摘要： A spindle is subjected to speed control and contour control according to a path table in which the speed and the position of the spindle are stored in association with a time. A switchover command for starting a contour control during speed control and a time La at which the switchover is carried out are set in advance in the path table. When the time La is reached, a spindle speed Sa and a spindle position Xa corresponding to the time La are read. Then, a time Lb and a spindle position Xb for the start of the contour control, designated next, are read. A speed is obtained from the spindle speed Sa and a speed in a first path in the contour control so that the spindle position shifts from Xa to Xb in a period between the times La and Lb. The spindle is moved from the time La to the time Lb at the obtained speed according to a designated linear function.

摘要： A memory other than a non-volatile memory in a numerical controller is divided into a plurality of memory areas in response to a command from a computer connected to the numerical controller. Whether a machining program has been stored in each of the divided memory areas is decided before a machining program stored on a hard disk in the computer is transferred to the memory other than the non-volatile memory. The machining program stored on the hard disk is then written to an area for which it is determined that no machining program is stored.

摘要： A numerical controller capable of avoiding a shock to a machine by a controlled axis when a command of an alarm, a reset or a feed hold is issued in a path table operation. The numerical controller performs the path table operation where position of a controlled axis of a machine is controlled in synchronism with an input value of a reference variable indicative of time, a position of an axis or a position of a spindle according to a data table that stores command positions of the controlled axis respective for set values of the reference variable. The numerical controller comprises deceleration/stop command receiving means that receives a command to decelerate and stop the controlled axis in the path table operation; and decelerating means that gradually reduces a rate of increase of the reference variable to zero so that the controlled axis is decelerated and stopped in response to the deceleration/stop command.

摘要： A numerical controller that enables an operation according to the path table in a plurality of systems individually or synchronously, the controller in which during a path-table operation in one system, it is possible to perform the path-table operation and the operation by NC statements in another system. The systems have their respective reference variables. There is provided means for switching whether the reference variable is set common or specific to each of the systems. It is possible, during the path-table operation in one system, to command the path-table operation of another system to start the path-table operation of the system, and to perform the path-table operation after waiting for the systems. If the reference variable is set common, path-table operations can be performed synchronously according to the identical reference. If the reference variable is set specific to each of the systems, path-table operations can be performed in the systems individually.

摘要： A numerical controller capable of operating an auxiliary function at a target time or spindle position in performing operation based on table format data. An auxiliary function table is stored with auxiliary function commands M to be outputted corresponding to commanded reference times Lc and their corresponding operation delay times D. A reference time L is updated based in accordance with an override value. An auxiliary function command M and its corresponding operation delay time D are read from the auxiliary function table. The delay time D is corrected with the override value, and a reference time prior to a commanded reference time Lc by a margin equivalent to the corrected delay time is set as a command time Lr. If an override is entered, the delay time is corrected for the override amount and modified into an overridden reference time unit, and a command time for an auxiliary function is obtained and outputted based on the reference time unit. Thus, the auxiliary function is performed appropriately at a commanded value Lc of the reference time.

摘要： A numerical controller which, after once stopping a slave axis during superposing control, can easily resume the superposing control. In the superposing control, a motion amount for a master axis and a motion amount for the slave axis are added to a workpiece coordinate value of the master axis and a workpiece coordinate value of the slave axis, respectively, to update their present position data (I2, II2). These motion amounts are supplied also to servo processing (I3, II3) for the master axis and the slave axis, where an amount obtained by superposing a motion amount δzIm for the master axis ZIm on a motion amount δzIIs for the slave axis ZIIs is supplied to the servo processing for the slave axis ZIIs. When a slave axis motion stop command is issued, the motion of the slave axis is stopped and a motion amount δzIm for the master axis ZIm is subtracted from the workpiece coordinate value of the slave axis ZIIs. This makes it possible to retain the positional relationship between the master axis and the slave axis, and hence easily resume the superposing control when the motion of the slave axis is restarted.

摘要： A numerical controller capable of mitigating mechanical shock caused by tool compensation while a machine tool is operated according to table data. X- and Z-axis path tables Tx, Tz store X- and Z-axis positions corresponding to reference positions (time or spindle position). A tool compensation table Tt stores X- and Z-axis compensation amounts (tool compensation numbers) associated with the respective reference positions. At every predetermined period, X- and Z-axis path table interpolators read command positions from the path tables Tx, Tz based on the reference position, and obtain command motion amounts by interpolation. X- and Z-axis tool interpolators read compensation amounts from the tool compensation table Tt based on the reference position, and obtain compensation motion amounts by interpolation. Adders add up the command motion amounts and the respective compensation motion amounts to drive respective motors. The tool compensation amounts are gradually varied, whereby mechanical shock does not occur.

摘要： A path table operation is performed while updating the reference positions. When a read-out command in the path cycle table is read out, the reference positions are withdrawn and reset, and the respective axial positions at the time of the initiation of the path cycle command are stored. From the next period, the target positions are determined by adding the positions at the time of initiation to the respective axial positions corresponding to the reference positions stored in the path cycle table, and a path table operation is performed. A single path cycle table is sufficient for storing commands for portions to be repeatedly worked.
