    摘要: A wire electric discharge machine and a wire electric discharge machining method in which a workpiece set posture is compensated for an error. After a workpiece is set and fixed on a workpiece table, an upper guide measures three or more three-dimensional positions that are not situated on one straight line on an upper surface of the workpiece, utilizing detection of contact with the upper surface. A unit normal vector Nincl (Xn, Yn, Zn) is obtained, and a shift amount Δshif (ΔU, ΔV) for shift from an originally set vertical position (U0, V0) to a corrected position (Uc, Vc) is calculated. In machining, the shift amount Δshif (ΔU, ΔV) is added to the position (U0, V0) to compensate for an angle error of a machined surface, and a deviation of a machined point position caused by inclination of the workpiece is collaterally compensated for as required by correcting the upper and lower wire guides. Thus, the machined shape cannot be distorted, and the workpiece set posture error can be compensated for.

    摘要: A cut contour display method in a wire electric discharge machine for subjecting a workpiece to taper cutting by moving a workpiece relative to a wire electrode and moving a wire tensioning guide horizontally has a first step of entering a programmed path (WDP) lying on the lower surface of the workpiece, workpiece thickness, data including a taper angle or a vector indicating a positional offset between the upper and lower surfaces of the workpiece, and data specifying a number of cross-sectional contours. A second step includes obtaining a wire electrode path (WUP) on the upper surface of the workpiece, which is not a programmed surface, by using the programmed path (WDP), workpiece thickness, and the taper angle or vector indicative of the positional offset. A third step includes obtaining coordinate values of points on each cross-sectional contour at an end portion of each block by using data indicative of the wire electrode paths on the upper and lower surfaces of the workpiece and the number n of cross sections. A fourth step includes displaying, on a display unit, the wire electrode paths on the upper and lower surfaces of the workpiece, as well as each cross-sectional contour of the taper-cut surface, by using the data indicative of the wire electrode paths on the upper and lower surfaces of the workpiece and coordinate values of the points on each cross-sectional contour at the end portion of each block.

    摘要: A data update system in a bubble memory in which, to preserve the simultaneity of data in the event of a power failure during the updating of data in the bubble memory, initialization data is written into a specific data storage area of the bubble memory the initialization data indicates that the data in a first data storage area is invalid, and new data is subsequently written into the first data storage area from a first record to a last record successively under the control of a bubble memory controller. The initialization data is thereby erased after the new data is completely written in the first data storage area, after which the new data, written in the first data storage area, is again written into a second data storage area from the first record to the last record thereof.

    摘要: A method and apparatus used to compensate for thermal displacement and to correct a positional error caused by the thermally induced displacement of a spindle positioned in response to a numerical control system. The amount of thermally induced displacement of the spindle, at a predetermined point in time after application of electric power to the machine tool, is stored in a memory. When the spindle is to be positioned in response to numerical control data, the commanded amount of spindle movement is compensated by using the amount of thermally induced displacement stored in the memory, and the spindle is then positioned on the basis of the compensated commanded amount of movement.
