If you have a 5-axis or 3+2 machine with the 828D, the post must manage (tool orientation management). Without it, rotary moves are dangerous. The post must insert TRAORI at the start of multi-axis paths and TRAFOOF at the end, then manage the kinematic chain.
For 828D swivel heads or rotary tables, the post must output TRAORI (activate TCPM) and TRAFOOF . Additionally, mill-turn posts require TRANSMIT for cylindrical mapping. Mastercam’s Generic Fanuc 5X Mill.pst cannot handle this—you need a Siemens-specific 5-axis post that processes M128 (Siemens’ TCPM code). siemens 828d post processor for mastercam
