PROGRAMMING SYSTEM FOR INTERACTIVE NUMERICAL CONTROL DEVICE

摘要

A system for producing NC programs for interactive numerical control devices. The operator defines forms of raw materials and parts (S1, S2) and specifies whether the secondary operations are included in a production process (S3) or not. The definitions of cut regions of primary working are performed in just the same manner as with an ordinal double spindle lathe and the forms of the raw materials and the parts are drawn reversely in the secondary working (S6) to define the cut regions of the secondary working in images similar to the ones of the primary working (S7). On the basis of such definitions of the necessary working conditions, the interactive numerical control device outputs NC data for the secondary working and for the primary working (S8) separately.
