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
