The purpose of tool alignment is to determine the spatial position relationship between workpiece coordinate system and machine coordinate system through tool alignment or tool alignment, and input tool alignment data into the corresponding storage location. It is the most important operation content in nc machining, and its accuracy will directly affect the machining accuracy of parts. Knife alignment operation is divided into X, Y and Z knife alignment.

1. Start the machine back to the mechanical origin;

2. Manually move the knife tip to the original position you want to move;

3. After the position is determined, adjust the coordinates of the workpiece in three directions of XYZ to 0

Then the first tool, this is the tool instrument precision carving machine operation method, if there is no tool instrument, each time to manually tool.
