A method for repairing a bone of a patient may include superimposing a first virtual boundary on a virtual bone and superimposing a second virtual boundary on the virtual bone. The method may further include robotically modifying the bone of the patient with a planar tool along a first working boundary to create a first surface. The first working boundary may correspond to the first virtual boundary. The method may further include robotically modifying the bone of the patient with a rotary tool along a second working boundary to create a second surface. The second working boundary may correspond to the second virtual boundary.
