Glossary
accepted data
data that fall within the acceptable limits in a fastening
strategy
accepted rundown
a run cycle within limits
angle capability indexes
a measure of acceptable variation of final angle values in
a fastening process
angle control
a fastening strategy by which you are controlling a tool by
predetermined angle limits
angle encoder
a device that measures the angle of rotation
angle high
active if final angle > angle high limit
angle high limit (AHL)
the maximum acceptable angle for a run cycle
angle limits
the range between the maximum and minimum accept-
able angle for one cycle
angle low
active if final angle < angle low limit
angle low limit (ALL)
the minimum acceptable angle for a run cycle
angle monitor
a fastening strategy by which you are monitoring a tool by
predetermined angle limits
angle reject
a cycle rejected when the acceptable angle is not
achieved
application
a programmed setting of the unit for a given application;
TME 100 has eight application settings. Often referred to
as product group
application select 0-2
application selects 0-2 are used to select applications 1-8
using a binary count of 0-7 where app. sel. 0 is the least
significant bit
baud rate
the frequency at which the unit communicates
capability of process (Cp)
The ratio of the process tolerance to 6 standard devia-
tions. Ranges from 0.0 to infinity with larger values indi-
cating a more capable process. (Often referred to as
Process Potential Index or Inherent Capability Index.)
capability index (Cpk)
An index combining the process potential and the mea-
sure of the difference between process and the specifica-
tion mean. CPK will equal Cp if the process mean is
centered on the target (nominal) specification value; if
CPK is negative, the process mean (X-Bar) is outside the
specification limits; if CPK is between 0 and 1, then some
of the 6 sigma spread will fall outside of the specifications;
if CPK is larger than 1 then the 6 sigma spread is com-
pletely within the specification tolerance.
control parameters
the parameters that define the fastening strategy
sequence for a given tool
cycle complete
active whenever tool is not running
cycle NOK
active if torque/angle/yield are outside limits or some
other error has occurred
cycle OK
active if torque/angle/yield are within programmed limits
