Formulas for the Router Process
Cycle Time = Handling Time + Cutting Time
• Handling time: this is load and unload time. Each time is looked up by blank mass in the lookup table tblMaterialHandling.
• Cutting time (see formula)
Cutting Time = Tool Engaged Time + (2 * Rapid Traverse Time)
Cutting time depends on the following:
• Tool engaged time (see formula)
• Rapid traverse time (see formula)
Tool Engaged Time = (Profile Perimeter / Machine Feed Rate)
Tool engaged time depends on the following:
• Profile perimeter: this is the sum of the lengths of the blank edges.
• Machine feed rate (specified by the machine property Feed Rate)
Rapid Traverse Time = ((Part Length / 2) / Machine Rapid Traverse Rate)
Rapid traverse time depends on the following:
• Part length
• Machine rapid traverse rate (specified by the machine property Rapid Traverse Rate)
