Bench Operation Process

The Bench Operation process occurs twice in Composites routings. Each occurrence has a single, component-level, child operation:

• One occurrence includes the Tool Breakdown component-level operation, which models moving the part and tooling into the work cell, removing the vacuum bag and part, and moving the empty tooling out of the work cell.

• The other occurrence includes the Inspecting component-level operation, which models visually inspecting the finished part

Labor Time =

(Labor Dependent Process Time * Labor Time Standard) +

Part Handling Labor Time

Labor time depends on the following:

• Labor-dependent process time: this is the sum of the Labor Dependent Process Time for Tool Breakdown (vacuum bag removal) and the Labor Dependent Process Time for Inspecting (total inspection labor time). See Tool Breakdown Component-level Operation and Inspecting 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.

• Part handling labor time (see formula)

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 value of the formula Part Handling Time for the Tool Breakdown 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.

Part Handling Labor Time = Part Handling Elapsed Time * Number of Operators

Part handling labor time is the product of the following:

• Part handling elapsed time: this is the value of the formula Part Handling Time for the Tool Breakdown Component-level Operation.

• Number of operators: specified by the machine property Number of Operators.
