NUMERICAL CONTROL DEVICE FOR CONTROL OVER MACHINE TOOL BASED ON SKIVING PROCESSING COMMAND

摘要

PROBLEM TO BE SOLVED: To provide a numerical control device capable of reducing an operator's load of creating a processing program for skiving processing.SOLUTION: A numerical control device 100 of the present invention comprises: command-program analysis means discriminating whether a block which has been read from a processing program is a skiving processing command; and skiving-processing-command-data computing means which, when the command-program analysis means has discriminated that the block is the skiving processing command, computes a route and a feed rate of a tool on the basis of a cut point route and a cut point feed rate instructed by the skiving processing command, the numerical control device 100 controlling a machine tool on the basis of the route and the feed rate of the tool that have been computed by the skiving-processing-command-data computing means.SELECTED DRAWING: Figure 3
