Superficial Tool Positioning System

      Disclosed is a method of precisely locating a tool bit relative
to a workpiece in a cutting or grinding operation.

      This method relies on the use of an acoustic or other force
transducer which detects the contact between a tool and a workpiece.
The tool is advanced to the workpiece while monitoring the output of
the transducer.  The transducer is highly sensitive to mechanical
vibrations, such as would be produced when a cutting tool engages a
workpiece.  The approach of the tool towards the workpiece is
arrested upon sensing the contact of the two elements. Using this
technique it is possible with appropriate choice of the sensor and
associated electronic signal processing system, to detect differences
in separation of tool and workpiece of better than 1000 Angstroms.

      This operation can be done when the tool is moving at maximum
speed relative to the workpiece or vice versa which is impossible to
achieve with other systems capable of operating at this accuracy.
