  • Patent number: 9687991
    Abstract: 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.

  • Patent number: 8424427
    Abstract: There is provided a roll surface machining method and apparatus for using a cutting tool to carry out ultra-precision machining in the surface of a roll with a reduced amount of data. The apparatus and method for roll surface machining includes setting a machining start position of a cutting tool with respect to the surface of the roll by C-axis indexing of the roll and positioning of the roll in the axial direction (Z-axis direction) both with respect to the cutting tool. Also the cutting tool and the roll are moved relative to each other in the axial direction of the roll by position control using C-Z axis interpolation, thereby forming a three-dimensional pattern in the surface of the roll.
