# Description

## Task of the coordinate system

The programming coordinate system (PCS) can be offset and rotated with respect to the machine coordinate system (MCS) by selecting a coordinate system (CS) (see figure below). This enables easy NC programming even in slanted or twisted positions.

## Notice

NC program coordinates refer to the PCS.

## Offsets

When a coordinate system is selected, an additional offset of the PCS is generated. The following offsets are available in the CNC system:

- Offsets due to selection of a coordinate system
- Offsets due to a measurement run
- Offsets due to manual operation with parallel interpolation
- Offsets due to setting an actual value
- Reference point offsets
- Tool offsets
- Zero offsets
- Clamping offsets
