Abstract

Abstract A method of preparing an NC part program includes a figure-defining sentence defining a figure (MFIG), a motion-defining sentence defining the motion of a tool (TL), and auxiliary machining data, such as feed rate and rotational speed of spindle. The method comprises the steps of: prestoring motion-defining sentences corresponding to various figures together with figure names; supplying a figure name and defining the figure (MFIG) while specifying a point (P,), straight lines (S, to S,) or circular arcs; and combining the motion-defining sentence corresponding to the supplied figure name and the specified figure-defining sentence to prepare a part program.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 88 words
A part program creation method for creating an NC part program comprising a graphic definition statement defining a graphic, a motion definition statement defining a tool path, and auxiliary machining information such as feed velocity and spindle rotational velocity, characterized by having steps of storing, in a memory, motion statements conforming to respective ones of various shapes, defining a graphic by a graphic input device, and creating a part program by combining said defined graphic definition statement and a prescribed one of the motion statements registered in advance.
Claim 2
Dependent Claim 88 words
A part program creation method for creating an NC part program comprising a graphic definition statement defining a graphic, a motion definition statement defining a tool path, and auxiliary machining information such as feed velocity and spindle rotational velocity, characterized by having steps of storing, in a memory, motion statements conforming to respective ones of various shapes, defining a graphic by a graphic input device, and creating a part program by combining said defined graphic definition statement and a prescribed one of the motion statements registered in advance.
Claim 3
Dependent Claim 19 words
A part program creation method according to claim 1, characterized in that said motion statement includes auxiliary machining information.
Claim 4
Dependent Claim 29 words
A part program creation method according to claim 2, characterized by having a step of entering an identifier of the motion statement combined with the defined graphic definition statement.
Claim 5
Dependent Claim 34 words
A part program creation method according to claim 3, characterized in that said step of defining a graphic defines the graphic by specifying a predetermined point, straight line and circular arc on the graphic.
Claim 6
Dependent Claim 39 words
A part program creation method according to claim 4, characterized in that said straight line is entered by specifying two points on said straight line, and said circular arc is entered by specifying three points on said circular arc.
Claim 7
Dependent Claim 33 words
A part program creation method according to claim 5, characterized in that a point on the graphic is designated by said graphic input device, whereby the coordinate values of said point are entered.
Claim 8
Dependent Claim 81 words
A part program creation method according to claim 5, characterized by having steps of storing beforehand, in a memory, image information relating to a tool path pattern corresponding to said registered motion statement, displaying said tool path pattern on a display unit on the basis of image information designated by a program identifier when the program identifier is entered, and displaying on the display unit a predetermined element from among a point, straight line and circular arc to be entered next.
Claim 9
Dependent Claim 127 words
A part program creation method for creating an NC part program comprising a graphic definition statement defining a graphic, a motion statement defining a tool path, and auxiliary machining information such as feed velocity and spindle rotational velocity, characterized by having steps of creating a graphic definition statement by using symbols representing points, straight lines and circular arcs, with data specifying these points, straight lines and circular arcs, which constitute the graphic, being left unknown, registering an incomplete part program comprising said graphic definition statement and a motion statement, specifying each of said points, straight lines and circular arcs by a graphic input device, and creating a complete part program by using these specified point data, straight line data, circular arc data and said registered part program.
Claim 10
Dependent Claim 127 words
A part program creation method for creating an NC part program comprising a graphic definition statement defining a graphic, a motion statement defining a tool path, and auxiliary machining information such as feed velocity and spindle rotational velocity, characterized by having steps of creating a graphic definition statement by using symbols representing points, straight lines and circular arcs, with data specifying these points, straight lines and circular arcs, which constitute the graphic, being left unknown, registering an incomplete part program comprising said graphic definition statement and a motion statement, specifying each of said points, straight lines and circular arcs by a graphic input device, and creating a complete part program by using these specified point data, straight line data, circular arc data and said registered part program.
Claim 11
Dependent Claim 53 words
A part program creation method according to claim 8, characterized by having steps of registering in a memory, together with respective identifiers, a plurality of incomplete part programs conforming to respective ones of tool path patterns, and specifying a prescribed incomplete part program by entering the identifier of one of said part programs.
Claim 12
Dependent Claim 79 words
A part program creation method according to claim 9, characterized by having steps of registering beforehand, in a memory, image information relating to a tool path pattern corresponding to said incomplete part program, displaying said tool path pattern on a display unit on the basis of image information designated by a program identifier when the program identifier is entered, and displaying on the display unit a graphic element which is to be entered next by the graphic input device.
