With regard to the Sequence Clearance “Start and END Point” I would like to have access to the: table repeat region Report Symbol, the “Machine Tool Setup PPRINT” and/or the “Parameter UI” option.
The justification for this manufacturing request is safety and NC Program accountability. Certain (Mazak) 5-axis machine tools utilize Tool Center Point Control (TCP) (G43.4) to translate the tool-tip path defined in the part program into the position and orientations for the machine’s linear and rotary axes. Within particular zones of the rotary axis the tool pivot motions will translate without issue but other (particular 180 degree) translations of the tool vector will whip the tool into the machine or the part. A simple solution to insure a controlled rotation is to start and end each Sequence at a common (safe) rotary centerline. I typically name this point “PT_43-4_ROT.” I would like to have this Start and End point flagged as a double check in the Operation Sheet manufacturing repeat region Report Symbol table and within the comments of the posted program with the “Machine Tool Setup PPRINT” and/or “Parameter UI” option.
