ABSTRACT:
An automatic programming device has a display structure, an input structure for entering graphical data in accordance with information that is displayed by the display, and a threshold level variation device for varying a threshold level which forms a reference for rounding-off numerical calculation errors during graphical data processing. The programming device also has a reading structure for reading an NC program created in NC data, and a calculator which analyzes the NC program read via the reading structure, generates pattern information specified by each graphical element of points, line segments and circular arcs, and generates tool path information specifying the sequence of tool progress on the pattern.
