Rivet Process Options
The Rivet Process provides the following options:
Riveted Hole Count
By default, the number of riveted holes is the sum of the following:
• Number of riveted simple holes: this is the number of SimpleHole GCDs whose diameter is within range (see below).
• Number of riveted complex holes: this is the number of ComplexHole GCDs whose MEC diameter (diameter of the largest circle that fits inside the hole) is in range.
A diameter or MEC diameter is in range if it is between the values of the following cost model variables:
• minRivetDiameter (2mm in starting point VPEs)
• maxRivetDiameter (8mm in starting point VPEs)
With this setup option, users can override the default number of riveted holes.
The number of riveted holes drives cycle time--see Rivet Process Formulas.
Rivet Obstructed Or Vision
Specifies whether there is an obstruction or vision problem that adds to the time required to rivet holes (see Rivet Process Formulas). The default setting in starting point VPEs is No obstructed access or vision problem. You can override the default and specify one of the following options:
• Obstructed access OR vision problems (adds 2.5 seconds in aPriori starting point VPEs)
• Obstructed access AND vision problems (adds 4 seconds in aPriori starting point VPEs)
The time added is looked up by the current process group, process, and PSO setting in the lookup table tblMechanicalOperationTimes. See Rivet Process Formulas.
For both this setup option, the lookup table tblProcessSetupOptionSelection lists the possible settings; the entry with 1 in the priority column provides the default for both setup options.
