    摘要： A method and device for controlling a machine tool numerically, in which a drive means generated heat calculating section (31) simulation-calculates the heat generated by drive means (3, 15b) and the temperature thereof, a by-feed-type generated heat calculating section (39) calculates the total amount of heat generated by the drive means (3, 15b), the amount of heat generated by the cutting feed, and the amount of heat generated by the cutting load, a cutting feed speed override calculating section (27) calculates a proper cutting speed, and a rapid-traverse/cutting-feed acceleration/deceleration time constant calculating section (21) calculates a proper rapid-traverse acceleration/deceleration time constant τr, and a proper cutting-feed acceleration/deceleration time constant (τc), and outputs the time constants to an NC, thereby improving the machining efficiency while preventing overheat of the drive means (3, 15b).

    摘要： A method of controlling a numerically controlled machine tool provided with a plurality of feed rods is provided to achieve high-precision machining even if moving parts of the machine are moved at high speed. This method comprises predicting suitable command values corresponding to the friction of the feed mechanism of a numerically controlled machine tool as well as the change in weight of a workpiece; and supplying the suitably predicted command values to a drive unit to drive a feed motor.
