basic Thread Sizing
On both
Machinist Calc
and
Machinist Calc Pro
, the
t
key
allows you to enter a numeric, fractional or metric Thread
Size and then toggle through the various available Thread
characteristics, as shown in the tables provided later in this
section.
When using the
t
key, the first entry is considered the
Thread Size. Upon entering the Thread Size, the Threads per
Inch (TPI) or Pitch is required. If the entered Thread Size is a
standard size, continuous presses of the
t
key will toggle
through the available common TPI or Pitches. Once the
desired TPI/Pitch is reached, pressing
O
stores the Thread
Size. If the Thread Size you enter is not a standard size or if
you have a non-common TPI/Pitch, you will need to directly
enter the TPI/Pitch value, pressing
t
after entering it in order
to store the Thread Size. Both of these entry methods are
covered in the examples provided within this section.
The following specifies the entry ranges that the calculator
allows for the Thread Size and TPI/Pitch values for numeric,
fractional and metric Thread Sizes:
Thread Size
TPI/Pitch
Numeric
0, 1, 2, 3, 4, 5, 6,
8, 10, 12, 14
less than 100
Fractional
0.06” to 6”
less than 100
Metric
1 mm to 300 mm less than or equal to 10
Note:
Entries outside of the ranges mentioned above will result in an
Entry Error.
