DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
a. Field of the Invention
This invention relates to a similar shape part program creation method and, more particularly, to a part program creation method suited to creation of a part program for machining a part having a plurality of similar shapes.
b. Description of the Related Art
In an automatic programming system for creating NC data using an automatic programming language such as APT (automatically programmed tools) or FAPT,
(a) a part program based on the automatic programming language is created by defining points, straight lines and circular arcs using simple symbols (this is referred to as "figure definition"), and defining a profile using the defined points, straight lines and circular arcs (referred to as "part profile definition"). Then, defining a tool path by an approach motion statement which causes the tool to approach, a profile motion statement which moves the tool along the part profile, and a withdrawal motion statement which causes the tool to withdraw (referred to as "motion statement definition"), and
(b) the part program based on the automatic programming language is subsequently converted into NC data comprising NC data (EIA codes or ISO codes) in a format capable of being executed by an NC unit.
When a part program is created for machining a part having a plurality of similar shapes (inclusive of identical shapes), the conventional part program creation method is such that motion statement definition for such operations as approach/profile motion/withdrawal must be repeated even though the machining method is the same. The problem that results is that a great amount of time is required to create the part program.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide a part program creation method through which a part program for machining a part having a plurality of similar shapes can be created quickly and easily.
Another object of the present invention is to provide a similar shape part program creation method in which a plurality of similar shapes to be machined are disposed on a screen and a part program is created while the state of arrangement among the shapes is verified and studied.
The present invention provides a similar shape part program creation method which creates a part program for machining a first shape and one or more shapes similar to the first shape. The part program creation method includes defining a profile of a part having a plurality of similar shapes, creating a part program for machining a first shape serving as a reference, designating a similar shaped to be machined under machining conditions identical with those of the first shape, and thereafter creating a part program, for machining the similar shape using the part program of the first shape.
