CNC outsourced processing, quoted right.
Cylindrical grinding, surface grinding, hardening, nitriding, coating, passivation — 80+ outsourced services as reusable calculation formulas. Auto-detected from the technical drawing, auto-applied to the part.
At most CNC job shops, 30–40% of part cost doesn't come from the actual milling, turning or stamping — it comes from outsourced processing: grinding, hardening, coating, passivation, inspection.
Today this is hand-maintained: Excel sheets with €/kg rates, manual entry on every quote, forgotten minimum charges, wrong drivers. goCAD replaces that with reusable reference formulas that pull straight from the drawing — for milling, turning and sheet metal alike.
What goCAD quotes as outsourced work.
CNC grinding
Cylindrical, surface and internal grinding. Calculated from grinding area, number of increments, feed and cutting speed — including 30% tool-overrun supplement and 40% process safety factor for tool changes and wheel dressing.
Heat and hardness treatment
Vacuum hardening (up to 1100/1200 °C), plasma nitriding, gas nitriding, gas nitrocarburizing, case hardening, tempering, annealing, ageing, deep-freezing, laser hardening, induction hardening.
Surface treatment & coating
Blackening, passivation (incl. thick-layer), blasting (graded by batch), powder coating. PVD coatings like DLC and WC/C "Hardslide" sliding layers — quoted by area (€/dm²).
Pre- & post-work
Degreasing before hardening, masking / shielding for selective treatment, oxidation after nitrocarburizing, straightening after heat treatment. Fixed price per part or weight-based.
Certificates & inspections
Material certificate 3.1, spectral analysis, hardness test, coating thickness measurement, first-article inspection report (FAI). Fixed price per item, optionally graded by quantity.
Shipping & handling
Packaging, marking, intermediate transport between the shop and the service provider. Each step its own position with its own logic — no flat surcharge that hides the margin.
From drawing to quote — automatically.
You set up your outsourced-process catalog once. After that goCAD detects the relevant requirements straight from CAD and the technical drawing and applies the matching formulas to every part.
Automatic detection from the technical drawing
goCAD reads grinding symbols per DIN ISO 1302, hardness specs like HRC 60 ±2, surface specs (Ra, Rz), coating notes ("DLC 2 µm"), heat-treatment notes and inspection requirements automatically from PDF and CAD — and assigns the matching outsourced services.
Formula-based, reusable
Every process follows a clear pattern: unit_price = MAX(60 / quantity, driver × rate + handling). The minimum amount protects against losses on small batches; the variable part scales with weight, area, time or fixed price.
Straight into the quote, cross-process
The calculated outsourced service appears as its own line item in the quote — driver, rate and minimum amount transparently shown. Works identically for milling, turning and sheet metal. No more separate Excel sheets per process.
How goCAD calculates a grinding operation.
Machine occupancy time for a grinding operation is made up of three blocks: effective grinding time, secondary times (return + approach), process safety factor.
runtime = ((A_total × 1.3 × i) / (f × v_cw × 1000)
+ (i × return_time / 60)
+ (approach_time / 60))
× 1.4 Grinding time (base): 0.41 min · Secondary time (15 returns + 1 approach): 1.33 min · Subtotal 1.74 min × 1.4 safety factor = 2.44 minutes occupancy. On small areas secondary time is typically higher than the pure grinding time — that's exactly what goCAD models.
80+ reference processes, ready to go.
All rates per 2026 market level, customizable per project. Each process has its own driver (weight, area, time or fixed price) and its own minimum charge.
70+ more processes in the catalog · all formulas transparently editable per project
Works for milling, turning and sheet metal alike.
Outsourced services are modelled independently of the host process — what matters is the driver, not whether the part comes off the milling spindle or the laser cutter.
Grinding + hardening
Milled parts with precision functional surfaces combine cylindrical / surface grinding with vacuum hardening. goCAD detects hardness specs and grinding symbols, assigns the follow-up processes and quotes occupancy time + material throughput.
Cylindrical grinding + coating
Turned parts with shaft or axle function typically go from turning into cylindrical grinding and then into DLC or WC/C coating. The full process chain is reflected in the quote.
Blackening + powder coating
Sheet-metal parts that need blackening, passivation or powder coating are quoted with the same reference formulas as milled parts — the driver here is typically area, not weight.
Answers on CNC outsourced processing.
What is CNC outsourced processing?
How do you quote CNC cylindrical grinding?
runtime = ((A_total × 1.3 × i) / (f × v_cw × 1000) + (i × return_time/60) + (approach_time/60)) × 1.4. goCAD applies this formula automatically — area, increments and cutting parameters come from geometry and machine park. A 5,000 mm² part typically takes 2.44 minutes.How is CNC surface grinding quoted?
Which surface treatments can goCAD quote?
Are CNC additional processes detected from the technical drawing automatically?
Does outsourced-process quoting also work for sheet-metal parts?
