High-speed machining mode

Q: What does Mazak G-code G05 do?

G05 — High-speed machining mode on the MAZATROL SmoothX control (INTEGREX e-670H). The high-speed machining mode feature allows high-speed execution of programs used for the machining of free-curved surfaces that have been approximated using very small lines. In high-speed machining mode, microsegment machining capabilities improve by several times, compared with conventional capabilities. This allows the same machining program to be executed at several times the original feed rate, and thus the machining time to be reduced Conversely, a machining program that has been approximated using lines of several fractions of the original segment length, can also be executed at the same feed rate, so more accurate Combined use of the high-speed machining mode and the geometry compensation function allows more accurate machining to be implemented. If, moreover, a protruding section exists in the m

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 high-speed machining mode feature allows high-speed execution of programs used for the machining of free-curved surfaces that have been approximated using very small lines. In high-speed machining mode, microsegment machining capabilities improve by several times, compared with conventional capabilities. This allows the same machining program to be executed at several times the original feed rate, and thus the machining time to be reduced Conversely, a machining program that has been approximated using lines of several fractions of the original segment length, can also be executed at the same feed rate, so more accurate Combined use of the high-speed machining mode and the geometry compensation function allows more accurate machining to be implemented. If, moreover, a protruding section exists in the microsegment machining program, smooth interpolation can be conducted automatically by removing this illegal path. […]

G05 is one-shot (group 00) — it is valid only in the block where it is entered.

Address words

Note 1: Both commands must be given in a single-command block.
Note 2: Do not use both commands in the MDI operation mode; otherwise an alarm (807
ILLEGAL FORMAT) occurs.
2. Commands available in the high-speed machining mode
Only axis motion commands with the corresponding preparatory functions (G-codes) and feed
functions (F-codes), designation of sequence number, codes for Control Out and Control In
(parentheses), as well as M/S/T functions are available in the high-speed machining mode.
Setting data of any other type will result in an alarm (807 ILLEGAL FORMAT).
1. G-codes
The available preparatory functions are G00, G01, G02, G03, G17, G18, G19, G93 and G94.
The circular interpolation (helical interpolation unavailable) can be programmed with R
(radius designation) as well as with I and J (center designation). If the machining program
includes circular commands, however, set bit 2 of the F96 parameter to one (1).
F96 bit 2: Type of control for circular commands in the high-speed machining mode:
