摘要： A numerical controller with a program resuming function of acquiring program-resuming block data with which a machining program is resumed without producing a scratch on a workpiece. It is determined whether there are registered non-cutting commands. Whether all the registered non-cutting commands are analyzed is determined. Data of registered non-cutting command is read, and whether a block currently being analyzed includes a non-cutting command is determined. It is determined whether or not the registered non-cutting command is one in accordance with which data is acquired at a block start point. Program-resuming block data is acquired at the block start point or at a block end point, the acquired data is stored into a memory, and a process is completed.

摘要： A numerical controller capable of shortening time required for transferring control of a spindle between different control systems. It is determined whether or not a spindle control command is included in a machining program for one control system. If the spindle control command is included, the command is carried out and information on designation of the spindle and commanded rotational velocity and direction is stored in a case of a velocity control mode, and information on designation of the spindle and commanded rotational position and velocity is stored in a case of a position control mode. When a command to cancel the control of spindle is read, the control of the designated spindle and also the stored information on the control status of the spindle are transferred to the other control system. A command to acquire the control of the spindle is read in a machining program for the other control system is read, the control of the designated spindle is started by the other control system according to the transferred control status of the spindle. The processing is performed for the programs for all the control systems.

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： A method of correcting a change of position of a machine tool having at least two control axes avoids abrupt machining errors. A position correction means (12) outputs correction pulses (Xcp, Ycp) so that the ratio of actual amounts of movement of the respective axes, obtained from the output values of position detectors (8X, 8Y) detecting a position of the machine tool, becomes equal to the ratio (R1) of distribution pulses (Xp1, Yp1) for the respective axes. The correction pulses (Xcp, Ycp) are added to the distribution pulses (Xp1, Yp1). Accordingly, an abrupt machining error caused at the beginning or just before the end of machining, or when machining a corner of a workpiece, is alleviated.

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： 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.
