Field of the Invention The present invention relates to a machined shape input device and method using a machining program in a computer numerical control machine tool, and more particularly, to a device and method for providing a more easily and conveniently input of a shape to be machined.

Numerical control (NC) of machine tools for cutting is now rapidly progressing. In recent years, machine tools equipped with computer numerical control (CNC), which has further advanced numerical control (NC) by automatically controlling machine tools using a computer equipped with a numerical control program, are rapidly spreading. to be.

A computer numerical control machine tool is operated by a numerical control program, so a skilled NC programmer is required, and the NC programmer must program a part program.
