Baud rate
Rate of data transfer (bits/s).
Blank
Workpiece as it is before it is machined.
Block
"Block" is the term given to any files required for creating and processing programs.
Block search
For debugging purposes or following a program abort, the "Block search" function can be
used to select any location in the part program at which the program is to be started or
resumed.
Booting
Loading the system program after power ON.
C axis
Axis around which the tool spindle describes a controlled rotational and positioning motion.
C spline
The C spline is the most well-known and widely used spline. The transitions at the
interpolation points are continuous, both tangentially and in terms of curvature. 3rd order
polynomials are used.
Channel
A channel is characterized by the fact that it can process a → part program independently of
other channels. A channel exclusively controls the axes and spindles assigned to it. Part
program runs of different channels can be coordinated through → synchronization.
Circular interpolation
The → tool moves on a circle between specified points on the contour at a given feedrate,
and the workpiece is thereby machined.
