NC DATA PREPARATION METHOD FOR BORING.

摘要

An arbitrary hole shape pattern (HPT) and its machining procedures are specified interactively to register the result as hole kind data in a hole kind file (FLD). When the registered hole kind is designated from a keyboard (14) at the time of preparation of NC data for boring, an automatic programming portion (11) displays an interactive picture in accordance with the hole kind on CRT (13) so as to specify the hole shape dimension and tools used for each machining step and the NC data for machining the kind of the hole is prepared on the basis of these data.
