Coordinate systems

MCS
The machine coordinate system (MCS) has the following properties:
● It is defined by the machine axes.
● The machine axes can be perpendicular to each other to form Cartesian system or arranged
in any other way.
● The names of the machine axes can be defined.
● The machine axes can be linear or rotary axes.
BCS
The basic coordinates system (BKS) has the following properties:
● The geometry axes form a perpendicular Cartesian coordinate system.
● The BCS is derived from a kinematic transformation of the MCS.
BZS
The basic zero system (BZS) is the basic coordinate system with a basic offset.
SZS
The settable zero system (SZS) is the workpiece coordinate system with a programmable
frame from the viewpoint of the WCS. The workpiece zero is defined by the settable frames
G54 to G599.
WCS
The workpiece coordinate system (WCS) has the following properties:
● In the workpiece coordinate system all the axes coordinates are programmed (parts
program).
● It is made up of geometry axes and special axes.
