The quote handoff carries your inputs and assumptions. Only an explicit base cost is suggested as a quote cost; prices, rates and measurements remain planning notes.
Choose the tool and check the setup
Understand the cutting profile, material reference and equipment limits before applying the result.
Method & assumptions
Cutting minutes = toolpath length per pass × passes ÷ feed rate. Part time adds non-cutting minutes; batch time = part time × quantity + one-time setup.
- Enter tool-center travel for one pass, not just the part perimeter. The same path and feed are assumed for each pass.
- Acceleration, corners, rapids, probing and tool changes are not simulated. Add measured non-cutting time and confirm against CAM simulation.
