer can be accurately set and controlled
- acceleration values of available systems are exceeded by a factor of ten and more
- offering protection against undesirable kickback forces on machine components
