摘要： A feed rate and positioning control system for a machine tool is described which utilizes an electro-hydraulic pulse motor to move a grinding wheel support at preselected rates and for predetermined distances during a grinding operation. A control counter is arranged, via rate selecting switches, to select pulses of various predetermined pulse repetition rates for controlling the rates at which the electro-hydraulic pulse motor moves during a grinding operation. End point selecting switches and comparators are provided for determining the distances moved by the support during a grinding operation to signal the control counter to change rates or to start a dwell period. Dwell selecting switches, responsive to the control counter, are provided to establish the duration of dwell periods between application of selected rates and to signal the control counter at the end of each dwell period, including a spark out period at the end of the grinding operation.

摘要： During movement of a machine table, pulses of fixed repetition frequency are counted to be converted to a phase angle which is, in turn, compared with a phase angle corresponding to the movement of the movable table until a difference between them reaches zero. The pulses are also counted by a position counter to decrease a digital value registered in it. As the counter decreases in value the table automatically switches its speed from a high to a moderate magnitude and then to a low speed when the counter clears the table stops at it command position. Also, after having reached a predetermined distance from the command position, the table can progressively decelerate in accordance with the value remaining in the counter.

摘要： An electronically operated automatic control for machine tools is described wherein the tool or movable member is transversely movable toward and away from a stationary member, which might be a workpiece or tool holder. The movable member is driven by a stepping motor. Pulses are supplied to the motor for powering same. A pulse counter is provided so that the amount of movement of the motor is controlled by the counter. The counter can be set to zero for any position of the moveable member, so that all displacements of the movable member are measured by the counter beginning at the latter position, where the counter was set to zero.

摘要： Disclosed is a stepping motor control utilizing a microprocessor. The control is suitable for driving one or more stepping motors one at a time or in unison. In the illustrated embodiment when plural motors are driven together they are driven at the same rate or at rates in a fixed proportion to one another although several of the features of the invention are suitable for use in circuits providing contouring control; i.e., where separate motors are driven at separate stepping rates proportional to the relative distances each is to traverse for a single movement. An acceleration/deceleration circuit is utilized which provides simple yet highly accurate and efficient control of the stepping motors. Feed rate compensation for simultaneous drive of two motors is provided. Also a means is provided to allow stepping rates in excess of the counting rate capability of the microprocessor.

摘要： A pulse train conversion system includes a binary counter having a plurality of stages which store a count, the count being advanced in response to a clock pulse. The counter stages are respectively connected to counter inputs of a logic circuit, digital value inputs of the logic circuit being connected to registers having a plurality of stages. The logic circuit provides an output pulse in response to the output of a particular stage of the counter being false and outputs of all stages of the counter of lesser significance than the particular stage being true concurrently with a stage of the register, corresponding to the particular stage of the counter, being true.

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： An apparatus for producing relative movement between a work surface and a surface modifying mechanism in two independently controllable component directions. An energizing circuit generates a predetermined path of relative movement in response to objective data input. By independently varying the velocity magnitudes of the components of relative movement, the energizing circuit insures the generation of a smooth travel path that is desirable for high quality surfaces.
