摘要： This invention relates to a digitizing method which digitizes model surface data by profiling a model (MDL) by a stylus (STL). When digitization is to be made, a time (T) required till predetermined conditions are established and a stylus moving distance (ΔL) during this time are monitored so as to determine a profiling speed (F) from the time and the moving distance. The profiling speed is outputted along with the model surface shape data.

摘要： A copying-speed control method for an NTC copying which performs profile control of one axis and numerical control of the other two axes. In the servo loop of the numerical control axis, an override control circuit (23) is provided between an error counter (22) and a D/A converter (16x). When a displacement changes abruptly the override value of the override control circuit is changed to stop or reduce the servomotor output of an error quantity in the error counter (22). Thereby, the biting at sudden changing parts of a model is reduced.

摘要： This invention relates to a profile control device that performs profile machining of a work copying a model surface. A profile control device (1) includes a profile control circuit (13), a digitizing circuit (16), and numerical control circuits (11, 18x, 18y, 18z). The profile control circuit (13) controls multiple profiling shafts (40x, 40y, 40z) to copy a model surface (43). The digitizing circuit (16) connected with the profile control circuit (13) via a bus acquires the positions of the multiple profiling shafts (40x, 40y, 40z) from one minute to the next as position data, and also performs the prescribed data processing to prevent the intrusion phenomenon and generates NC data that are linearly approximated to the model surface (43). The numerical control circuits (11, 18x, 18y, 18z) are connected with the digitizing circuit (16) via the bus (10), and control the positions of as many machining shafts (60x, 60y, 60z) as the number of the multiple profiling shafts (40x, 40y, 40z) based on the NC data and perform the machining of a work (63).

摘要： A tracer head (TC) is constituted so as to be rotatable in a rotating direction permitted by its rotating axis which is in parallel with an axis not constituting a profile plane (e.g. Y-axis) and when a recess (HL) having a vertical inclined portion (SL) is profiled, the tracer head (TC) is rotated so as not to interfere with a model (MDL) and the rotating angle (beta) in the rotating direction is monitored in order to correct the displacement quantity (ex, ez) of each axis in the directions of two axes (X, Z axes) other than the rotating axis on the basis of the rotating angle (beta). Profile control is made by use of each axis displacement quantity obtained by the correction.

摘要： The machining apparatus comprises a profile machining controller (1), and NC machining controller (2), and switching circuits (3X, 3Y, 3Z) which selectively transfer, depending upon select signals, the control instruction from said profile machining controller (1) and said NC machining controller (2) to a three-axis driver (4) on the side of profile machining and to a three-axis driver (5) ont he side of NC machining. Here, the select signals include a profile machining select signal (SA), an NC machining select signal (SB), and an NC-and-profile machining select signal (SC). When the NC-and-profile machining select signal (SC) is selected, the three-axis driver (4) on the side of profile machining is controlled by the profile machining controller (1) and the three-axis driver (5) on the side of NC machining is controlled by the NC machining controller (2) independently of each other. Therefore, the preparatory work for profile machining is effected or numerical data for profile machining are obtained while the NC machining is being carried out.

摘要： When a stylus (1) is long, the proportional relation between an actual quantity x of displacement and a quantity y of displacement detected by a tracer head (2) is lost, so that an accurate profile control operation cannot be carried out. Therefore, when a long stylus is used, the detected quantity y of displacement is corrected by using a correction function f(x) which is determined in advance, to determine a corrected quantity y' of displacement which is proportional to the actual quantity x of displacement, a profile control operation being carried out on the basis of the corrected quantity y' of displacement thus obtained.

摘要： A profile control method by which a work is machined by profiling a model with a tracer head. Two axes (X, Y axes) NC-instruct an instruction path and a speed, and three axes (X, Y, Z axes) make profile control. An NC instruction speed is changed by an override circuit (2b) so that the NC instruction speed (F) is in conformity with a combined speed of the three axes by the profile control, and as a speed Fd is sent to an interpolator (2a). The path by the two axes serves as an NC instruction path, the speed acts as profile control speed and they provide a motion which is equivalent to the profile control path by the three axes.

摘要： A profile control device for a rotating body, in which profiling is performed while rotating a model and a work. A plurality of point coordinates (P1 ∩ P10) to be determined by positions on the center axis of rotation and rotation angles of the rotating shaft are set on the outer periphery of the model (6) and profiling is performed on the basis of electric potential lines connecting a plurality of points (P1 ∩ P5, P6 ∩ P10) to each other. Hence, even when profiling of a model having a shape varying along the center axis of the rotating body, such as a groove in a cylindrical cam, is performed, the time taken for profiling can be reduced by encircling only a groove zone with the electric potential lines for defining, whereby the groove only can be profiled with high precision.

摘要： A profile control apparatus which prevents overcutting by a cutter at a corner portion by moving a tracer head ahead of the cutter. A first delay speed instruction Vxm or Vzm is determined by a first delay circuit (14a or 14c) having a time constant and a second delay speed instruction is determined by a second delay circuit (14b or 14d) having a time constant different from that of the first delay circuit for each speed instruction Vx, Vz for each axis determined on the basis of the displacement quantity εx, εy, εz in the direction of each axis detected by the tracer head, and the difference Vxs or Vzs between the first and second delay speed instructions is calculated. An X-axis main motor and a Z-axis main motor are driven by the first delay speed instructions to operate the machine as a whole, and an X-axis sub-motor and a Z-axis sub-motor are driven by the differences in parallel with the movement described above so as to move only the tracer head and thereby to move the tracer head ahead of the cutter.
