A variable is defined through the specification of a data type and a
variable name. The variable name can be used to address the value
of the variable.
In order to achieve an acceptable travel velocity in movements which
call for very small adjustments of position in a block, the control can ->

Words with a specific notation which have a defined meaning in the
programming language for -> parts programs.
-> Zero offset
The working storage is a Random Access Memory in the -> CPU
which the processor accesses as it executes the application
program.
Three-dimensional zone into which the tool tip can be moved on
account of the physical design of the machine tool.
See also -> protection zone.
Part to be produced/machined by the machine tool.
Setpoint contour of the -> workpiece to be produced/machined.
The origin of the workpiece coordinate system is the -> workpiece
zero. In machining operations programmed in the workpiece
coordinate system, the dimensions and directions refer to this
system.
The workpiece zero forms the starting point for the ->
workpiece coordinate system. It is defined by distances to the
machine zero.
