Abstract: A numerical controller having a learning control function executes commands in an NC program, starts performing learning control from a location where the same operation pattern starts occurring, and stops performing learning control at a location where the same operation pattern ends. Once a command that allows learning control is established in the NC program, the section in which learning control is carried out can be automatically determined.

Abstract: A machine having X- and Y-axis linear moving axes and a pivot axis B for rotationally pivoting a pivot member having a tool arranged at a distal end thereof about an axis parallel to a Z axis is controlled. A moving command obtained by a command program commanded by a position expressed by X, Y, and Z in a three-dimensional orthogonal coordinate system is subjected to an interpolation process to calculate amounts of interpolation movement (?X, ?Y, and ?Z) of the respective orthogonal axes. An amount of rotation ?? of the pivot axis required for moving the tool by the amount of movement ?Y in the Y-axis direction is calculated. An amount of correction movement ?x for canceling the movement in the X-axis direction caused by the rotation ?? of the pivot axis B is calculated. Values (?X+?x), ??, and ?Z are outputted to the X axis, the pivot axis B, and the Z axis, respectively.

Abstract: A superimposing control method using a numerical control device, capable of starting and terminating a superimposing control even during movement, without the need of waiting for the adjustment of timing and without rapid acceleration or deceleration. In response to a superimposition command, a motion value distributed to a Z axis of a superimposing axis in a reference system is subjected to acceleration/deceleration processing by an acceleration/deceleration processing section separately provided for superimposition, and the obtained movement value is added to a motion command value for a Z axis of a superimposed axis in a superimposing system. When a superimposition termination command is issued, the motion command value remained in the acceleration/deceleration processing section for superimposition is superimposed on the motion command value for the Z axis of the superimposing system. The superimposition can be smoothly started and terminated without the need to stop the two control systems.

Abstract: A numerical control method makes it possible to perform machining of a workpiece at a high speed with a desired accuracy. After start of pulse distribution, a determination is made as to whether or not both a block being executed and a next block of an NC program relate to a cutting command (steps S12 and S13). An in-position value (A, B), corresponding to the determination result, is then stored in a register (C). In the case of three control axes, when the deviations (.epsilon.x, .epsilon.y, .epsilon.z) between target moving amounts and actual moving amounts for the three control axes are less than the value stored in the register (C), positioning control for the present block is completed, and the execution for the next block is started (S10). This permits variable setting of the desired positioning accuracy to be carried out. The method is applicable for any number of control axes.

Abstract: An interfacing method in a numerical control apparatus is provided, which is capable of effecting, at a high speed, an interfacing process upon transfer of a signal between microprocessors respectively housed in a numerical control section and in a programmable machine controller. When reading out an M code from a numerical control program, the processor of the numerical control section delivers the M code to a latch circuit of an interface circuit so as to store the same code in the latch circuit, and inverts a logic level of a first status signal (MF) stored in a corresponding bit region of a first register of the interface circuit. Thereafter, when the controller completes a sequence control associated with the M code, the processor of the controller inverts a logic level of a second status signal (MFIN) stored in a corresponding bit region of a second register of the interface circuit.
