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 synchronous controller capable of gently changing a synchronous multiplying factor and setting the gentleness of changing of the synchronous multiplying factor without shocking a machine. A block for gently changing the synchronous multiplying factor is added between blocks before and after the changing of the synchronous multiplying factor. Synchronous multiplying factors a and b before and after changing of the synchronous multiplying factor designated in the added block, a motion amount p of master axis, a motion amount of a slave axis, and a residual motion amount v of the master axis after the completion of changing the synchronous multiplying factor (or a preliminary motion amount u of the master axis from the start of motion of the block concerned to a position for the start of changing of the synchronous multiplying factor) are read out. A gradient of changing the synchronous multiplying factor and the preliminary motion amount u (or the residual motion amount v) are obtained based on these data. The slave axis is controlled based on the motion amounts u and v and the gradient of changing the synchronous multiplying factor. The synchronous multiplying factor is changed so gently that the machine cannot be shocked. The synchronous multiplying factor gradient can be settled depending on the designated data p, q and v (or u).

摘要： An ‘interval’ in which the synchronization status between the movable axes subject to synchronous control is monitored, an equation between the movable axes in the ‘interval’, and an ‘allowable displacement’ for the positional relationship obtained with this equation and the actual positional relationship are set in advance. The ‘start condition’ and ‘termination condition’ for synchronous status verification processing are set with the master position and the like. When the start condition for synchronous status verification processing is satisfied, it is detected whether or not the actual position and the position obtained with the equation are within the range of the allowable displacement based on the position of the movable axes. If not within the range of the allowable displacement, operation set as ‘operation to be executed when the allowable displacement is exceeded’ is executed.

摘要： A synchronous controller capable of easily controlling a slave axis in synchronism with a master axis performing a composite motion of a plurality of axes. Motion commands for two axes X, Y constituting the master axis are subject to interpolation/distribution and acceleration/deceleration processing, to determine distribution motion amounts, and the determined amounts of motion of the two axes X, Y constituting the master axis for every interpolation period are combined to determine an amount of motion M of the master axis, from which is determined an amount of motion of the slave axis for every interpolation/distribution period. The determined amounts of motion of the X, Y and slave axes are output to respective servo control means, thus driving the respective axes. In case the master axis is constituted by a means driven by external X and Y axes, amounts of motion of the external X and Y axes for every predetermined period are detected by detectors, and used, instead of the distribution motion amount, to determine an amount of motion M of the master axis from which an amount of motion of the slave axis is determined to drive the slave axis.

摘要： An acceleration/deceleration method capable of synchronizing two axes in velocity and also in position is disclosed. A follower axis X continues to be accelerated after a velocity Vx of the follower axis X reaches a target velocity Vy of an objective axis Y and the acceleration is changed over to a deceleration to achieve the target velocity Vy. The time for changing over the acceleration to the deceleration is determined so that the motion amount of the position Px of the follower axis X in excess of the motion amount of the position Py of the objective axis Y is equal to the sum of the displaced motion amount in the acceleration motion and an initial positional difference. Thus, the position and velocity of the follower axis X coincide with the position and velocity of the objective axis Y to achieve complete synchronism of the two axes in the case where there is a positional difference and a velocity difference between the two axes.

摘要： In a master unit, clock signals from a clock are counted by a counter, and clock data is generated. This clock data is outputted to a slave unit by a driver, and stored in clock data storage memory. The slave unit stores clock data received by a receiver in the clock data storage memory. A processor for a program controller of the master and slave units starts up, and executes the synchronized operation of an operating program of axes that are synchronized on the basis of clock data stored in the clock data storage memory. It is also possible to commence operation of an axis under other conditions without relying on clock data. If override is applied to clock data, override will apply only to an axis that is synchronized and operated in accordance with clock data.

摘要： A single control unit in a multi-path synchronization system for a CNC controller simultaneously controls a plurality of paths. A program storage unit stores NC programs corresponding to respective paths. Those NC programs contains synchronization command codes which specify conditions of multi-path synchronization. A decoding unit decodes the NC programs for respective paths. Axis control unit controls the axes of a machine containing the paths by executing the decoded NC programs a in parallel. While executing the NC programs, synchronization control unit interlocks the motion of each axis according to the synchronization conditions specified by the synchronization command codes written in the NC programs.

摘要： A numerical control apparatus for adaptively controlling a servo apparatus, wherein a load current (Ln) and a velocity (Vn) of a spindle motor (74) are used as a fuzzy input. In response to the fuzzy input, a fuzzy control means (80) effects a fuzzy inference to output a velocity control signal (Cng) for controlling the velocity of the spindle motor (74). This control of the velocity of the spindle motor (74) with the velocity control signal (Cng) makes it possible to effect a smooth velocity control.

摘要： A position correcting system is incorporated in a machine tool having a plurality of workpiece machining positions. A control block (80) has a position correcting register (81) for storing position correctives corresponding to the respective workpiece machining positions. Distributed data (X1, Z1) are calculated from a machining program (71) by a pre-processing means (72). The position correctives (.DELTA.X1, .DELTA.Z1) are added to the distributed data (X1, Z1) by an adder (82), which outputs position commands for machining heads corresponding to the workpiece machining positions. In response to the position commands, an interpolating unit (83) carries out pulse interpolation and produce output pulses. Such control blocks (80, 90, 100) are associated with the respective machining heads. Errors between the workpieces and the machining heads are corrected in all the machining positions, so that the workpieces can be machined with accuracy.
