Fast retraction from
contour
When an interrupt arrives a motion can be initiated via the CNC
machining program which allows the tool to be quickly retracted from
the workpiece contour currently being machined. The angle of
retraction and the absolute value of the path can also be
parameterized. An interrupt routine can also be executed following the
fast retraction of the tool. (SINUMERIK FM-NC, 840D).
Feed override
The programmed velocity is overridden by the current velocity setting
via the machine control panel or by the PLC (0-200 %). The feedrate
can also be corrected by a programmable percentage factor (1 -
200%) in the machining program.
File type
Possible types of data, e.g. parts programs, zero offset, R parameters
etc.
Finished-part contour
Contour of the finished workpiece. See also -> blank.
Fixed machine point
A point defined uniquely by the machine tool, e.g. the reference point.
Fixed-point approach
Machine tools can approach fixed points such as a tool change point,
loading point, pallet change point, etc. in a defined way. The
coordinates of these points are stored in the control. Where possible,
the control moves these axes in -> rapid traverse.
Focus
Frame (bold surround) which indicates the windows which can be
edited.
Frame
frame is an arithmetic rule that transforms one Cartesian coordinate
system into another Cartesian coordinate system. A frame contains
the components -> zero offset, -> rotation, -> scaling, -> mirroring.
G
General reset
During a general reset the following memories of the -> CPU are
deleted:
• the -> working memory
• the read/write area of the -> load memory
• the -> system memory
• the -> backup memory
Geometry
Description of a -> workpiece in the -> workpiece coordinate system..
Geometry axis
Geometry axes are used to describe a 2- or 3-dimensional range in
the workpiece coordinate system.
