1,150 is the example result. Read it using the units and relationship stated below.
CNC Batch Cost uses parts, cycle minutes per part, machine rate per hour.
Keeping feed calculations attached to the cutting conditions
For cnc batch cost, the relationship is Result = [Material for batch] + [Setup cost] + [Parts] × ([Cycle minutes per part] ÷ 60) × [Machine rate per hour]. The amount depends on the supplied parts, cycle minutes per part, 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 = [Material for batch] + [Setup cost] + [Parts] × ([Cycle minutes per part] ÷ 60) × [Machine rate per hour] 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
Parts: 50; Cycle minutes per part: 12; Machine rate per hour: 75; Material for batch: 300; Setup cost: 100. Result: 1,150. The values are illustrative.
Compare one changed input
Parts changes from 50 to 55. The result becomes 1,225. All other inputs remain fixed.
Calculation rule
Result = [Material for batch] + [Setup cost] + [Parts] × ([Cycle minutes per part] ÷ 60) × [Machine rate per hour]
Inputs and output
| Input | Example value | Entry convention |
|---|---|---|
| Parts | 50 | Use the source quantity represented by parts. Keep the counted population fixed and avoid mixing a unit value with a period total. |
| Cycle minutes per part | 12 | Use the duration unit stated in cycle minutes per part. A time period is not interchangeable with a currency amount or a count of events. |
| Machine rate per hour | 75 | Use the source quantity represented by machine rate per hour. Keep the counted population fixed and avoid mixing a unit value with a period total. |
| Material for batch | 300 | Use the source quantity represented by material for batch. Keep the counted population fixed and avoid mixing a unit value with a period total. |
| Setup cost | 100 | Use setup 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: 1,150 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 Parts, Cycle minutes per part, Machine rate per hour. 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 Parts 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 1,150.
Change Parts from 50 to 55 while keeping every other value fixed. The result becomes 1,225. 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.
