Okuma’s OSP CNC monitor series serves as the primary human–machine interface for the OSP control, combining the display, function keys, and operator input devices used to navigate modes, menus, and machining data.
In the OSP 5000/5020 generation, the NC operation panel is common across machines and uses a CRT-based display (12-inch on the 5000/5020 series, 9-inch on the earlier 500 series) with eight function keys located below the screen to access mode-dependent menus. The OSP 5000 series lineage dates back to 1981, added integrated graphics in the mid-1980s, and the OSP 5020 generation increased control speed and accuracy using high-precision digital servo technology and a 32-bit, dual-engine architecture that enabled much higher cutting feedrates than earlier versions. These monitor/panel assemblies interface with the control electronics to carry video to the display while also exchanging operator inputs (keyboard and switch data) and panel status information required for machine operation and diagnostics. In newer OSP operator panel implementations, two touchscreen monitor sizes are offered—15-inch and 21.5-inch—both with tilt mechanisms, with the larger panel emphasizing enhanced visibility for concurrent operational and application data and the smaller panel prioritizing space-saving installation without dropping core functions.
