摘要： A pitch error compensating system compensates for a pitch error of a ball screw of a numerically controlled machine tool. A pitch error calculating means (4) reads a present value from a present value register (3), reads pitch error corrective quantities (.epsilon.n, .epsilon.pn) in a corresponding period, and outputs pitch error corrective quantities as pitch error corrective pulses (CP) at equal intervals in the period. The pitch error corrective pulses (CP) are added to interpolated pulses (CP) by an adder (5). Since the pitch error corrective quantities are not outputted all at once, the machine tool moves smoothly, and the quality of the machined surface of the workpiece is improved.

摘要： A gear pitch error correcting system for a numerical control apparatus used for a machine tool including at least one pair of gears provided in a transmission line through which the rotating force of a servomotor is transmitted to a driven member. Gear pitch error correction values for the respective gears, which each correspond to a predetermined gear angle and collectively cover one gear rotation, are stored in a nonvolatile memory. A pitch error computing means (E) refers to a current position register (D), reads out pitch error correction data (14b) corresponding to the current position from the nonvolatile memory, and adds up the data to obtain a superimposed pitch error correction value. The superimposed pitch error correction value and an interpolation pulse from an interpolating means (B) are added together by an adder (C), to obtain a pitch error-corrected output pulse, which is then supplied to an axis control circuit (18). Accordingly, even with a relatively small number of gear pitch error correction values for the individual gears, a gear pitch error correction can be precisely executed in proportion to the superimposing of the gear pitch error correction values.

摘要： When a numerical controller executes a tool-center-point control in which a path of a tool center point with respect to a workpiece is instructed, and the workpiece is machined along the instructed path based on a speed instruction, the numerical controller sets the speed instruction so that the speed instruction is a synthesis speed with respect to a synthesis distance of a relative moving distance between the workpiece and a tool center point and a tool-direction changing distance due to a relative change in a tool direction with respect to the workpiece by a rotary axis. The numerical controller interpolates a position of a linear axis and a position of a rotary axis by the tool-center-point control according to the synthesis speed and drives the linear axis and the rotary axis to the position of the linear axis and the position of the rotary axis created by the interpolation.

摘要： A controller for a machine capable of performing acceleration/deceleration control to which an optimal tangential acceleration within an allowable maximum acceleration for each axis is applied. A first interpolation section receives data obtained by analysis of a program by a command analysis section, an makes interpolating calculation in every first sampling period to output it into an intermediate memory. A tangential acceleration calculating section determines a tangential acceleration based on each segment and the allowable maximum acceleration for each axis to output it into the intermediate memory. A deceleration target velocity calculating section prepares an acceleration/deceleration pattern for a plurality of segments stored in the intermediate memory, to output it to the intermediate memory. An acceleration/deceleration control section performs acceleration/deceleration control based on the data in the intermediate memory so that the tangential velocity at an end point of each segment is not higher than the deceleration target velocity, and calculates velocity for each second sampling period. A second interpolation section defines a smooth curve based on the output from the acceleration/deceleration control section and the data taken out from the intermediate memory, and outputs a point on the smooth curve for each second sampling period.

摘要： A moving path for which an interpolation instruction is given is a free curve expressed by a vector P(k). This curve is divided at predetermined cycles, and tangential vectors P' (k.sub.1) and P' (k.sub.2) at the start point and end point of each divided block are calculated. From these data and an instructed velocity F, an acceleration vector in the corresponding block is calculated. If each axial component of the calculated acceleration vector exceeds an acceleration limiting value set for each axis in advance, the instructed velocity F for the block is lowered to a value at which the axial component does not exceed the acceleration limiting value.

摘要： A three-dimensional cutter compensation system provides cutter compensation for machining a workpiece with a cutter having a round edge and an axis which is tiltable in any optional direction in three-dimensional space. The three-dimensional cutter compensation system includes a cutter direction vector calculating unit for calculating a cutter direction vector from present position control axes. The control axes control the tilt of the cutter. A cutter offset memory stores a radius of the cutter and a radius of an arc of the edge of the cutter while a programmed path calculating unit calculates a programmed path commanded by a machining program. A cutter compensation vector calculating unit calculates a cutter compensation vector from the cutter direction vector, the radius of the cutter and the radius of the arc of the edge of the cutter, and the programmed path. The cutter is then shifted in response to the cutter compensation vector.

摘要： Equipment for a numerical controller is provided, for measuring the distance of travel of a tool through utilization of a skip function of a numerical controller and reducing a delay in detecting a skip signal thereby ensuring high precision measurement of the distance of travel. Position storage memory accumulates distribution command values, which are generated within a predetermined period, and second storage memory stores a stored value P.sub.0 of the position storage memory directly before the execution of a distance measurement function code. A time counter is counted up by pulses which have a period shorter than the predetermined period and are applied thereto from a pulse generator, via a gate circuit, wherein the time counter is cleared within the predetermined period. Upon input of the skip signal, the gate circuit stops the supply of the pulses to the time counter. A first operating system obtains a difference P between an accumulated value A, of the position storage means at the instant of input of the skip signal, and the stored value P.sub.0 in the position storage memory. Based upon the count value .beta. of the time counter at the instant of input of the skip signal, the maximum count value .gamma. of the time counter in the predetermined period, a variation .alpha. in the stored value of the position storage memory during the predetermined period, and the difference P. A second operating system obtains an amount of travel P.sub.n, from the instant of the start of travel by the skip function, to the instant of input of the skip signal.

The interface unit includes an actual speed memory (50) into which the numerical controller (NC) can write actual speed data and from which the electric power control circuit (PC) can read out the written data, and a corrected speed memory (51) into which the electric power control circuit (PC) can write corrected speed data and from which the numerical controller (NC) can read out the written data. This makes it possible for the electric power control circuit (PC) to detect the actual speed of the numerical controller (NC) by reading out the actual speed memory (50), and to control the actual speed of the numerical controller (NC) by writing the corrected speed data in the corrected speed memory (51).
