Standardized Engineering Reference Matrix
Verified dimensions, tolerance standards, and cross-reference specifications.
| M-Code | Function Name | Execution Timing | Typical Fanuc / Haas Behavior | Shop-Floor Safety & Usage Note | Action |
|---|---|---|---|---|---|
| M00 | Mandatory Program Stop | Immediate at block | Halts axis feed, spindle, and coolant unconditionally until Cycle Start pressed | Used for manual part flip, chip clearing, or in-process micrometer check | |
| M01 | Optional Program Stop | Conditional on panel key | Pauses machine only if "OPT STOP" button is illuminated on operator console | Place after every tool operation for first-article prove-out inspection | |
| M03 | Spindle On Clockwise (CW) | With S-word RPM | Starts spindle rotation in standard right-hand cutting direction (e.g. S6000 M03) | Verify tool hand before execution; always pair with explicit S speed | |
| M04 | Spindle On Counter-Clockwise | With S-word RPM | Starts spindle in reverse left-hand rotation (or rigid tapping retract) | Used for left-hand drills/taps or back-boring operations | |
| M05 | Spindle Stop | Before Z retract / ATC | Decelerates and stops main spindle motor completely | Automatically invoked by M06 or M30 on modern controls | |
| M06 | Automatic Tool Change (ATC) | With T-word | Indexes carousel/arm and swaps tool in spindle (e.g. T04 M06) | Ensure safe Z-axis clearance (G28 G91 Z0) prior to M06 on non-macro machines | |
| M08 / M09 | Flood Coolant On / Off | Modal Auxiliary | M08 activates main flood coolant pump; M09 shuts off all coolant valves | Use M88/M89 for high-pressure Through-Spindle Coolant (TSC) | |
| M30 | Program End & Rewind | End of main program | Stops spindle/coolant, resets modal states, and rewinds cursor to top of file | Standard final block of every standalone CNC G-code file |
