There ar e two se pa r,lIe procedures for this step, depending on
whether your ma chine 's sp indl e (t oo lho lder ) is oriented ver-
tically or horizontall y.
2. I ns tallation of the St rai ghtness Reflector
Aft er the Optical Square and the Interferometer have been installed and a li gned you will use
the La se r beam to position the Reflector.
3. Final Adjustments
You will u se a speci al technique to a dju st the Reflector to bring the beams back to the l ase r

N OTE
A machine with a vertical s pindle should have sp ace behind the
spi ndle to mount either the Strai ghtn ess R eflecto r or the Optical
Sq uar e.
1. Attach fhe Opti ca l Square to i ts Mount ( See Figure 12 -4) and orient it on its side so its slots are
parallel
to the machine's tabl e.
2. Identif y the axes you are going to measure to make your Sq uarene ss measurcmenl. I dentify
which axis will be your first measurement ax is and whi ch will be yo ur second. Try to ma x imi ze
travel paths f or each ax i s. (The Optical S quar e is fairly large and will shorten theaxis it is used
to measure. )
3. P os ition the Optical Squa re at the ap ex of yo ur square with each of it s slots facing one
measurement ax is.
This should be
out in front or to the s id e of the mac hin e si n ce yo ur seco nd measurement will
be made without the Optical Sq uare and will require a straig ht line from the laser Head,
through the
Interferomet er, an d into the R eflecto r.
4. Attach the Straightne
ss I nterferometer to it s mounting hardware (see Figure 10 -3), and to the
ma chine 's s pindle , by -
• attaching the Height Adjuster to a Post as yo u would for table mo untin g, or
• sc rewing its base d ire ctly into the post, or -
• screwing the Post into the Height Adju ster after r emov ing the large knurl ed knob.
This
