  AfM Technology GmbH is an international solution provider in the field of mobile measurement technology based in Germany. The focus of the company lies in the metrological detection and correction of geometric guide deviations within machine tools, coordinate measuring machines, robot systems and other multi-axis machine systems.

  Volumetric Compensation of geometrical deviations

  Determination of geometrically reproducible translational and rotational deviations of machine axes. Based on the determined deviations a correction field is created for SINUMERIK CNCs. Depending of the machine position ensue the correction of all single deviations at the tool center point (TCP) to the running time of the machine.

  Функции

  Due to the manufacturing process, machine axes deviate from their ideal geometrical shape and are never exactly perpendicular to each other. The existing geometrical deviations lead to translational and rotational deviations which have the effect that the actual position deviates from the target position.

  • AfM Technology GmbH acquires the existing, individual geometry deviations of all axes with special measuring methods.
  • From the individual errors, AfM Technology GmbH can generate a machine-specific error map for the CNC and deposit it in the control.

  By knowing the single deviations from the error map, the SINUMERIK VCS option is able to calculate the deviation at the tool center point (TCP) to the running time at every position in the volume. Based on the calculated value, the control changes its actual position in direction to the target position at the tool center point. Significant increases in machine accuracy and machined products are the result.
