Abstract
A next command reference value close to a “the value L serving as a reference” is read from its own path table, and if there is the read command reference value in its own path table, then it is determined whether or not the “the value L serving as a reference” reaches the command reference value. When the “the value L serving as a reference” reaches the command reference value, if there is a waiting command of waiting for other path table, counting of the “the value L serving as a reference” is stopped. When waiting for the other path table is completed, the stop of counting of the “the value L serving as a reference” is released, the command is executed, and processing is continued.
Claims7
A numerical controller having a function of operation based on table format data, comprising:
- a memory which stores table format data, in which time or a position of a spindle or feed shaft serving as a reference is arranged so as to correspond to a position of a spindle or feed shaft other than the spindle or feed shaft of which position serves as a reference or an output of an auxiliary function, for each of the spindle or feed shaft other than the spindle or feed shaft of which position serves as a reference or the auxiliary function;
- and
- a reference value counter which inputs the time or the position of the spindle or feed shaft serving as a reference,
- wherein, sequentially reading the position of the spindle or feed shaft other than the spindle or feed shaft of which position serves as a reference or the output of the auxiliary function in synchronization with the value of the reference value counter, the position of the spindle or feed shaft other than the spindle or feed shaft of which position serves as a reference or the output of the auxiliary function is controlled,
- the reference value counter is provided for each spindle or feed shaft other than the spindle or feed shaft of which position serves as a reference or for each auxiliary function, and
- each of the table format data is executed based on each value of the reference value counter.
