Longitudinal cut-off cycle
Machine-specific. This G-code reference is specific to the Mazak INTEGREX e-670H / e-670H-S with the MAZATROL SmoothX control (EIA/ISO programming manual H747PB0030E). G-code availability depends on fitted options, and groups and behaviour differ between Mazak models and control generations — verify against the manual for your own machine before programming with any code.
What it does
This function is used for smooth disposal of machining chips in longitudinal cut-off machining. For SS materials which produce hard-to-cut machining chips this function can be managed for easy machining chip disposal. This function is used for smooth disposal of machining chips in transverse cut-off machining. This allows easy disposal of machining chips in face turning as well.
G274 is modal (group 09) — it stays in effect until another code of the same group replaces it.

Address words
- e : Return distance
- The value is modal and remains valid until it is overwritten with a new value.
- x : Final X-axis position in absolute/incremental data
- z : Final Z-axis position in absolute/incremental data
- i : X-axis movement step (in an absolute value)
- k : Z-axis depth of cut (in an absolute value)
- d : Tool escape distance at the bottom of cut
- Normally set in an absolute value. When omitting the arguments X and P, however, set
- the value with a sign as required for the direction of escape.
- f : Feed function (rate of feed)
- s : Spindle function
- The distance “e” is set by parameter TC74 (pecking return distance in grooving process).
- A d
- i
