    摘要： Ein Verfahren zum funkenerosiven Feinbearbeiten auf Drahtschneidemaschinen und eine funkenerosive Schneidevorrichtung ermöglichen Oberflächenqualitäten besser als Ra=0.1µm in Werkstattumgebung. Das mindestens einmal vorgeschnittene Werkstück (2) wird als Geometriereferenz für weitere Feinschnitte herangezogen. Es werden elektrische Spaltparameter und die Funkenverteilung über die Werkstückhöhe gemessen. Durch eine quer zur Schnittrichtung ausgeführte Feinservobewegung wird die Spaltweite optimal bis in den Submikrometerbereich geregelt. Dadurch wird es möglich, feinste Oberflächen auf einer normal genauen Maschine herzustellen.

    摘要： This invention relates to a method of preparing NC data for coreless machining in wire cut discharge machining using an automatic programming apparatus. A programming apparatus which reads the profile (C1) of a machining area (A1), a wire connecting position (PO) and a maximum cut-in quantity from a PERT program prepares NC data for moving a wire from the wire connecting position (PO) to a machining area center position (P1) (S1) while effecting discharge machining, determines a spiral tool orbit consisting of circular orbits (PS1 ∩ PS3) each having a shape similar to a figure expressing the profile of the machining area and spaced apart mutually by a maximum cut-in distance and linear orbits connecting the adjacent circular orbits with one another and prepares NC data for making rough machining along the linear orbits and circular orbits inside a finish machining area inner peripheral curve (C2) (S2). When the NC data for making final rough machining along the inner peripheral curve is produced (S3), the cut-in distance from the circular orbit (C3) adjacent to the inner peripheral curve is limited to the distance between them. Finally, NC data for making finish machining along finish machining orbits (C4, C5, C1) outside the inner peripheral curve determined on the basis of a finish margin and the number of finishes in the PERT program is prepared (S4).

    摘要： Bei dem beschriebenen Drahterodierverfahren, bei dem ein Formteil aus einem größeren Teil herausgetrennt wird, wird der Erodierdraht am Konturübergangspunkt zwischen zwei Konturelementen auf die Außenkonturlinie des herauszutrennenden Formteils ein- und ausgefahren. Hierdurch lassen sich Anbindungen vermeiden.

    摘要： A method of displaying machining shapes in a wire discharge machining apparatus which moves the work relative to a wire electrode, and which horizontally moves a guide by which the wire electrode is stretched to machine the work in a tapered manner. The method comprises a first step which receives a programmed passage (WDP) on the lower surface of the work, thickness of the work, tapered angle alphai of the blocks or either one of position deviation vectors (ui, vi) on the upper and lower surfaces of the work, and data that specified the number n of sectional shapes (S1, S2, ....., Si, .....) formed by cutting the tapered surface on a plane in parallel with the lower surface of the work; a second step for finding a wire electrode passage (WUP) on the upper surface of the work which is not the programmed surface by using the programmed passage (WDP), thickness of the work, and tapered angle or position deviation vector; a third step for finding coordinate values of points (Q1S, Q2S, ....; Q1e, Q2e, ....) of sectional shapes at the ends of the blocks using wire electrode passage data on the upper and lower surfaces of the work, and the number n of sectional shapes; and a fourth step which displays on a display unit the wire electrode passages (WUP, WDP) and sectional shapes (Si) of the tapered surface by using wire electrode passage data on the upper and lower surfaces of the works and coordinate values of points of sectional shapes at the ends of the blocks.

    摘要： A wire-cut taper machining method wherein the relative movement between a wire (WR) and a workpiece (WK) is controlled by effecting a simultaneous biaxial control for each of two control services (FCS, SCS), i.e., a simultaneous 4-axial control as a whole, thereby tapering the workpiece into a part of a predetermined configuration. The method comprises: a first step of inputting data containing at least data specifying the configuration of the upper and lower surfaces of the part; a second step of, when there is a distance between two surfaces in at least one of the pair of the upper surface (US) of the part and the first control surface (FCS), and the pair of the lower surface (DS) of the part and the second control surface (SCS), projecting corresponding points (P1, P2) of the upper and lower surfaces of the part specified by the configuration data onto the control surface of the pair which has the distance, along the straight line joining th points (P1, P2), thereby obtaining the positions of projection points (Qi, Ri); and a third step of effecting a simultaneous 4-axial control using the position data on the corresponding points on the first and second control surfaces so that the wire simultaneously follows the corresponding points along the first and second control surfaces.
