摘要： A multi-axis machine tool or the like employing controls for an open loop stepping motor system of two or more axes in which variable frequency feedrate clock pulses are generated to ultimately control the speed of the various stepping motors. The frequency of the feedrate clock pulses is modified in accordance with programmed information; additional information defines the tool path which can either be straight line or circular arc segments and characteristically the feedrate clock pulse generation means increases pulse frequency at the beginning of a segment in such manner as to increase motor speed in accordance with system inertial limitations from a speed below to a speed above the slewing rate of the stepping motors. Thereafter upon sensing a predetermined distance from the end of the segment, pulse frequency is reduced to reduce the stepping motor speed below the slewing rate. The feedrate clock pulse chain is used by the interpolation logic to trigger two consecutive calculations, the time lapse between the clock pulse and the second calculation being so short compared to the time lapse between consecutive clock pulses, that the action initiated by the results of the calculations can be considered for all intents and purposes to be coincident with the clock pulse. The first calculation always generates a major axis interpolation pulse, during the second calculation an error accumulation register is tested to determine whether a minor axis interpolation pulse should be generated to minimize the error from the programmed path. Thus the major axis interpolation pulse chain corresponds directly to the frequency of the feedrate clock chain, the minor axis interpolation pulse chain may be irregular with respect to the chain of feedrate clock pulses. A predetermined member of interpolation pulses are then used to generate each of the major and minor axis step pulses so that any irregularity in minor axis pulse frequency is eliminated and resolution is improved.

摘要： The output from a control means providing pulses representative of English system units is applied to a countermeans, which, as it counts the input pulses applies the count as an output to a memory means. The memory means contains storage locations corresponding to permissible counts of counter to provide a pattern of predetermined fixed relationship between the English and Metric system, such that for each input count a predetermined output in terms of Metric measurement is provided. The memory system also provides means for adjusting the count in the counter and specifically, depending upon the direction of counting, readjusts the counter to zero upon completion of a predetermined number of steps in a repeatable pattern and when counting down skips the counter to the last predetermined count of a finite number of steps in said pattern.

摘要： An economical rotary index table holds workpieces on machine tool beds and tables, changing rotational position in angular increments with precision. Accurate angular indexing is achieved by a curvic coupling with meshing radial teeth disengageably connecting an axially movable locking plate to the juxtaposed facing rotational worktable member, separate and apart from the drive system. An annular, axially expansible pneumatic chamber is employed to engage and disengage the curvic coupling teeth, alternately locking the worktable in the desired angular orientation, and unlocking it for angular indexing movement. In the preferred embodiment, the movable angular indexing apparatus of the present invention incorporates automatic counting means for precisely determining the degree of rotation and automatic stop means for preventing further rotation when the desired position has been reached.

摘要： In a conventional machine tool wherein a spindle is mounted within and rotatable relative to a quill, which in turn is supported on a housing frame for relative axial movement, a nut is provided coaxially surrounding the quill and having helical threaded engagement therewith. Driving actuator means supported on the frame operates on the nut and quill combination to rotatably move one member of the combination relative to the other to produce linear axial movement of the quill and spindle relative to the frame.
