摘要： An involute interpolation method is provided for machining operations in a numerical control apparatus, in which a rotational direction of an involute curve, a center position of a base circle (C), and a radius (R) of the base circle (C) are instructed, and an interpolation is performed with respect to an involute curve having a start point (P.sub.s) on a first involute curve (IC1) and an end point (P.sub.e) on a second involute curve (IC2). According to such a method, machining operations can be done by the use of a specifically configured involute curve which is distinct from the two involute curves.

摘要： A switch-type reluctance motor and method to compensate for counter electromotive force. The switch-type reluctance motor includes an actual current detection unit to detect the actual current i of the motor or an electrical angle detection unit to detect the rotor electrical angle .theta., a rotation rate detection unit to detect the rotor rotation rate and a counter electromotive force compensation unit to calculate a counter electromotive force compensation value based upon at least one of the actual current and the electrical angle, as well as the rotation rate. A voltage command is compensated with the calculated counter electromotive force compensation value Vc. Thus, counter electromotive force compensation corresponding to changes in the electrical angle .theta. and/or the current i is performed for the switch-type reluctance motor.

摘要： An acceleration/deceleration control apparatus for a numerical control apparatus which controls a tool in a vicinity of a stroke end by making maximum use of a stroke. The tool moves along a locus in an in-stroke region surrounded by a stroke end and carries out machining of a workpiece such as cutting and the like. The tool, which is moved by the numerical control apparatus according to a machining program, starts from a start point and moves up to an end point in accordance with preread machining blocks. The tool moves in response to usual feed speed control except that tool feed speed is decelerated in sections of the machining blocks when the tool approaches the stroke end. The tool feed speed is controlled to a minute speed just before the tool reaches the boundary of the stroke end and maintains the minute speed while moving along the stroke end. The tool is then accelerated after moving from the stroke end and returns to usual feed speed control.

摘要： Disclosed is a numerical control apparatus for controlling a numerically controlled machine tool such as a hobbing machine and the like. An axis control circuit (14) provided with a synchronization control means (8) controls the rpm of a spindle motor (5) and the rpm of a servo motor (11) based on feedback pulses supplied from a position coder (7) connected to a hob axis (3), so that a ratio of the rpm of the hob axis (3) to the rpm of a C-axis (13) has a given value. A first internal counter (15a) monitors the number of feedback pulses supplied from the position coder (7) and a second internal counter (15b) monitors the number of pulses distributed to the C-axis (13), and when a ratio of the rpm of the hob axis (3) to the rpm of the C-axis (13) is to be changed, a correction pulse calculation means (9) calculates correction pulses based on the number of rotation pulses of the hob axis (3) and the number of the rotation pulses of the C-axis (13) counted by the first and second internal counters (15a, 15b). The correction pulses are supplied to the C-axis (13) to accelerate or decelerate the rpm of the C-axis (13) and thereby achieve a new synchronous relationship between the hob axis (3) and the C-axis (13) during the rotation of the hob axis (3) and C-axis (13).

摘要： A method of correcting a change of position of a machine tool having at least two control axes. A position change check simulator (14) obtains a ratio (R2) of amounts of movement of respective axes (Xe1, Ye1) obtained from output values of position detectors (8X, 8Y) for detecting a position of the machine tool, and further, obtains a ratio (R1) of predicted amounts of movement of the respective axes obtained from a machine position predicted on the basis of distribution pulses (Xp5, Yp5) of the respective axes, assuming that a servo system has a first order lag. A position correcting means (12) outputs a correction pulse (Xc1, Yc1) so that the ratio (R2) of actual amounts of movement becomes equal to the ratio (R1) of the predicted amounts of movement. This correction pulse (Xc1, Yc1) is added to command pulses (Xp1, Yp1), and accordingly, an abrupt machining error occurring at the beginning and just before the end of machining, and during the machining at corners of a machined article, can be eliminated.

摘要： Provided is a numerical control method in an apparatus having a C-axis control function for numerically controlling a spindle in the direction of rotation. The method includes providing a first G-code word (Gg1) for achieving agreement between axis control characteristic values of a C-axis motor control system and axis control characteristic values of a feed-axis motor control system, as well as a second G-code word (Gg2) for restoring axis control characteristic values changed by the first G-code word to original values, making spindle control characteristic values agree by commanding the first G-code word before controlling the C axis at the same time as the feed axis, and restoring to original values the spindle control characteristic values changed by the first G-code word by commanding the second G-code word after simultaneous control of the C axis and feed axis ends.

摘要： An involute interpolation method for machining operations is used in a numerical control apparatus.A rotational direction (G03.1) of an involute curve, an incremental distance along the involute curve or an incremental angle, a center position (X.sub.0, Y.sub.0) of a base circle and a radius (R) of the base circle are obtained per the instruction. The involute curve is interpolated using a predetermined distance or predetermined angle.The above processing is executed with a numerical control apparatus and pulse distributions are continuously carried out. Therefore, the involute curve can be interpolated without need for a special program producing system.
