Basic Coordinate System
Cartesian coordinate system which is mapped by transformation onto the machine
coordinate system.
The programmer uses axis names of the basic coordinate system in the → part program. The
basic coordinate system exists parallel to the → machine coordinate system if no
→ transformation is active. The difference between the two coordinate systems lies in the
→ axis identifiers.
Baud rate
Rate of data transfer (Bit/s).
Blank
Workpiece as it is before it is machined.
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
movement.
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.
Chip
"Block" is the term given to any files required for creating and processing programs.
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.
