982 is the example result. Read it using the units and relationship stated below.
CNC Cost uses setup hours, machine hours, machine hourly rate.
Keeping feed calculations attached to the cutting conditions
For cnc cost, the relationship is Result = [Setup hours] + [Machine hours] × [Machine hourly rate] + [Material cost]. The amount depends on the supplied setup hours, machine hours, 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 hours] + [Machine hours] × [Machine hourly rate] + [Material cost] 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 hours: 2; Machine hours: 8; Machine hourly rate: 85; Material cost: 300. Result: 982. The values are illustrative.
Compare one changed input
Setup hours changes from 2 to 2.2. The result becomes 982.2. All other inputs remain fixed.
Calculation rule
Result = [Setup hours] + [Machine hours] × [Machine hourly rate] + [Material cost]
Inputs and output
| Input | Example value | Entry convention |
|---|---|---|
| Setup hours | 2 | Use the duration unit stated in setup hours. A time period is not interchangeable with a currency amount or a count of events. |
| Machine hours | 8 | Use the duration unit stated in machine hours. A time period is not interchangeable with a currency amount or a count of events. |
| Machine hourly rate | 85 | Use the source quantity represented by machine hourly rate. Keep the counted population fixed and avoid mixing a unit value with a period total. |
| Material cost | 300 | Use material cost on the currency and period basis shown by the formula. Keep gross amounts, net amounts and unit amounts distinct; the page does not fetch a price or exchange rate. |
Output: 982 is the example result. Read it using the units and relationship stated below. Use the formula to distinguish a cash amount, count, percentage or ratio.
How to use the page
Collect the inputs
Gather Setup hours, Machine hours, Machine hourly rate. Use one period and the units shown in the form.
Run the calculation
Enter the values and select the action. The calculation rule above explains how the inputs produce the result.
Compare a scenario
Change Setup hours on its own, keeping the other inputs fixed. Read both results before changing another assumption.
Worked example
With the example inputs listed above, the result is 982.
Change Setup hours from 2 to 2.2 while keeping every other value fixed. The result becomes 982.2. This comparison isolates that input; it does not forecast how other variables will respond.
Check the stated formula, units and limits before using the result in a decision.
Keep the displayed formula, input units and model scope with the result. Corrections or questions can be sent through the request section on this page.
