摘要： An apparatus capable of automatically determining grinding wheel dressing timing for dressing a grinding wheel. The apparatus estimates the abrasion of the grinding wheel in a grinding cycle on the basis of machining data and grinding conditions, and divides the grinding cycle into a plurality of stages according to the estimated abrasion to carry out grinding wheel dressing after the completion of every stage of the grinding cycle. In grinding a workpiece having a plurality of ground sections, the abrasion of the grinding wheel in grinding each ground section is estimated, and the abrasion is accumulated in accordance with grinding sequence. A ground section after grinding which grinding wheel dressing is to be carried out is determined on the basis of the cumulative abrasion. Similarly, the abrasions are accumulated for each of workpieces. A grinding wheel dressing is carried out after the completion of grinding a workpiece so that the cumulative abrasion may not exceed a predetermined value.

摘要： An intelligent machining system employs a neural network for calculating machining conditions on the basis of attribute data or a workpiece and a grinding machine. The system comprises a reference machining condition calculating unit, a neural network which receives the attribute data and provides corrections, and a correcting unit for correcting the reference machining conditions by using the corrections. Corrections which cannot be determined by means of empirical expressions or theoretical expressions are determined appropriately by the neural network previously learned. The system determines corrections for the machining conditions on the basis of machining errors decided by a neural network. The system also detects time-series machining phenomena by sensors, processes the output detection signals of the sensors by a neural network to obtain machining circumstance data. The feed rate of the tool is controlled by a fuzzy inference on the basis of the machining circumstance data.

摘要： A numerically controlled machine tool for machining a non-circular workpiece according to profile data. The numerical controller of the machine tool memorizes the ideal profile data calculated from the ideal final shape of the workpiece, and the execution profile data calculated from the ideal profile data and compensated for position error due to the follow delay of the machine tool. The machine tool is controlled according to the execution profile data during grinding the workpiece with cut-in feed and spark-out grinding. The numerical controller has the capability of measuring position change of the main spindle and the tool slide during spark-out grinding. Then, the numerical controller ascertains whether or not the follow delays of the main spindle and the tool slide are within a prescribed tolerance depending on the measured position change and the ideal profile data.

摘要： A numerical controlled grinding machine for grinding a workpiece, in which a thermal displacement taking place between a wheel head and the workpiece, is detected with the workpiece not being subjected to the bending due to a grinding resistance. The thermal displacement is calculated from the difference between the present position of the wheel head detected by a position detector and the theoretical position thereof converted from the diameter of the workpiece measured by an in-process measuring device. The position data for the wheel head stored in a numerical controller is compensated for the calculated thermal displacement for use in the subsequent control of feed movement between the workpiece and the wheel head.

摘要： In a grinding method wherein a rotating workpiece and a rotating grinding wheel are relatively moved toward and away from each other and wherein at least three of rough, fine and finish grinding step are performed successively at high, medium and low infeed rates respectively for grinding the workpiece, the grinding wheel is retracted to a back-off position at the end of the rough grinding step. To calculate the back-off position, a first residual grinding amount which is left unground due to the bending of the workpiece is calculated based upon the diameter of the workpiece and the position of the grinding wheel which are detected respectively by an in-process measuring device and an absolute encoder at the end of the rough grinding step, and a second residual grinding amount of the workpiece at the end of the fine grinding step is estimated based upon the first residual grinding amount and a third residual grinding amount which has been calculated at the end of the finish grinding step for a preceding workpiece portion. The back-off position is calculated from the difference between the first and second residual grinding amounts.

摘要： A numerically controlled machine tool for machining a non-circular workpiece according to profile data. The servomotor drive unit of the machine tool includes a frequency voltage converter which outputs a velocity compensation signal proportional to the frequency of position command pulses in the servomotor drive units. A position error signal is modulated by the velocity compensation signal. The numerical controller of the machine tool can measure the position error and phase error, and can compensate for these errors. The numerical controller operates according to ideal profile data and measures the actual position change of a tool slide corresponding to the angle position change of a main spindle. Then, the numerical controller calculates the position error and phase error depending on the actual position change and ideal profile data, and produces execution profile data which are compensated for position error. During machining operation, the numerical controller offsets the rear out position of the execution profile data by the calculated phase error so as to eliminate the phase error.

摘要： A numerical controller is provided wherein each time one data block of a numerical control program is transferred from a second buffer register to an active register, another data block successive thereto is transferred from a data storage device to a first buffer register and wherein a plunge infeed between a cylindrical workpiece and a grinding wheel of a grinding machine is effected in accordance with data block being stored in the active register. The numerical controller halts an automatic machining operation in response to a halt command of a data block in the active register. Compensation data is input during the halt of the automatic machining operation whereafter a restart command is input. The numerical controller modified feed command data of the numerical control program stored in the data storage device, based upon the compensation data. In response to the restart command, the numerical controller transfers to the first buffer register a modified data block successive to that including the halt command, whereby the grinding wheel is moved in accordance with the modified data block transferred then to the active register.
