 The last entry (a comment) is optional.
 It makes reading easier if the entries are arranged in columns, as shown
 in the table, but the only format requirement is that there be at least
 one space or tab after each of the first three entries on a line and a
 space, tab, or newline at the end of the fourth entry.
 The meanings of the columns and the type of data to be put in each are
 as follows.
\layout Standard

The 
\begin_inset Quotes eld
\end_inset 

Pocket
\begin_inset Quotes erd
\end_inset 

 column contains the number (unsigned integer) which represents the pocket
 number (slot number) of the tool carousel slot in which the tool is placed.
 The entries in this column must all be different.
\layout Standard

The 
\begin_inset Quotes eld
\end_inset 

FMS
\begin_inset Quotes erd
\end_inset 

 column contains the number (unsigned integer) which represents a code number
 for the tool.
 The user may use any code for any tool, as long as the codes are unsigned
 integers.
 This is typically the same as the pocket number.
\layout Standard

The 
\begin_inset Quotes eld
\end_inset 

TLO
\begin_inset Quotes erd
\end_inset 

 column contains a real number which represents the tool length offset.
 This number will be used if tool length offsets are being used and this
 pocket is selected.
 This is normally a positive real number, but it may be zero or any other
 number if it is never to be used.
\layout Standard

The 
\begin_inset Quotes eld
\end_inset 

Diameter
\begin_inset Quotes erd
\end_inset 

 column contains a real number.
 This number is used only if tool radius compensation is turned on using
 this pocket.
 If the programmed path during compensation is the edge of the material
 being cut, this should be a positive real number representing the measured
 diameter of the tool.
 If the programmed path during compensation is the path of a tool whose
 diameter is nominal, this should be a small number (positive, negative,
 or zero) representing the difference between the measured diameter of the
 tool and the nominal diameter.
 If cutter radius compensation is not used with a tool, it does not matter
 what number is in this column.
\layout Standard

The 
\begin_inset Quotes eld
\end_inset 

Comment
\begin_inset Quotes erd
\end_inset 

 column may optionally be used to describe the tool.
 Any type of description is OK.
 This column is for the benefit of human readers only.

The Pocket, FMS, DIA and Comment fields are as for mill format tool files.
 The ZOFFSET field is the same as the TLO field of mill format tool files.
 The DIA is also used by the AXIS gui display.
\layout Standard

The XOFFSET field gives an offset for the X coordinate when tool length
 offsets are in effect.
 
\layout Standard

The ORIENTATION field gives the orientation of the lathe tool, as illustrated
 in 
\begin_inset LatexCommand \ref{cap:Tool-Orientations}

\end_inset 

.
 The red cross is the controlled point.
 See 
\begin_inset LatexCommand \ref{sub:Controlled-Point}

\end_inset 

.
\layout Standard

The FRONTANGLE and BACKANGLE fields are used by some user interfaces to
 display a fancy representation of the lathe tool.

In the RS274/NGC language view, a machining center maintains an array of
 numerical parameters.
 Many of them have specific uses.
 The parameter array persists over time, even if the machining center is
 powered down.
 EMC2 uses a parameter file to ensure persistence and gives the Interpreter
 the responsibility for maintaining the file.
 The Interpreter reads the file when it starts up, and writes the file when
 it exits.
