摘要： A synchronizing control apparatus for synchronously rotating master and slave main spindles of a pin grinder, wherein a servomotor for the slave main spindle is rotated at a speed corresponding to a compensated command value while the master main spindle is rotated at a speed corresponding to a noncompensated command value. The compensated command value is calculated based on a synchronizing error between the master and slave main spindles at a predetermined interval longer than the length of instable condition of a servo loop for the slave main spindle. When the synchronizing error is larger than a predetermined limit value, the command value for the slave main spindle is gradually compensated in order to prevent the compensated command value from changing too abruptly.

摘要： It is one object of the present invention to provide a program writing method of numerical controller, a numerical controller and a cutting machine controlled thereby, achieving the writing of a plurality of programs relating to one axis to perform a high efficiency in a lot of productions. A next or later user-set-program controlling a duplicated axis controlled by plural user set programs identifies a virtual axis virtually controlled by one user set program. A program is written to replace the duplicated axis with the virtual axis. A control amount calculated by the user set program identifying the virtual axis is added to a control amount inputted to a correspondent axis driving program as a control amount of the duplicated axis before replacing the virtual axis.
