SIMULTANEOUS FOUR-AXIS LATHE MECHINING TIME BAX-GRAPH DISPLAY METHOD

摘要

A device consists of a processor (11), a ROM (12), a RAM(13), a working memory (14), a keyboard (15), an NC data output device (17) and a character display (16) comprising a display control unit (16a), a character generator (16b), an image buffer (16c), a timing signal generator (16e), a CRT (16a), a need control unit (16f), a brightness control unit (16g) and a deflector circuit (16h). When an IC program for a simultaneous four-axis lathe is prepared, a machining time (T1i,T2i) for each of the synchronous steps for each tool and a tool machining time (Tm) are determined. The machine times are then displayed in the form of a bar graph.
