6.6 Inch/metric setting
Overview
The tool database (tool cabinet and tool catalog) and code carrier support machining in inch
or mm measurements.
The behavior with respect to length units is set for the tool database or the code carrier in the
paramtm.ini file in the [TMMODES] section via the DATABASE_LENGTH_UNIT and
CODECARRIER_LENGTH_UNIT entries.
Tool database
NCK with inch/mm data conversion:
[TMMODES]
; !! NOTICE:
; The settings described here are only relevant
; if the machine data $MN_CONVERT_SCALING_SYSTEM=1 is set
; in the NCK.
; The entry for DATABASE_LENGTH_UNIT is only analyzed if
; there is no unit entered in the tool database yet.
; This means once in a normal case scenario!
; -1 means no setting for inch/metric in the tool
; database (default).
; The setting $MN_CONVERT_SCALING_SYSTEM=1 in the NCK means
; that inch/metric conversion is to be used.
; Therefore the user must determine the unit of the data in
; the tool database. With the setting -1 this
; does not occur, so all softkeys for database activities
; are disabled.
; 0 means mm.
; When a tool database is opened for the first time by a tool
management
; with inch/mm differentiation, the data concerned appear
; in the tool database in mm.
; An entry is added to the database to show that
; the tool data in the database is in
; mm.
; For data transfers between the database and NCK
; this is taken into account accordingly.
; 1 means inch
; When a tool database is opened for the first time by a tool
management
; with inch/mm differentiation, the data concerned appear
; in the tool database in inches.
; An entry is added to the database to show that
; the tool data in the database is in
; inches. For data transfers between the database and NCK
; this is taken into account accordingly.
