# Splitting up motion path and programming (#STROKE DEF, #PUNCH ON/OFF, #NIBBLE ON/OFF)

The motion path is split up either by specifying the length of a partial segment or the number of partial segments. Programming is modal.

Splitting up by specifying the length of a partial segment takes place so that the travel block is uniformly subdivided into partial segments. The length of each real partial segment is less than or equal to the length of the programmed partial segment.

When the motion path is split up by specifying the number of partial segments, the segment length is calculated automatically.

Splitting up linear blocks

Programmed circular blocks are converted to linear partial motions and splitting of the motion path refers to the arc length of the circle.

Splitting up circular blocks

To define the reciprocating motion, a sequence limited to a maximum of 10 blocks is programmed, which is delimited with the following two commands:

Syntax of Defining stroke motion:
#STROKE DEF BEGIN | Start of stroke definition
#STROKE DEF END | End of stroke definition

Only the following restricted scope of functions is allowed for stroke definition:

#STROKE DEF BEGIN

G0, G01, M, H, G261, G61, G260, G60, G04, #TIME, G90, G91

#STROKE DEF END

## Notice

The use of any other NC commands within the stroke definition leads to an error.

Syntax of Activating/deactivating punching and nibbling functions:
#PUNCH ON | OFF [ [LENGTH=.. | NUMBER=..] ]
#NIBBLE ON | OFF [ [LENGTH=.. | NUMBER=..]

ON | Activate punching/nibbling
OFF | Deactivate punching/nibbling
LENGTH=.. | Length of a partial segment after which a stroke motion is automatically inserted in [mm, inch]. With #NIBBLE ON, a stroke motion is executed during the first path motion in the active machining plane, including at the start.
NUMBER=.. | Number of partial segments to be generated within one motion command. A stroke motion is triggered after every partial segment.

## Notice

LENGTH and NUMBER are exclusive, i.e. splitting up is based either on partial segment length or the number of partial segments.
