40 minutes is the example result. Read it using the units and relationship stated below.
CNC Setup Time uses setup minutes, fixture/workholding minutes.
Keeping feed calculations attached to the cutting conditions
For cnc setup time, the relationship is Result = [Setup minutes] + [Fixture/workholding minutes]. The amount depends on the supplied setup minutes, fixture/workholding minutes, rather than a live market price or a value imported from another record. A machining relationship connects diameter, speed, feed and engagement. It does not choose a safe starting point without the cutter, material and setup. Manufacturer cutting data should provide the process assumptions used in the form.
What the model includes
Result = [Setup minutes] + [Fixture/workholding minutes] Keep millimetres and metres distinct, and record whether feed is per tooth, per revolution or per minute. A correct conversion can still be unsuitable when tool reach, workholding, machine limits or chip evacuation changes. Use the result as a conversion or comparison, then validate the process against the tool guidance and machine capability. This page does not replace a tested setup sheet or account for every cutting condition.
Example with the supplied inputs
Setup minutes: 30; Fixture/workholding minutes: 10. Result: 40 minutes. The values are illustrative.
Calculation rule
Result = [Setup minutes] + [Fixture/workholding minutes]
Inputs and output
| Input | Example value | Entry convention |
|---|---|---|
| Setup minutes | 30 | Use the duration unit stated in setup minutes. A time period is not interchangeable with a currency amount or a count of events. |
| Fixture/workholding minutes | 10 | Use the duration unit stated in fixture/workholding minutes. A time period is not interchangeable with a currency amount or a count of events. |
Output: 40 minutes is the example result. Read it using the units and relationship stated below. Unit: minutes.
