Punching and nibbling on the spot
A stroke is initiated only if the block contains traversing information for the punching or
nibbling axes (axes in active plane).
However, to initiate a stroke at the same position, one of the punching/nibbling axes can be
programmed with a traversing path of 0.
Machining with rotatable tools
Note
Use the tangential control function if you wish to position rotatable tools at a tangent to the
programmed path.
Use of M commands
As in earlier versions, macro technology allows special M functions to be used instead of
language commands (compatibility). The M functions and equivalent language commands as
used in earlier systems are as follows:
M20, M23
≙
SPOF
M22
≙
SON
M25
≙
PON
M26
≙
PDELAYON
Example for macro file:
