摘要： A system for reloading pitch error correction data at the time of replacing a movable part constituting part of a mechanical system of a numerically controlled machine tool. A command to reload the pitch error correction data is preset in a machining program at the time of replacing the movable part. A numerical control device reads this command. If a parameter reload command is given (S1), and if it is the pitch error correction data (S2), it is determined whether the movable part is situated at the original position (S3), and the pitch error correction data is automatically reloaded (S4). Accordingly, the operator is not required to carry out any operation related to the reloading of the pitch error correction data, and thus the machining can be effected with the use of correct pitch error correction data.

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： An acceleration/deceleration control method for a numerical control device (CNC) which subjects a command value of a velocity in a tangential direction of a traveling path, which is instructed by a pre-interpolation feed command, to an acceleration/deceleration control. A command is read (S1), and an angle .theta. of a traveling direction of a tool with respect to an X axis is calculated (S2). Tangential accelerations .alpha.vx and .alpha.vy are derived based on preset maximum permissible accelerations for individual axes and the angle .theta. (S3). A smaller of the tangential accelerations .alpha.vx and .alpha.vy is set as a tangential acceleration .alpha.v (S4). The command velocity F is subjected to the acceleration/deceleration control by using the acceleration .alpha.v (S5), and then the interpolation is effected (S6). Since the tangential acceleration .alpha.v is set to a maximum value in a range in which the accelerations of the individual axes will not exceed the maximum permissible values thereof, the time required for effecting the acceleration/deceleration control can be reduced to a minimum value.

摘要： Disclosed is a numerical control apparatus for controlling a chopping operation of a tool used in a grinding machine and the like. A programmed instruction value calculation circuit (2) outputs an upper dead point instruction (Zu) and a lower dead point instruction (Zl), a correction value calculation circuit (3) calculates and outputs correction values (.DELTA.Zu, .DELTA.Zl), and a chopping instruction calculation circuit (4) outputs a chopping control output to a manual control circuit (6) based on these instructions and correction values to operate a servo motor. When an instruction value (Zi) is input from a manual pulse generator (5) to the chopping instruction calculation circuit (4), the chopping is effected while continuously changing the upper and lower dead points, thereby enabling an operator to easily adjust the upper and lower dead points.

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 feed speed control method for a numerical control device in which a feed speed of a tool traveling along an instructed machining path is controlled in accordance with a machining program. The speed of each axis is derived (S2), and the acceleration of each axis is derived from a speed variation between adjacent blocks (S3). When the acceleration (.DELTA.Vx) is larger than a permissible acceleration (.DELTA.Vxmax) (S4), first ratios (K1) of the permissible accelerations to the accelerations are derived for individual axes (S5), and the smallest of the first ratios is selected. The command speed is multiplied by the square root of the smallest first ratio to derive an actual feed speed (S9). In this way, shock to a machine is reduced and an excessive load on a servomotor is reduced even when blocks continue for successive infinitesimal distribution distances, as in the case wherein a curve is approximated by the use of straight lines.
