An apparatus and method are provided for three dimensional planing of a workpiece. The apparatus includes a base, a displaceable machine table supported on that base, a displaceable spindle supported on the base adjacent the machine table, a cutting tool held in a chuck carried on the spindle and a control module. The control module includes a controller and a plurality of actuators to provide precise displacement of the machine table, spindle, cutting tool and the workpiece for planing surface features into the workpiece.

A microscopic geometry cutting device includes: a controller that outputs a timer count start command in starting a driving program which controls a drive of an X-axis or a Y-axis moving mechanism; an arrival time calculator that calculates an arrival time from when the timer count start command is output till when the cutter arrives at a machining start position in accordance with relative moving speed information of the moving mechanisms and machining start position information of a workpiece W; an elapsed time determiner that determines whether an elapsed time from when the timer count start command is output is coincident with the arrival time and outputs a trigger signal when the elapsed time is coincident with the arrival time; and a reciprocating stage driver that drives the reciprocating stage in a manner that the cutter advances and retracts in a predetermined cutting depth in response to the trigger signal.

The present disclosure relates to the technical field of cutting machining, and discloses a cross-scale structure feature surface machining method based on a multi-component collaborative vibration. A vibration in a z-axis direction is applied to a servo movement mechanism to realize the cutting of a micron-scale structure and the adjustment of the cutting depth; and the vibration in the z-axis direction is applied to a three-axis movement platform to realize the cutting of a millimeter-scale structure and the adjustment of the cutting depth. A required cross-scale structure feature surface can be machined and formed at one time through a collaborative vibration among a vibrating tool, a servo movement mechanism, and/or a three-axis movement platform according to the structure type contained in the required cross-scale structure, which can simplify a process flow and improve the machining efficiency, and has high economic efficiency.
