In contrast to punching, the first stroke is made at the start point of the block with the

the program end is reached.

The stroke initiation is suppressed in blocks without traversing information relating to the

axes designated as punching or nibbling axes (typically those in the active plane). If a stroke

still needs to be initiated, then one of the punching/nibbling axes must be programmed with a

0 traversing path. If the first block with

type mentioned, then only one stroke takes place in this block since the start and end points

are identical.
