Rim and Face Method
See Face-rim Method.
Rise/Run
For smaller angles, the ratio obtained when the change in offset between two cen-
terlines is divided by the distance along either centerline (between the points of
offset measurement). In effect, it is the slope of one line in a plane compared to
another line in the same plane. Angularity is normally specified in mils/inch, or
milliradians which is rise/run.
Rotor
The part (or assembly of parts) of a machine that spins or revolves as a single unit.
For alignment purposes, the shafts of both machines are the rotors.
RS232
A serial, asynchronous communication standard; a type designation for cables that
are used to connect communications ports on host computer, analyzer, and tele-
phone modems.
Sag
Deflection due to gravity acting on a cantilevered or otherwise supported object.
Mechanical brackets always sag a certain amount. This sag must be corrected for if
machine moves are to be calculated correctly.
Secondary Alignment
The act of measuring off-line to on-line machine movement.
Shim
A thin piece of metal material inserted between the base and machine feet to pro-
duce precise vertical adjustments of the machine centerline.
Slave
When used as a communications term, it is the unit that is controlled when data is
transferred.
Soft Foot
A term used to describe any condition where tightening or loosening the bolt(s) of
a single foot distorts the machine frame. Also the name of a method used to mea-
sure this condition.
