Interpolatory compensation
Interpolatory compensation is a tool that enables manufacturing-related leadscrew error and
measuring system error compensations (SSFK, MSFK).
Interrupt routine
Interrupt routines are special → subprograms that can be started by events (external signals)
in the machining process. A part program block which is currently being worked through is
interrupted and the position of the axes at the point of interruption is automatically saved.
Inverse-time feedrate
The time required for the path of a block to be traversed can also be programmed for the
axis motion instead of the feed velocity (G93).
JOG
Control operating mode (setup mode): In JOG mode, the machine can be set up. Individual
axes and spindles can be traversed in JOG mode by means of the direction keys. Additional
functions in JOG mode include: → Reference point approach, → Repos, and → Preset (set
actual value).
Key switch
The key switch on the → machine control panel has four positions that are assigned functions
by the operating system of the controller. The key switch has three different colored keys
that can be removed in the specified positions.
Keywords
Words with specified notation that have a defined meaning in the programming language for
→ part programs.
KÜ
Transformation ratio
KV
Servo gain factor, a control variable in a control loop.
Leading axis
The leading axis is the → gantry axis that exists from the point of view of the operator and
programmer and, thus, can be influenced like a standard NC axis.
