aPriori uses the formulas below to determine costs associated with these processes.
Accounting Calculations
Labor Time = Cycle Time * Number of Operators
Labor time is the product of the following
• Machine labor time standard (specified as a machine property). This value reflects the amount of time spent by machine operators in between machine cycles, including time performing maintenance and cleaning tasks as well as time pausing between tasks. The amount is expressed as a cycle time multiplier.
Labor Cost = (Labor Time + 1 / 3600) * Machine Labor Rate
Labor cost is a function of the following:
• Labor time (see formula above)
• Machine labor rate (specified as a machine property)
Amortized Batch Setup = (Machine Setup Time * (Machine Labor Rate + Direct Overhead Rate)) / Batch Size
Amortized batch setup cost depends on the following:
• Machine setup time (specified as a machine property)
• Machine labor rate (specified as a machine property)
• Direct overhead rate (see
Direct and Indirect Overhead)
• Batch size (specified in the Production Info dialog)
Cycle Time Calculation
Cycle Time = Cut Time + Pierce
Cycle time depends on the following:
• Cut time, which is the product of the following:
o Part perimeter (obtained from GCD extraction)
o Laser feed rate (based on lookup in sm3DLaserCutRate by power requirement)
• Pierce time (based on lookup in sm3DLaserCutRate by power requirement)
Tolerance capability by hole diameter is contained in the lookup table toleranceCapability.
