Abstract
A cold-gas-blow-cooling type machining apparatus including a relative movement device which moves a workpiece and a machining tool relative to each other, and a cold-gas-blow supply device which supplies a cold gas blow to a machining point at which the workpiece is machined by the machining tool. The machining apparatus includes: a workpiece-temperature detecting device which detects a temperature of the workpiece; and a machining-condition control device which controls at least one of the relative movement device and the cold-gas-blow supply device, on the basis of the detected temperature of the workpiece. The machining-condition control device includes a cooling-condition control device which controls the cold-gas-blow supply device so as to control at least one of a temperature and a flow rate of the cold gas blow.
