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.

摘要： A numerical controller for a grinding machine is provided with a memory device, a data processor, a data input device, a display device and a manual pulse generator. After the setting positions of a grinding wheel carrier, a tail stock and the like of the grinding machine are changed in connection with the replacement of a grinding wheel with new one and the change in kind of workpieces, the input device is manipulated to display a desired one of images on the display device. The manual pulse generator is then operated to move components such as the grinding wheel carrier and a work table to a state indicated by the displayed image, and a storage command switch of the input device is depressed. In response to this depression, the data processor reads the present positions of the components in the state displayed on the display device and calculates based upon the read present positions data which is used in numerically controlling a machining operation of the grinding machine. The data processor carries out such calculation using one of equations determined depending upon the state being displayed on the display device and then, stores the calculated data in a storage area of the memory device determined by the state being displayed on the display device.

摘要： A method of grinding a curved corner portion of a workpiece by a grinding wheel having a curved edge surface whose radius is smaller than that of said curved corner portion. The grinding wheel is movable along a path extending at an acute angle to the axis of rotation of the workpiece. First, the grinding wheel is relatively moved to a first grinding start position. Then, the grinding wheel is moved inwardly to an advanced position along the path so as to perform a plunge grinding operation, and is subsequently retracted to the grinding start position. After that, the grinding wheel and the workpiece are relatively moved so as to move the grinding start position to the next grinding start position along a curved arc which is in parallel with the curved corner portion of the workpiece. The above plunge grinding operation is repeatedly performed from each grinding start position thereby grinding the curved corner position.

摘要： A numerical controller for a grinding machine, wherein one of plural reference sizing points is selected according to the contents of a numerical control program. Measured analog data indicating the diameter of a workpiece is received continuously to determine if the size of the machined workpiece coincides with the selected reference sizing point. Upon the coincidence of the size of the machined workpiece with the reference sizing point, a sizing signal is provided, and then machining control is changed in response to the sizing signal. An analog signal provided by a measuring device is sampled at a predetermined interval in a predetermined time. The analog signal is tested to see if the analog signal is in a predetermined range, which is decided based upon the temperature variation or vibrations of the grinding machine. And the result of the test is displayed to facilitate checking the output characteristics of the measuring device. The analog signal is compared with a predetermined reference value, and then the result of the comparison is displayed together with a predetermined reference value.

摘要： A numerical controller for an angular slide grinding machine capable of controlling movement of a work table with a dressing tool in a machine coordinate system in a dressing operation and a workpiece coordinate system in a grinding operation. When the work table is initially moved to such a position as to bring the dressing tool into slight contact with an end surface of a grinding wheel carried by a wheel head, the numerical controller calculates and stores a dressing reference value indicating a positional relation between a fixed machine origination position and the dressing tool in the machine coordinate system. Prior to grinding operations for each workpiece, the work table is moved under the control of a sizing device to such a position as to present a reference surface of the workpiece to a predetermined positional relation with the original machine position. The numerical controller at this time calculates and stores a coordinate difference between the machine coordinate system and the workpiece coordinate system. When a dressing operation is needed following a grinding operation, the numerical controller calculates a dressing start position or coordinate value of the work table in the machine coordinate system based upon the dressing reference value previously calculated and stored and a dressing start coordinate value of the wheel head indicated by a present position counter for the wheel head and then, converts the calculated dressing start coordinate value into a corresponding coordinate value in the workpiece coordinate system based upon the coordinate difference previously calculated and stored.

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.
