Tc = L / Vf
50 / 100 = 0.5 min
Total time
0.5 × 1 = 0.5 min
ⓘ Theoretical time engaged in material, calculated at constant feed.
Defining travel
Which length should I enter?
Enter the distance actually traveled at cutting feed. For drilling, include approach and drill-point breakthrough when relevant. For turning and milling, include toolpath entry and exit.
Proper use
Cutting time or cycle time?
The result is time in cut. An industrial cycle time must add rapid moves, tool changes, inspection, loading and other auxiliary time.
