Moving to position in an non-tilted coordinate
system with a tilted working plane: M130
Standard behavior with a tilted working plane
The TNC places the coordinates in the positioning blocks in the
tilted coordinate system.
Behavior with M130
The TNC places coordinates in straight line blocks in the untilted
coordinate system
The TNC then positions the (tilted) tool to the programmed
coordinates of the untilted system.
Effect
M130 functions only in straight-line blocks without tool radius
compensationand in blocks in which M130 is programmed.
