A plurality of figures are displayed on a screen (1), portions (4, 5) to be enlarged or contracted of the plurality of figures (2, 3) displayed on the screen (1) are designated, and the figures are drawn on enlarged or contracted scales of independent magnifications. This makes easy to check shapes of complex portions.

Description

明 細 図形拡大縮小制御方式 技 術 分 野  Description Figure scaling control method
本発明は数値制御装置等の加工プログラムに含まれる図形 を拡大あるいは縮小表示する図形拡大縮小制御方式に関し、 特に複数の図形を同時に拡大縮小するよう に した図形拡大縮 小制御方式に関する。 背 景 技 術  The present invention relates to a graphic enlargement / reduction control method for enlarging or reducing a graphic included in a machining program of a numerical controller or the like, and more particularly to a graphic enlargement / reduction control method for simultaneously enlarging or reducing a plurality of graphics. Background technology
自動プログラ ミ ング内蔵の数値制御装置の C R T画面には 加工プログラム等に含まれる加工部品の形状が表示される。 この場合、 部品形状が平面的な場合は一方向から見た図形の みでも形状を表示する こ とができ る力；、 立体部品形状を表す 場合には複数の方向からみた図形が必要になる。  The CRT screen of the numerical controller with built-in automatic programming displays the shape of the machined part included in the machining program and the like. In this case, if the part shape is planar, the force that can display the shape only with a figure viewed from one direction; if the shape represents a three-dimensional part, a figure viewed from multiple directions is required .
従って、 C R T画面には加工部品の複数の平面における投 影図を、 画面の範囲を分割して同時に描画している。 そ して 複雑な形状の図形はその画面を拡大する こ とによって铂部の チヱ ッ クを行ない、 あるいは縮小する こ とによって部品の全 体の形状を把握するようにしている。  Therefore, on the CRT screen, the projections of the machined part on a plurality of planes are simultaneously drawn while dividing the range of the screen. For a figure with a complicated shape, some parts are checked by enlarging the screen, or the whole shape of the part is grasped by reducing it.
しかし、 従来の図形拡大縮小機能は画面全体の倍率を変更 する ものであった。 このため、 ある平面における投影図だけ を拡大してチュ ッ ク しょう と しても、 同じ画面上の他の平面 の投影図もオペレータの意図に反して同時に拡大されて しま うので、 加工プログラムのチェ ックに支障をきたしていた。 発 明 の 開 示 However, the conventional graphic scaling function changes the magnification of the entire screen. For this reason, even if you try to magnify only the projection on one plane, the projections on other planes on the same screen are simultaneously enlarged contrary to the operator's intention. Therefore, the checking of the machining program was hindered. Disclosure of the invention
