3.4.2 Cleaning air base MACS (4-beam type)
The function called “base MACS” is used to periodically check the coordinates of marks at each point in the
machine with a fiducial camera, in order to offset thermal expansion in the machine base.
The “air base MACS” for the YSM40R 4-beam type machine utilizes marks used with an optical system tool.
The lens of this optical system tool requires periodic inspection and cleaning.
