What is the command associated with a work shift offset?

The command associated with a work shift offset is G54. In CNC programming, G54 is one of the several work coordinate system commands that allows the operator to establish a specific work offset. This command enables the milling machine to recognize the geometry of the workpiece relative to its own coordinate system. By utilizing G54, you can define where the machine should interpret its zero point for that particular setup, which is essential for accurate machining operations.

This is particularly important when working with multiple setups or parts, as it allows for quick referencing and changes without having to reprogram the entire part geometry. Understanding work offsets is crucial for efficient setup and programming in CNC milling operations.

The other options refer to different functions in CNC programming:

• M8 is typically used to turn on coolant.

• M5 is used to stop the spindle.

• G83 denotes a canned cycle for peck drilling operations.

These commands help manage different aspects of CNC machining but do not pertain to defining work offsets like G54 does.
