Process
Process determines the model for chip volume and finishing path.
Milling
Turning
Stock form
Stock shape determines volume and purchased weight.
Rectangular stock
Round stock
Length
Part length excluding stock allowance; increases weight and machining travel.
mm
Width
Part width of the rectangular envelope; affects stock weight.
mm
Height
Part height of the rectangular envelope; affects stock weight.
mm
Diameter
Outside diameter for round stock; larger values increase weight quadratically.
mm
Finished-part volume
Optional volume from a validated closed CAD model; determines material removal.
cm³
Known NC machining time
Optional time from NC analysis or CAM; replaces the material-removal estimate but is not an exact machine cycle time without control simulation.
min
Batch quantity
Number of good parts; distributes setup and programming costs across the batch.
units
Stock allowance per side
Allowance on every outside face; increases stock weight and chip volume.
mm
Purchase price
Supplier price for the material and delivery condition; material remains unresolved without a price.
€/kg
Cutting cost per blank
Sawing or cutting cost in addition to the weight-based price; increases material cost.
€/unit
Setups
Planned setups; every additional setup increases setup and auxiliary time.
Holes
Number of additional holes to machine; increases machining and programming effort.
Hole diameter
Diameter used for the estimated drilling feed rate; tool data take precedence.
mm
Hole depth
Depth per hole; longer holes increase estimated time.
mm
Part complexity
Complexity affects assumed setup, programming, and finishing times; verify against your production process.
Simple
Medium
Complex
Known machine rate
Your substantiated machine rate excluding personnel; replaces the derivation from annual costs.
€/h
Labour hourly rate
Your productive personnel cost rate; 38 euros is only an editable example.
€/h
Machine purchase price
Net acquisition cost; the difference from residual value is spread over the useful life.
€
Residual value
Expected residual value; reduces annual depreciation.
€
Useful life
Imputed useful life; more years reduce annual depreciation.
years
Productive machine hours
Actual productive hours; fewer hours increase the rate for fixed annual costs.
h/year
Maintenance and other fixed costs
Annual maintenance, insurance, and other machine costs; increase the rate.
€/year
Floor-space cost
Annual space costs allocated to the machine; increase the machine rate.
€/year
Average power draw
Average electrical power draw during production; not the maximum spindle power.
kW
Electricity price
Your energy price for electricity; multiplied by the average power draw.
€/kWh
External service
Quote for external surface treatment or inspection; a blank value means unresolved, while zero euros means intentionally none.
€/unit
Cutter diameter
Intended cutter; affects spindle speed, engagement width, and estimated material removal rate.
mm
Cutting edges
Number of effective cutting edges; more cutting edges increase theoretical feed.
Effective cutting share
Share of theoretical removal actually achieved due to approach paths and engagement; verify the initial value.
