Abstract
Abstract A method and apparatus for creating numerical control data by entering coordinates which specify points on a drawing DR placed on a tablet 13a. The method includes entering coordinate values of points on the drawing DR by designating the points, and entering information for specifying the category of numerical control data to be specified. Numerical control data is created using the classification information and the coordinates of the points. The data can be created simply in a short period of time without requiring special skills.

Claim 2
Independent Claim
61 words
A method of creating numerical control data by entering points from a drawing placed on a tablet, comprising the steps of: (a)entering coordinate values of the points by designating said points on the drawing; ( b )entering information specifying the classification of numerical control data to be created; and (C)creating numerical control''data using said information and the coordinates of said points.
Claim 3
Dependent Claim
21 words
The method according to claim 1, in which said information is indicative of rapid traverse, linear cutting or circular arc cutting.
Claim 4
Dependent Claim
41 words
The method according to claim 1 or claim 2, in which the entry of said information is made possible after a predetermined area of a switch function zone, provided at any location on said tablet, is designated by ceerdinate designating means.
Claim 5
Independent Claim
63 words
An apparatus for ereating numerieal control data by entering points from a drawing placed on a tablet, comprising: for means/(a) entering coordinate values of the points by designating said points on the drawing; for means/(b) entering information specifying the classification of numerical control data to be created; and for means/(c) creating numerical control data using said information and the coordinates of said points.
Claim 6
Independent Claim
63 words
An apparatus for ereating numerieal control data by entering points from a drawing placed on a tablet, comprising: for means/(a) entering coordinate values of the points by designating said points on the drawing; for means/(b) entering information specifying the classification of numerical control data to be created; and for means/(c) creating numerical control data using said information and the coordinates of said points.
Claim 7
Dependent Claim
144 words
The apparatus according to claim 4, comprising: of an OR gate for taking the OR/switch signals produced by each of a plurality of switches provided on coordinate designating means; a counter for counting output pulses produced by said OR gate, the status of said counter changing with each counted output pulse; a multiplexer for applying coordinate values produced by the tablet, to a predetermined one of a plurality of registers in accordance with the value of the count in said counter; said plurality of registers for storing coordinate values successively in accordance with the count in said counter; a processor which receives the coordinate values stored in said plurality of registers as well as information specifying the category of numerical control data, for creating numerical control data using said information and said coordinate values; and a data memory for storing created numerical control data.
Claim 8
Dependent Claim
50 words
4 or 6 . The apparatus according to claim/5, in which the coordinate designating means produces coordinate values of points by designating points on a drawing placed on said tablet, and has said plurality of switches for producing information specifying the category of the numerical control data to be created.
