Auxiliary functions
Auxiliary functions enable part programs to transfer → parameters to the → PLC, which then
trigger reactions defined by the machine manufacturer.
axes
In accordance with their functional scope, the CNC axes are subdivided into:
•
Axes: interpolating path axes
•
Auxiliary axes: non-interpolating feed and positioning axes with an axis-specific feed rate.
Auxiliary axes are not involved in actual machining, e.g., tool feeder, tool magazine.
Axis address
See → Axis identifier
Axis identifier
Axes are identifed using X, Y, and Z as defined in DIN 66217 for a right-handed, right-angled
→ coordinate system.
Rotary axes rotating around X, Y, and Z are identified using A, B, and C. Additional axes
situated parallel to the specified axes can be designated using other letters.
Axis name
See → Axis identifier
Backlash compensation
Compensation for a mechanical machine backlash, e.g., backlash on reversal for ball
screws. Backlash compensation can be entered separately for each axis.
Backup battery
The backup battery ensures that the → user program in the → CPU is stored so that it is safe
from power failure and so that specified data areas and bit memory, timers and counters are
stored retentively.
Base axis
Axis whose setpoint or actual value position forms the basis of the calculation of a
compensation value.
Basic Coordinate System
Cartesian coordinate system which is mapped by transformation onto the machine
coordinate system.
