Circular interpolation
The → tool moves on a circle between specified points on the contour at a given feed rate,
and the workpiece is thereby machined.
CNC
See → NC
CNC high-level language
The high-level language offers: → user-defined variables, → system variables, → macro
techniques.
COM
Component of NC control for implementing and coordinating communication.
Compensation axis
Axis whose setpoint or actual value is modified using the compensation value.
Compensation table
Table of interpolation points. It supplies the compensation values of the compensation axis
for selected positions of the basic axis.
Compensation value
Difference between the axis position measured by the encoder and the desired, programmed
axis position.
Connecting cable
Connecting cables are pre-assembled or user-assembled 2-wire cables with a connector at
each end. This connecting cable connects the → CPU to a → programming device or to other
CPUs by means of a → multi-point interface (MPI).
Continuous-path mode
The objective of continuous-path mode is to avoid substantial deceleration of the → path
axes at the part program block boundaries and to change to the next block at as close to the
same path velocity as possible.
