Overview

Task

By selecting a coordinate system (referred to as CS), the programming coordinate system (PCS) can be offset and rotated relative to the machine coordinate system (MCS). This permits simple NC programming even in slanted or twisted positions.

Offsets, e.g. zero offsets, can also be regarded as selecting a coordinate system.

Characteristics

Coordinate systems (CS) and offsets are always active from selection through to deselection or when offset parameters are changed. The offsets additionally programmed while a coordinate system is active are only valid until the coordinate system is deselected.

Programming and parameterisation

Some of the offsets can be defined in the NC program. They include the following:

• Offsets due to a coordinate system selection (#CS)
• Offsets due to a measurement run (G100)
• Offsets from position presets (#PSET)
• Reference point offsets (G92)
• Offsets due to manual mode in conjunction with parallel interpolation (/G202)

The following offsets are preset in configuration lists. They can be used directly in the NC program (G54..., D..). It is also possible to use the edit option during program runtime.

• Tool offsets: Parameterising using the tool parameter list [TOOL] or variable access (V.G.)
• Zero offsets: Parameterising using the zero point data list [ZERO] or variable access (V.G.)
• Clamping position offsets: Parameterisation by means of the clamp position offset data list [CLMP]
