Moving to positions in a non-tilted coordinate
system with a tilted working plane: M130
Standard behavior with a tilted working plane
The TNC references coordinates in the positioning blocks to the
tilted coordinate system.
Behavior with M130
The TNC references coordinates in straight line blocks with an
active tilted working plane to the untilted coordinate system.
The TNC then positions the (tilted) tool to the programmed
coordinates of the untilted system.
Danger of collision!
Subsequent positioning blocks or fixed cycles are
carried out in a tilted coordinate system. This can
lead to problems in fixed cycles with absolute pre-
positioning.
The function M130 is allowed only if the tilted
working plane function is active.
Effect
M130 functions blockwise in straight-line blocks without tool radius
compensation.
