BRIEF SUMMARY
DESCRIPTION
1. Technical Field
This invention relates to a method of revising a profile, and more particularly, to a profile revising method for specifying a profile by figure definition statements in an automatic programming language and revising a corner portion such as a chamfered or rounded corner portion of the designated profile.
2. Background Art
In an automatic programming system for creating NC data using an automatic programming language such as APT (automatic programming 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 "), defining a profile using the defined points, straight lines and circular arcs, and then defining a tool path along the profile (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.
In order to define a predetermined profile upon inserting roundness at a corner portion after figure definition of various figure elements S.sub.1 -S.sub.3, C.sub.1 shown in FIG. 7, the defined figure element symbols are used to enter the following: radius r.sub.1 sides S.sub.1, S.sub.3 and roundness of radius r.sub.2 between sides S.sub.1, S.sub.2 by the aforementioned motion statement, as shown in FIG. 8.
More specifically, the figure elements are arranged in order along the profile and rR (where r is a radius value and R is a letter of the alphabet) indicating rounding is disposed between the linear symbols which indicate the two straight lines at which roundness is to be inserted. Thus, when a profile having roundness is defined, it is required that the operator know which sides are contacted by the circular arc of the roundness to be inserted. The same is true also when it is attempted to revise roundness after a profile has been defined. When a profile is displayed on a display screen and a problem is found with regard to a prescribed rounded corner portion, the operator must check the symbols (let these be S.sub.i, S.sub.j) of the sides adjacent this corner portion and revise the profile by entering
Furthermore, even if corner arcs appear to be the same, the circular arc of a corner portion E.sub.1 (FIG. 8) is defined by roundness r.sub.1 R, and the circular arc of a corner portion E.sub.3 is defined as a part of circle C.sub.1. In other words, if roundness is to be revised, the revision must be made while being aware of whether the circular arc was defined by the qualifier "R" indicating rounding or by the definition identification "C" indicating a circle. This also is a troublesome operation. Though the foregoing relates to a rounded corner portion, the same is true for a chamfered corner portion.
Accordingly, an object of the present invention is to provide a profile revising method through which a revising operation can be performed by desigating a corner portion such as a chamfered or rounded corner portion desired to be revised and clarifying the location at which the revision is to be made.
DISCLOSURE OF THE INVENTION
In the profile revising method of the present invention, revision of chamfering or rounding is designated, whereby chamfered corner portions in the case of chamfering revision and rounded corner portions in the case of rounding revision are displayed in a color different from that of the other portions of the profile. By designating a corner portion displayed in the different color, the chamfered corner portion or rounded corner portion to be revised is specified to revise the dimensions of this corner portion or delete the corner portion.
