摘要： A numerical controller capable of shortening time required for transferring control of a spindle between different control systems. It is determined whether or not a spindle control command is included in a machining program for one control system. If the spindle control command is included, the command is carried out and information on designation of the spindle and commanded rotational velocity and direction is stored in a case of a velocity control mode, and information on designation of the spindle and commanded rotational position and velocity is stored in a case of a position control mode. When a command to cancel the control of spindle is read, the control of the designated spindle and also the stored information on the control status of the spindle are transferred to the other control system. A command to acquire the control of the spindle is read in a machining program for the other control system is read, the control of the designated spindle is started by the other control system according to the transferred control status of the spindle. The processing is performed for the programs for all the control systems.

摘要： A numeric array of move command data Qi constituting a reference cam diagram F (.theta.) is stored in advance in a data table of a CMOS memory. Alternatively, a shift position of a cam corresponding to a rotational angle .theta. of the cam is stored in advance so that move command data can be generated by obtaining the shift position of the cam from the rotational angle of the cam based on the rotational angle value. In response to the input of a shift Ka in the lift direction, shift Kb in the pitch-circle direction, maximum lift Kc, and data number n as a criterion for extension or compression in the pitch-circle direction, the move command data can be corrected by automatic processing by means of a motion controller. Thus, final move command data Pk can be generated and outputted as position commands.

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： Die cushion control device that implements die cushion control while making a switch between position control and pressure control by using servomotors, and reduces the impact caused by a collision between a press axis and a die cushion axis during position control. Die cushion members are controlled by servomotors Md. The changeover switch is connected to the “a”-side, to thereby control the position (velocity) of the servomotors Md by commands from a numerical controller and control the position of the die cushion members. During position control, the output torque of the servomotors Md is limited by torque limit means. During position control, even if the press axis hits the die cushion members due to erroneous setting, wrong operation or the like, the servomotors Md merely output only a limited torque or less, so that impact force is reduced, which prevents damage to the die cushion members and the press axis. During press operation, when a position detector detects that the press axis moves downward to reach a predetermined position, the changeover switch is connected to the “b”-side, to thereby implement pressure control.

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 method of and apparatus for synchronous control of a leading element and a follower element in which synchronism is started smoothly and a mechanical shock at the start of synchronism is reduced. When the follower element is started to move to be synchronized with the leading element, motion of the follower element is started before the follower element reaches a start position of the synchronism, and brought into synchronism with the leading element at the start position of synchronism. A positional relationship between the leading element and the follower element in synchronism, and a start position for starting the synchronism of the follower element and the leading element is set. An acceleration control of the follower element is performed between a motion start position preceding the start position of the synchronism and the start position of the synchronism. A position control of the follower element is performed based on position data of the leading element and the set positional relationship after the follower element reaches the start position of the synchronism.

摘要： A reference variable having a linear relationship with the angular position of a master axis is set, and a correspondence between this reference variable and the displacement of a slave axis is stored in a data table. One execution stage is specified by setting a starting reference variable and an ending reference variable from this data table. A desired sequence is assigned to a plurality of execution stages thus specified. The reference variable corresponding to the angular position of the master axis is determined, slave axis displacement data corresponding to the reference variable is read out, and the slave axis is positioned in accordance with the position of the master axis on the basis of this displacement data.
