Automated Tape Layup Process
Labor Time =
(Labor Dependent Process Time * Labor Time Standard) +
Layup Time
Labor time depends on the following:
• Labor-dependent process time: this is the value of
Labor Dependent Process Time for Attach Thermocouples—see
Attach Thermocouples Component-level Operation.
• Labor time standard: specified as the machine property Labor Time Standard. This multiplier is used to account for otherwise unaccounted for factors that affect labor time, such as operator fatigue or time spent by the operator for cleaning or maintenance.
• Layup time: this is the sum of the values of
Layup Time for the child operations on the part’s plies. One operator is assumed to oversee the layup operations. See
Ply Placing Operation for Automated Tape Layup.
Cycle Time =
(Labor Independent Process Time +
(Labor Dependent Process Time / Number of Operators)) *
Cycle Time Adjustment Factor
Cycle time depends on the following:
• Labor independent process time: this is the vacuum drop test hold time plus the sum of the layup times for all plies. See
Vacuum Bag Drop Test Component-level Operation and
Ply Placing Operation for Automated Tape Layup.
• Labor dependent process time: this is the value of
Labor Dependent Process Time for Attach Thermocouples—see
Attach Thermocouples Component-level Operation.
• Number of operators: by default, this is specified by the machine property
Number of Operators. Users can override the default on a per-part basis with the setup option
Number of Operators.
• Cycle time adjustment factor: specified by the cost model variable cycleTimeAdjustmentFactor (1 in starting point VPEs). VPE administrators can change the cost model variable to globally adjust cycle times for Composites.
Programming Cost
By default, cost to program the layup machine is specified by the cost model variable
defaultATLProgrammingCost (0 in starting point VPEs). Users can override the default on a per-part basis with the setup option
Automated Tape Layup Machine Programming Cost.
