Tapping mode

Q: What does Mazak G-code G63 do?

G63 — Tapping mode on the MAZATROL SmoothX control (INTEGREX e-670H). Command G63 enters the NC unit into a control mode suitable for tapping. This mode has the following features:  The cutting feed override is fixed at 100%.  Commands for deceleration at block-to-block connections are invalidated.  The feed hold function is invalidated.  The single-block function is invalidated.  Tapping-mode signal is output. The G63 command mode will remain valid until it is cancelled by geometry compensation mode (G61.1), exact-stop check mode (G61), automatic corner override mode (G62) or cutting mode Command G64 enters the NC unit into a control mode proper to obtain smoothly cut surfaces. Unlike the exact-stop check mode (G61 command mode), the cutting mode allows the next block to be executed without decelerating/stopping the machine between cutting feed blocks. The G64 command mode is clear

Q: What is the programming format of G63?

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

Command G63 enters the NC unit into a control mode suitable for tapping. This mode has the following features:  The cutting feed override is fixed at 100%.  Commands for deceleration at block-to-block connections are invalidated.  The feed hold function is invalidated.  The single-block function is invalidated.  Tapping-mode signal is output. The G63 command mode will remain valid until it is cancelled by geometry compensation mode (G61.1), exact-stop check mode (G61), automatic corner override mode (G62) or cutting mode Command G64 enters the NC unit into a control mode proper to obtain smoothly cut surfaces. Unlike the exact-stop check mode (G61 command mode), the cutting mode allows the next block to be executed without decelerating/stopping the machine between cutting feed blocks. The G64 command mode is cleared by geometry compensation mode (G61.1), exact-stop check mode (G61), automatic corner override mode (G62) or tapping mode (G63). In the initial state of the NC unit, the cutting mode is selected.

G63 is modal (group 13) — it stays in effect until another code of the same group replaces it.
