Significance
TRANSMIT
Activates the first declared TRANSMIT function
(see section "Milling on turned parts: TRANSMIT")
PTPG0
Point to Point G0 (point-to-point motion automatic at each G0 block and then
set CP again)
Because STAT and TU are modal, the most recently programmed value
always acts.
PTP
Point To Point; (point to point motion)
For TRANSMIT, PTP means that in the Cartesian spirals will be retracted to
Archimedean spirals either about the pole or from the pole. The resulting tool
motions run significantly different as for CP and are represented in the
associated programming examples.
STAT=
Resolving the non-uniqueness with regard to the pole.
TU=
TU is not relevant for PTP with TRANSMIT
