Coordinate transformation via frame variables

Function
In addition to the programming options already described in the Programming Guide
"Fundamentals", you can also define coordinate systems with predefined frame variables.
The following coordinate systems are defined:
MCS: Machine coordinate system
BCS: Basic coordinate system
BZS: Basic origin system
SZS: Settable zero system
WCS: Workpiece coordinate system
What is a predefined frame variable?
Predefined frame variables are keywords whose use and effect are already defined in the
control language and that can be processed in the NC program.
Possible frame variable:
• Basic frame (basic offset)
• Settable frames
• Programmable frame
