1. A system comprising:
a processing device; and
a memory device that includes instructions executable by the processing device for causing the processing device to:
receive real-time data for a drilling operation that is concurrently occurring with receiving the real-time data;
determine, for a drilling depth, a rotations-per-minute (RPM) value corresponding to a resonance speed based on a weight-on-bit (WOB) value and the real-time data;
determine, for the drilling depth, a second RPM value corresponding to the resonance speed based on the WOB value and the real-time data;
generate a plot of the WOB value, the RPM value, and the second RPM value corresponding to the resonance speed;
remove a coordinate corresponding to the second RPM value from the plot based on the second RPM value being associated with a lower stress and a lower displacement than the RPM value;
determine drilling parameters for the drilling operation based on the plot, the drilling parameters excluding, for the WOB value, the RPM value corresponding to the resonance speed; and
cause drilling equipment to implement the drilling parameters in the drilling operation by sending the drilling parameters to the drilling equipment as control setpoints.
