摘要： A controller for a machine tool, capable of performing ultraprecision machining with high accuracy by performing correction allowing for a displacement of a spindle produced depending on a rotational speed. When the spindle is rotated at high speed, the cutting position of a tool attached to the spindle varies due to the influence of spindle fitting accuracy and of weight balance. By measuring the displacements in the X, Y and Z directions of the end of the tool attached to the spindle by means of non-contact displacement gauges, correction amounts are obtained in the manner associated with the rotational speed of the spindle, and stored in a storage device. In the process of machining, correction amounts are read depending on the speed of the spindle, and machining is performed according to program command values corrected using the correction amounts thus read. Even if the cutting position of the tool varies during high-speed rotation, machining is performed according to program command values corrected. Thus, ultraprecision machining can be carried out with high accuracy.

摘要： A material testing machine includes a control system which, during material testing, feedback-controls the operation of a servo system which includes an actuator for applying a load to a test piece, such that the actual load applied to the test piece coincides with the target load. The testing machine includes a waveform generator for generating a testing waveform indicative of the target load. The waveform generator includes a waveform data memory which stores therein a series of basic signal values sampled from a basic waveform so as to pick up a characteristic of the basic waveform. During the material testing, each of the basic signal values is repeatedly read out from the data memory, whereby the testing waveform indicating the target load is generated based on these basic signal values. An error between the controlled variable and the target load is determined based on peak and bottom values of the controlled variable, and the target load is corrected in accordance with the determined error, to thereby improve the responsiveness of the servo system.

摘要： The invention relates to a tracking detection system of electrical servomotors with incremental position detection in particular for servomotors in motor vehicles. To determine the position, said tracking detection system is provided with a microcontroller with an autoalarm device. Said microcontroller can be moved from run mode (B1) to sleep mode (B0) to reduce the average current intake, and after a predetermined period of time (e.g. 1 mm) can be automatically moved back to run mode (B1). Said microcontroller samples the position signals (HS) of position transmitter when it is in run mode (B1) at particular sampling points (11, 12), and is move between the required sampling points for a particular, calculated period of time in sleep mode (B0). The particular, calculated period of time is calculated from a detected edge change of the position signal.

摘要： A tracing control system machines a workpiece to a desired contour corresponding to the surface of a model which is being traced. The tracing control system comprises a tracing control circuit, a digitizing circuit, and numerical circuits. The tracing control circuit controls a plurality of tracing axes to trace the surface of the model. The digitizing circuit is connected to the tracing control circuit through a bus, for reading the positions of the tracing axes as positional data from time to time and processing the positional data to prevent a cutter head from biting into the workpiece, thereby to generate NC data linearly approximate the surface of the model. The numerical control circuits are connected to the digitizing circuit through the bus, for positionally controlling as many machining axes as the number of the tracing axes on the NC data to machine the workpiece.

摘要： A technique for overcoming the difficulties that arise from the transition between coarse and fine loop control. Coarse and fine phase locked loops, each having a respective latch provide a coarse number in the range 000.0.degree.-359.9.degree. and a fine number in the range of 0.0000.degree.-0.9999.degree.. The coarse number is offset relative to the fine number so that the least significant digit (tenths digit) of the coarse number is always less than the most significant digit (tenths digit) of the fine number over the entire range of motion. The fine number latch is clocked by a reference clock (ZDS) while correlation circuitry provides a clock signal for the coarse number latch. The correlation circuitry generates the clock signal when the tenths digit of the coarse number agrees with the latched fine number. The result is a latched fine number and a coarse number that is latched when it correlates with the fine number (tenths digits agree). A fine error is provided by comparing the fine PLL counter data against the fine angle command data. A correlated coarse error is produced by comparing the coarse command and the correlated coarse number (subtracting and scaling). The fine error and the correlated coarse error are communicated to the two poles of an analog switch, and the fine error is selected whenever the correlated coarse error is less than a predetermined threshold.

摘要： In a system for controlling or monitoring an object, wherein a position of the object must be determined, the system includes a first and second multispeed sensor, the first sensor having a speed of N and the second sensor having a speed of N-1. A method for determining the position of the object comprises the steps of obtaining position data as measured by the first and second multispeed sensor, respectively. A parameter, N.sub.A, a weighted difference between the obtained position data, is determined to ascertain whether a first or second case exists. If the first case exists, a first set of constants based on a first set of equations is generated; otherwise the first set of constants is generated based on a second set of equations. A second set of constants is then generated. Finally, the position of the object is determined by calculating the weighted average of the second constants, thereby obtaining the position of the object, utilizing the data provided by both sensors.
