    摘要: A thermal displacement state (target thermal displacement state) in which thermal displacement of a machine tool is saturated when the machine tool is operated based on a machining program is previously stored, and a warm-up operation pattern of a motor is determined so as to approach the target thermal displacement state. The motor is driven based on the warm-up operation pattern and the warm-up operation of the motor is stopped if the thermal displacement state of the machine tool is within a predetermined range.

    摘要: A method and an apparatus for controlling a numerically controlled machine tool, wherein the heat generation amount and the temperature of a drive unit including a servo amplifier 15b and a feed shaft motor 3 are computed by a drive unit heat generation amount computing unit 31 by simulation, and from the computed heat generation amount and the computed temperature, the total heat generation amount of the drive unit, the cutting feed heat generation amount, the cutting load heat generation amount, etc. are computed by a feed heat generation amount computing unit 39, so that the cutting feed rate override value of the numerically controlled machine tool 1 is computed by a cutting feed rate override computing unit 27 and effectuated by being output to a NC unit. Further, based on the temperature of the drive unit computed by a computing unit 31 or the temperature computed by a temperature data computing unit 47 or the temperature detected by a temperature detection sensor 49, etc., the proper values of the feed acceleration/deceleration time constants &tgr;r and &tgr;c are computed and output as a ratio with respect to the set and stored initial values &tgr;r0 and &tgr;C0 thereby to control the NC commanded rate. The overheating of the feed axis drive unit is prevented while at the same time improving the machining efficiency.

    摘要: A method corrects thermal displacement of a machine tool having a rotational spindle. The method includes detecting a rotation speed of the spindle. A thermal displacement amount of the spindle in the current cycle of execution of a program is estimated by using an arithmetic expression that is based at least on the spindle rotation speed and a thermal displacement amount that has been estimated in the preceding cycle of execution of the program. The estimated thermal displacement amount in the current cycle is used as a correction amount for canceling the thermal displacement of the spindle. Therefore, thermal displacement of a machine tool is corrected with no complicated processes when a spindle rotation speed changes.

    摘要: A compensation system for a computer-controlled machining apparatus having a controller and including a cutting tool and a workpiece holder which are movable relative to one another along a preprogrammed path during a machining operation utilizes a camera and a vision computer for gathering information at a preselected stage of a machining operation relating to the actual shape and size of the cutting edge of the cutting tool and for altering the preprogrammed path in accordance with detected variations between the actual size and shape of the cutting edge and an assumed size and shape of the cutting edge. The camera obtains an image of the cutting tool against a background so that the cutting tool and background possess contrasting light intensities, and the vision computer utilizes the contrasting light intensities of the image to locate points therein which correspond to points along the actual cutting edge. Following a series of computations involving the determining of a tool center from the points identified along the tool edge, the results of the computations are fed to the controller where the preprogrammed path is altered as aforedescribed.
