All axes defined and programmed via machine data:

are traversed along path sections of identical size with SPP and SPN until the programmed
end point is reached. This also applies to rotatable tool axes if programmed. The response
can be adjusted for single axes.

; Position with reduced SPP value, because travel
; distance < SPP value, and initiate punch after
