摘要： The position of a feed shaft is monitored, the mean moving speed and moving frequency of the feed shaft are measured with every unit time for position correction, and a correction amount &dgr;n is determined from the speed and frequency according to an approximation formula and updated (c7 and c8). A position correction amount for a commanded position is determined from this correction amount, and the commanded position is corrected by the position correction amount (c1 to c6). The position correction amount for the commanded position is determined from this correction amount, and the commanded position is corrected by this position correction amount. Since the correction amount is determined according to the approximation formula, thermal displacement correction can be effected at all times without requiring any sensor. When the correction amount changes substantially (c10), the thermal displacement is measured by means of a sensor and used as the correction amount (c11 and c12), whereby accuracy is improved. The frequency of measurement by means of sensors is reduced, so that the machining time can be reduced.

摘要： Actual machining positions P1, P2, . . . corresponding to command positions S1, S2, S3 . . . of each block of NC data are obtained by trial machining. Positions that correspond symmetrically to the actual machining positions P1, P2, . . . with respect to the command positions S1, S2, S3 . . . of each block are obtained. Modified NC data are created with use of the symmetrical positions as modified command positions for each block. The modified NC data include correction values for modifying positional differences attributable to a delay in a servo system. Therefore, if machining is carried out in accordance with the modified NC data, the correction values and a follow-up delay attributable to the actual delay in the servo system cancel one another, so that a high-accuracy work shape can be obtained.

摘要： In a thermal displacement compensation method for a machine tool, in which a feed shaft thermal displacement amount is obtained and an amount which cancels the obtained feed shaft thermal displacement amount is added as a thermal displacement compensation amount to a position command for a feed axis, a position where a signal is first output by a position sensor for detecting the position of a movable part of the machine tool is first stored as an initial position. Then, the position where the signal is output by the position sensor is detected, and the thermal displacement compensation amount is modified according to a compensation error, which is the difference between the detected position (actual position) and the initial position.

摘要： A machine tool capable of detecting an ambient temperature change without a detector for detecting the ambient temperature and capable of detecting an abnormality of a temperature detector for detecting the motor temperature. Motor temperature Ti (i=1, 2 . . . n) and the current feedback Ifi of each motor are read out from the temperature detector for detecting the temperature of each motor of the machine tool. The heating value Qi of each motor is obtained from current feedback Ifi. Motor temperature Ti is calculated and estimated from the heating value Q. Difference ΔTi between the estimated motor temperature Tmi and the detected temperature Tsi is obtained. When difference between maximum and minimum values of difference ΔTi exceeds the first threshold value β, a temperature detector abnormality is outputted. When it is equal to or less than the first threshold value β, the mean value ΔT′ of differences is obtained. If the mean value ΔT′ is equal to or less than the second threshold value γ, it is determined that there is no abnormality. If it is equal to or more than the second threshold value γ, the indication that the ambient temperature has been changed is outputted.

摘要： A tool damage/abnormality detecting device capable of easily appropriately setting an allowable range for a value of comparison between a present value and a near past average for indexes indicative of loads on a tool. A machining cycle counter index i is adjusted to i=0, machining is performed as the loads are detected in a given period, and indexes H(i) (area S of load values, absolute value (G−) of a maximum inclination between two points obtained during a decrease of loads, etc.) are acquired for n number of cycles. Thereafter, the indexes and values of comparison between the index value for a present cycle and the indexes for the n number of cycles are acquired. A first comparison value can be used for initial value setting for threshold values. If any of the comparison values is deviated from the allowable range, the threshold values are updated so that the allowable range extends, and an update history is saved. If damage/abnormality is observed visually or in any other manner, a threshold value update discontinue command is inputted, machining is stopped after completion of the cycle concerned, and update values for the latest threshold value are collected to be used as set threshold values.
