Common notices for machining operations
To ensure the safety and correctness of machining, you must observe the following notices during machining operations:
● Reference point approach is required only for machine tools equipped with incremental encoders.
● Before running the spindle manually, make sure you have activated the tool.
● Before executing M functions, make sure all the axes are in safe positions.
● During handwheel assignment, make sure there is no obstacle when moving the tool to avoid tool collision.
● To guarantee the safety and correctness of machining, you must verify the tool setup result.
● You must distinguish the direction of tool wear compensation clearly before entering the tool wear offsets.
● Before machining the workpiece on the machine, make sure the following preconditions are met:
– The PRT mode and the dry run feedrate are deactivated.
– The feedrate override is 0%.
– The safety door is closed.
● After changing important data, it is recommended to carry out an internal data backup immediately.
Switching on and referencing
point approach is required only for machine tools equipped with incremental encoders.
Turn on the power supply for the machine tool.
Release all emergency stop buttons on the machi
ne. By default, the control system is in
reference point approach (REF.POINT) mode after startup.
If a machine axis is equipped with an absolute encoder, the axis is referenced
automatically after the control system starts and therefore reference point approach is
unnecessary. The circle symbol (lower-
left figure) next to the axis identifier indicates that
the axis is already referenced.
If a machine axis is equipped with an incremental encoder, the axis is not referenced
after the control system starts. The circle symbol (lower-right figure) next to the axis
identifier indicates that the axis has not been referenced. Proceed to Step 3.
