Continuous generating gear grinding is characterized by the strict coupling of certain axis movements of the machine. The rotational velocities of workpiece ω 1 (C-axis) and tool ω 0 (B-axis) are synchronized in accordance to their teeth ratio so that the teeth of the workpiece (z 1) are immersed in a gear of the grinding worm (z 0), see Figure 1(A).In order to maintain a …

More specifically, the acoustic sensor can be coupled to one of the two centers, or to a grinding wheel balancing device, if applied to the grinding machine. Instead, the force-detecting sensor can be arranged between an intermediate support of the piece, or a steady rest, if included, and the base of the machine.

By contrast, synchronizing the workpiece and grinding wheel provides better pitch accuracy for gear grinding machines that use a higher grinding force. A synchronized honing machine works by synchronized driving for both the gear honing wheel and workpiece like a grinding machine. A synchronized horning machine is provided only by Kanzaki in Japan.

Uneven acoustic signatures or peaks and troughs can indicate a poor dress pass, leading to component quality issues. The AEMS product can tell the grinding machine CNC that the acoustic signal has dropped below, or risen above an acceptable level during a dress cycle. The CNC can then repeat dressing until a good wheel profile is reached.
