Selection of machine coordinate system

Q: What does Mazak G-code G53 do?

G53 — Selection of machine coordinate system on the MAZATROL SmoothX control (INTEGREX e-670H). The above command permits moving the tool to the commanded position in the machine coordinate system at the rate of rapid traverse. G53 is valid only for the commanded block. To move a tool to the position specifically set for the machine including tool change position, command G53 using the machine coordinate system. A base point on the machine is referred to as the machine zero point. Machine zero point depends on machine specifications. A coordinate system using machine zero point as the zero point of coordinate system is referred to as machine coordinate system. The tool cannot always move to the machine zero point. In some cases, machine zero point is set at a position to which the tool cannot move. Machine coordinate system is established when the reference point return is executed after

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 above command permits moving the tool to the commanded position in the machine coordinate system at the rate of rapid traverse. G53 is valid only for the commanded block. To move a tool to the position specifically set for the machine including tool change position, command G53 using the machine coordinate system. A base point on the machine is referred to as the machine zero point. Machine zero point depends on machine specifications. A coordinate system using machine zero point as the zero point of coordinate system is referred to as machine coordinate system. The tool cannot always move to the machine zero point. In some cases, machine zero point is set at a position to which the tool cannot move. Machine coordinate system is established when the reference point return is executed after the power is turned on. Once the machine coordinate system is established, it is not changed by reset, workpiece coordinate system setting (G92), local coordinate system setting (G52) and other operation unless the power is turned off.

G53 is one-shot (group 00) — it is valid only in the block where it is entered.
