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： An acceleration/deceleration control apparatus according to the present invention is utilized in a numerical contorl unit in which a machine tool is provided with a machining program from a command tape (3) and the machining program is decoded to simultaneously control movement along a plurality of axes. In order to eliminate machining trajactory sag which occurs at the breaks between program blocks, the actual velocity of a controlled object during deceleration is compared with the commanded velocity in the next command data block by a comparator circuit (7). Until the actual velocity is less than the command velocity, a pulse distribution circuit (6) is stopped so as not to perform pulse distribution based on the next command data block. This improves the accuracy of position control by servomotors (1), (2) the acceleration/deceleration of which is controlled by interpolation data.

摘要： An involute interpolation method for a computerized numerical control apparatus having a rotational axis and a linear axis is effected by giving commands for a direction in which an involute curve (IC) rotates, the position of the center of a base circle (BC), and the radius (R) of the base circle, and interpolating the involute curve (IC) according to the commands. Interpolated distances are converted to those along the rotational axis and the linear axis for the control of a machine tool (9).

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.

摘要： A numerical control method is provided, which is capable of compensating for a response delay of a servo system to command pulses to thereby make it possible to repetitively effect reciprocal movement of a controlling object at a high speed over the entirety between target positions inclusive of these positions, without the need of increasing a time period for execution of a desired operation.A time period (T0) required for delivering all of the command pulses for forward movement is calculated on the basis of a commanded moving amount and a commanded feed rate (V0) stated in a program, and a corrected feed rate (V1) is calculated in dependence on the amount of command pulses for backward movement delivered over a time period (t2) starting at an instant (t1) that delivery of command pulses for backward movement is started and ending at an instant a positional deviation becomes zero, and further, the command pulses for forward movement and for backward movement are delivered over the time period (T0) at the corrected feed rate (V1), respectively.

The apparatus includes commander for synchronously issuing a standby command or standby-cancellation command to each system, and timing setting means for setting standby command timing or standby-cancellation command timing between systems brought into coincidence by the command means, wherein standby timing or standby-cancellation timing set with regard to the program of one specific system decides the timing of standby control by the program of another specific system. As a result, a system to be put on standby and a system to be released from standby can be designated at will to enable highly efficient control of the machine tool.

摘要： A numerical control system controls a plurality of axes with a plurality of channels (10, 20, 30). When a machining program for a first channel (10) is interrupted after a single block in response to a single block signal (6), the feeding of commands of a machining program for other channels (20, 30) is held. The machining programs are thereby executed in synchronism with each other. The machining processes are prevented from being unbalanced, and machining interference is avoided.

摘要： An involute interpolation method for use in machining by a numerical control apparatus.A rotational direction (G03.1) of an involute curve, coordinates of an end point (Xe, Ye), a center position (I, J) of a base circle as viewed from a start point, and a radius (R) of the base circle are instructed, from two equations representing the involute curve sequence of points are obtained, and interpolation of the involute curve is performed while interpolating those points in a range of the angle .theta. corresponding to the start point on the involute curve to the end point thereon.The increment of .theta. is decremented in proportion to the increment of the angle owing to the factor K/ (R.multidot..theta.), so that the interpolation is performed in such a manner that the speed in the tangential direction is made at constant, whereby a machining speed of the involute curve is maintained at constant.
