Inclined surface machining
Drilling and milling operations on workpiece surfaces that do not lie in the coordinate planes
of the machine can be performed easily using the "inclined-surface machining" function.
Increment
Traversed distance information via the number of increments. The number of increments can
be stored as → setting data or be selected by means of a suitably labeled key (i.e., 10, 100,
1000, 10000).
Incremental dimension
Also incremental dimension: A destination for axis traversal is defined by a distance to be
covered and a direction referenced to a point already reached. See -> Absolute dimension.
Initialization block
Initialization blocks are special -> program blocks. They contain value assignments that are
performed before program execution. The primary purpose of initialization blocks is to
initialize predefined data or global user data.
Initialization files
It is possible to create an initialization file for each -> workpiece. Various variable
assignments which are intended to apply specifically to one workpiece can be stored in this
file.
Intermediate blocks
Motions with selected → tool offset (G41/G42) may be interrupted by a limited number of
intermediate blocks (blocks without axis motions in the offset plane), whereby the tool offset
can still be correctly compensated for. The permissible number of intermediate blocks that
the control reads ahead can be set via system parameters.
Interpolator
Logical unit of the -> NCK which determines intermediate values for the movements to be
traversed on the individual axes on the basis of destination positions specified in the parts
program.
Interpolatory compensation
The interpolatory compensation allows manufacturing related Leadscrew Error
Compensation and Measuring System Error Compensation (LEC, MSEC).
interrupt routine
Interrupt routines are special -> subroutines which can be started on the basis of events
(external signals) in the machining process. A parts program block which is currently being
worked through is interrupted and the position of the axes at the point of interruption is
automatically saved.
