Hand Layup Process

Labor Time = Labor Dependent Process Time * Labor Time Standard

Labor time depends on the following:

• Labor-dependent process time: this is the sum of the values of Labor Dependent Process Time for all child operations and processes--see the following sections:

o Ply Placing Operation for Hand Layup

o Core Potting Operation for Hand Layup

o Core Splicing Operation for Hand Layup

o Core Placing Operation for Hand Layup

o Vacuum Bag Process

o Remove Vacuum Bag Component-level Operation

o Final Vacuum Bag Process

o 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.

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: sum of the vacuum drop test hold time and the debulk times for child operations. See Vacuum Bag Drop Test Component-level Operation and Debulk Component-level Operation.

• Labor-dependent process time: this is the sum of the values of Labor Dependent Process Time for all child operations and processes. See the Labor Time formula, above.

• 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.

Material Cost

This is the sum of the core and ply material costs for all child operations. See Ply Placing Operation for Hand Layup and Core Placing Operation for Hand Layup.
