How to Use This Calculator
  1. Enter total cutting toolpath length (mm or in), average feed rate (mm/min or IPM), and number of passes.
  2. Set total rapid traverse distance, rapid speed, and number of tool changes.
  3. Enter any additional fixturing or inspection delays.
  4. Review total cycle time, cutting time percentage, and parts per hour output.
  5. Use parts-per-hour to validate your production rate against customer demand.

Number of Tool Changes
Number of tool changes per part.
Tool Change Time
Time per automatic tool change.
Load/Unload Time
Time to load raw material and unload finished part.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Total Cutting Length = 120, Average Feed Rate = 60, Number of Passes = 3, Total Rapid Distance = 200 = 8 input(s) provided
  2. Calculate Total Cycle Time
    Total Cycle Time
    7.08 = 7.08
  3. Calculate Parts per Hour
    Parts per Hour
    8.5 = 8.5
  4. Calculate Cutting Time
    Cutting Time
    6 = 6
  5. Calculate Cutting Time %
    Cutting Time %
    85 = 85
