Pick and Place Options
Process-level Options
The Pick and Place process provides the following options:
• Time to Unload the Assembly Fixture: time to unload the finished assembly at the end of the assembly process. By default this is looked up by component weight (sum of the weights of the assembly’s components) in the lookup table
unloadWeldmentAllowance. You can override the default and specify the time explicitly. This value contributes to cycle time (see
Process Cycle Time Calculation). Select one of the following options:
o Use weight based computed value: this is the default.
o User override value for this part: enter a value greater than or equal to 0.
• Number of Operators: by default this is the value of the machine property Number of Operators. You can override the default and specify a different number of operators, including a fractional number of operators.
Note that labor time is independent of number of operators (see
Pick and Place Accounting Calculations), and cycle time is inversely proportional to the number of operators (see
Process Cycle Time Calculation).
This PSO specifies the total number of operators performing pick and place tasks, including any Robotic MIG Welding operators who perform pick and place tasks--see
Robotic MIG Welding Process-level Options for more information.
Select one of the following options:
o Default number of operators: the value of the machine property Number of Operators (1 in aPriori starting point VPEs)
o User override value for this part: enter a value greater than or equal to 0.
Operation-level Options
You can specify per-subcomponent values with the options listed below.
The Clamp operation provides the following option:
• Clamping Time: time to clamp the part in the fixture for subsequent operations. By default this is looked up by assembly weight (see
Assembly Weight) in the lookup table
xtraLoadTime (see
Clamp Operation Cycle Time Calculation). You can override the default and specify a time explicitly. Select one of the following options:
o Computed clamping time: This is the default.
o User override clamp time for this part: enter a numeric value.
The Load operation provides the following options:
• Base Load Time: contributes to
Load Operation Cycle Time Calculation. By default this is looked up by assembly weight (see
Assembly Weight) in the lookup table
componentLoadTime. You can override the default and specify the time explicitly. Select one of the following options:
o Computed base load time: this is the default.
o User override base load time for this part: enter a numeric value.
• Load time multiplier for handling difficulties: factor to account for additional time for handling difficulties such as nesting, stickiness, fragility, and so forth. It contributes to
Load Operation Cycle Time Calculation. By default this factor is 1. You can override the default with this PSO. Select one of the following:
o No additional time for handling difficulties: this is the default.
o Standard handling difficulties multiplier: use the value of the cost model variable handlingMultiplier (1.15 in aPriori starting point VPEs).
o User override multiplier for this part: enter a numeric value.
• Load time multiplier for insertion difficulties: factor to account for additional time for difficulties with alignment and positioning, due to obstructed access or vision, or lack of alignment features such as chamfers and lead-ins. It contributes to
Load Operation Cycle Time Calculation. By default this factor is 1. You can override the default with this PSO. Select one of the following:
o No additional time for insertion difficulties: this is the default.
o Standard insertion difficulties multiplier: use the value of the cost model variable insertionMultiplier (1.2 in aPriori starting point VPEs).
• User override multiplier for this part: enter a numeric value.
The Reorient operation provides the following options:
• ReOrient - Turn Assembly Over: contributes to
Reorient Operation Cycle Time Calculation. By default this is the value of the cost model variable
reorientTime (9 seconds in aPriori starting point VPEs). You can override the default and specify the time explicitly. Select one of the following options:
o Standard time: this is the default.
o User override base load time for this part: enter a numeric value.
