Abstract
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.
