I was trying to imagine what kind of cuts and figured they'd be grooves of a particular depth that followed the contours of the surface. If so; Change the Z axis control into a spring loaded linear sensor that is mounted on a collar around the spindle that places the sensor in the direction of the cut? You'd need another axis to control the collar and would have to manually start the cut to get it to the proper depth. But then it would follow the varying Z of the surface as long as the sensor didn't get hung up. Okay - not easy but the "in the box" ideas were all ready posted.
