Abstract
A graphics, such as a shop drawing of a workpiece worked by a machine tool, is inputted as working data in an automatic programming function in accordance with the natural graphic recognition order for an operator, and the system therefor includes the steps of first designating the shape of a basic graphics of the workpiece, and then designating sizes of the basic graphics, and finally designating the shape and sizes of auxiliary graphics of the workpiece.
Claims3
A system for inputting a shape including working data of a workpiece for a machine tool in an automatic programming function comprising the steps of:
- demanding input of basic graphics by an operator by displaying reference lines or grids on a graphic display unit through a graphic display control unit;
- generating basic graphic elements by operating a joy-stick and inputting a series of basic graphic element groups by the operator in a manner corresponding to one stroke of a brush due to the generation of said basic graphic elements;
- displaying basic graphics on said graphic display unit through said graphic display control unit by recognizing said basic graphic elements through a basic graphic element recognition control unit;
- displaying size lines on said graphic display unit and demanding input of size values by the operator by recognizing necessary portions of said size values to determine said basic graphics through said basic graphic element recognition control unit and by transmitting said necessary portions to said graphic display control unit;
- obtaining correspondences between said basic graphic elements and inputted size values and determining said basic graphics through said basic graphic element recognition control unit by inputting size values corresponding to said size lines;
- reading out shapes and size of basic graphic element arrays of said determined basic graphics through said basic graphic element recognition control unit;
- displaying precise basic graphics on said graphic display unit by transmitting said shapes and sizes of the basic graphic element arrays to said graphic display control unit;
- demanding auxiliary input of corner portions by the operator by recognizing said corner portions of said basic graphics through an auxiliary graphic element recognition control unit;
- inputting types and sizes of auxiliary graphics or information which indicates the absence of said auxiliary graphics;
- and
- repeating said reading out, displaying, transmitting, demanding and inputting processes for respective corner portions, whereby the types and the sizes of said auxiliary graphics are inserted into pertinent portions of said basic graphic element arrays which are formed with shapes and sizes and input of graphics.
