Criteria for stroke initiation

Initiate a stroke
The stroke initiation must be set, at the earliest, for the point in time at which it can be
guaranteed that the axes have reached a standstill. This ensures that at the instant of
punching, there is absolutely no relative movement between the punch and the metal sheet
in the machining plane.
The following diagram shows the various criteria that can be applied to stroke initiation.

Description
The interpolation reaches the block end. In this case,
the axes continue to move until the overtravel has
been traversed, i.e. the signal is output at an
appreciable interval before the axes have reached
zero speed (see t"
