Threaded Insert Formulas
Cycle Time = Final Threaded Insert Insert Time + Final Tang Break Time
The Threaded Insert operation models three tasks:
• Threaded Insert placement: insertion of the threaded insert before the tang is broken.
• Tang breaking: the tang blocks the hole during insertion; it must be removed subsequent to insertion.
Consequently, cycle time is the sum of the following:
• Final threaded insert insert time: this is the time to insert the threaded insert, including any extra time required due to vision difficulties or obstructions. See formula.
• Final tang break time: this is the time to break the tang, including any extra time required due to vision difficulties or obstructions. See formula.
Final Threaded Insert Insert Time =
Threaded Insert Insert Time + Threaded Insert Insert Extra Time
The final time to insert the threaded insert is the sum of the following:
• Threaded insert insert time: time to insert the threaded insert, not including any extra time required due to vision difficulties or obstructions. This is specified by the machine property Insert Time (4 seconds for the default machine in starting point VPEs).
• Threaded insert insert extra time: this accounts for any extra time required, due to an obstruction or vision problem, to insert the threaded insert. The extra time is looked up in the lookup table tblMechanicalOperationTimes by the following:
o Process name ('Threaded Insert')
o Task name ('Threaded Insert Op')
o Setting of the PSO Threaded Insert Obstructed Or Vision.
The extra time is 0 if the PSO setting is No obstructed access or vision problem (the default in starting point VPEs).
Final Tang Break Time = Tang Break Time + Tang Break Extra Time
Final tang break time is the sum of the following:
• Tang break time: this is the time to break the tang, in the absence of obstructions or vision difficulties. It is looked up by process name ('Threaded Insert') and task name ('Tang Break') in the lookup table tblMechanicalOperationTimes (1 second in starting point VPEs).
• Tang break extra time: this accounts for any extra time required to break the tang due to an obstruction or vision problem. The extra time is looked up in the lookup table tblMechanicalOperationTimes by the following:
o Process name ('Threaded Insert')
o Task name ('Tang Break')
o Setting of the PSO Tang Break Obstructed Or Vision.
The extra time is 0 if the PSO setting is No obstructed access or vision problem (the default in starting point VPEs).
