NUMERICAL-CONTROL MACHINING-PROGRAM CREATION DEVICE

摘要

To provide a numerical-control machining-program creation device that creates a numerical-control machining program including turning machining based on shape data of a workpiece. The numerical-control machining-program creation device generates a turning-machining removal shape indicating a shape to be removed by turning machining based on a turning sectional shape, extracts a turning groove shape from the turning-machining removal shape, and creates the numerical-control machining program for turning machining based on a shape obtained by separating the turning groove shape from the turning-machining removal shape.

主权项

1. A numerical-control machining-program creation device that creates a numerical-control machining program including turning machining based on shape data of a workpiece, comprising:
a turning sectional-shape generation unit that generates a three-dimensional turning shape designating a turning shaft as a rotation central axis from shape data of a workpiece, and generates a two-dimensional turning sectional shape based on the generated turning shape; a turning-machining removal-shape generation unit that generates a first turning-machining removal shape indicating a shape to be removed by turning machining based on the turning sectional shape; a turning-groove-shape extraction unit that extracts a convex shape, having a groove width equal to or less than a set groove width and a groove depth equal to or less than a set groove depth, as a turning groove shape from the first turning-machining removal shape; and a numerical-control machining-program creation unit that creates a numerical-control machining program for turning machining based on a second turning-machining removal shape obtained by separating the turning groove shape from the first turning-machining removal shape.
