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