Engraving function

Q: What does Mazak G-code G140 do?

G140 — Engraving function on the MAZATROL SmoothX control (INTEGREX e-670H). This function enables an arbitrary character string to be inscribed by chip removal on the machined surface. The combined use of another preparatory function and special codes allows, respectively, in- scription to be performed on various types of machined surfaces and the current information (parts count, date and time, etc.) to be added to the inscription.

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

The combined use of another preparatory function and special codes allows, respectively, in- scription to be performed on various types of machined surfaces and the current information (parts count, date and time, etc.) to be added to the inscription.
