Contour of the finished workpiece. See also -> Blank.
A frame is a calculation rule that translates one Cartesian coordinate
system into another Cartesian coordinate system. A frame contains
the components -> zero offset, -> rotation, -> scaling, -> mirroring.
Inside the cycle, additive frames programed, which have an effect on
the actual-value display during the cycle.
After the cycle, the same workpiece coordinate system is active as
before the call.
Geometry axes are used to describe a 2 or 3-dimensional area in the
workpiece coordinate system.
Each global main program/subroutine may appear only once under its
name in the directory. It is not possible to use the same program
name in different directories with different contents as a global
program.
Words in compliance with DIN 66025 are supplemented by identifiers
(names) for variables (arithmetic variables, system variables, user
variables), for subroutines, for keywords and for words with several
address letters. These supplements have the same meaning as the
words with respect to block format. Identifiers must be unambiguous.
It is not permissible to use the same identifier for different objects.
Measurement system which defines distances in "inches" and
fractions of inches.
Control operating mode (setup operation): The machine can be set up
in the Jog mode. Individual axes and spindle can be traversed in jog
mode by means of the direction keys. Other functions which are
executed in jog mode are -> reference point approach, -> REPOS and
-> preset (set actual value).
