Okuma M-codes (turning) – reference table
Complete reference table of Okuma M-codes for lathes: more than 1,100 codes from M00 to M1255 with descriptions and standard/option designation.
Okuma’s OSP control uses M-codes (miscellaneous functions) to switch machine functions such as the spindle, coolant, chuck, tailstock, and tool change. This reference lists the M-codes for Okuma lathes from M00 to M1255.
Machine-dependent assignment
The “Standard/Option” column shows whether a code is part of the base configuration or requires an optional machine function. Which codes are actually available depends on the model and equipment – when in doubt, your machine’s documentation applies.
Essential M-codes
These codes are assigned identically on practically every Okuma lathe and cover day-to-day programming:
