A press apparatus according to an embodiment includes an upper die and a lower die, and configured to manufacture a different-thickness metal plate, in which: the lower die includes: a wall surface facing a cavity; a fixing part configured to fix both ends of the metal plate, the both ends of the metal plate being placed so that its plate surface faces upward; and a rotating mechanism configured to rotate the metal plate so that the metal plate is brought into an upright position along the wall surface; and the upper die includes: a slide moving part including an opposed surface opposed to the wall surface and configured to descend in the cavity along the wall surface; and a cutting tool disposed on the opposed surface; and shaving is carried out on at least a part of the plate surface of the metal plate.

A spindle motor rotates a spindle to which a cutting tool is attached. A feed mechanism moves the cutting tool relative to a thin workpiece. A machining apparatus repeatedly performs a first process of causing the feed mechanism to feed the cutting tool relative to the thin workpiece in a height direction of a rising wall to perform a plunge process on the thin workpiece, and a second process of causing the feed mechanism to feed the cutting tool relative to the thin workpiece in a width direction or the height direction of the rising wall to perform a finishing process on the thin workpiece.

An apparatus for cutting a profile, including: a cutter configured to make cuts on the profile having a first surface and a second surface, and having at least one rib on the first surface, wherein the cuts are made on the first surface of the profile; a first drive unit to drive the cutter forward and backward to and from the first surface of the profile; and a second drive unit to drive the cutter up and down along the first surface of the profile.

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.
