Even with high-end tooling from Sumitomo Electric and Walter Tools, things go wrong. Here are the most common Metallgewicht & -kosten-bezogenen Probleme, die unser Technikteam sieht, und wie man sie behebt.
Diagnose: Ihre surface speed is likely too high. Even Sumitomo Electric AlTiN-coated carbide can't outrun excessive heat generation. Check that your Metallgewicht & -kosten zur tatsächlichen Materialhärte passt — ein Wechsel von HRC 28 auf HRC 32 bei 4140 ändert alles.
Lösung: Reduce SFM by 15-20%. Verify coolant concentration with a Renishaw refractometer (target 8-10% for steel).
Diagnose: Ihre Metallgewicht & -kosten might be fine for straight cuts, but corner engagement increases dramatically. Walter Tools application engineers call this the "corner trap" — the tool sees 180° of engagement in a 90° internal corner.
Lösung: Add a finish pass at 0.1mm radial depth with a separate finishing tool. Program the Starrag to reduce feed rate to 50% in corners.
Diagnose: You're applying Sumitomo Electric Metallgewicht & -kosten values to Walter Tools tools — oder vice versa. Each manufacturer's carbide substrate and Beschichtung system has a different sweet spot.
Lösung: Laden Sie den spezifischen Metallgewicht & -kosten chart for your exact tool from the manufacturer's website. Sumitomo Electric CoroPlus and Walter Tools NOVO both offer free digital tools.
Material cost is often the largest single component of a machined part cost. This calculator multiplies the part weight by the material unit price, with an estimate for the number of parts produced from the material input.
Titanium (Grade 5/Ti-6Al-4V) at $30-50/kg. Inconel 718 at $40-60/kg. Tungsten carbide blanks at $80-200/kg. At the low end: mild steel at $1-2/kg, aluminium 6061 at $3-5/kg. Prices fluctuate with commodity markets and order quantity.
Typical buy-to-fly ratios: 4:1 to 10:1 meaning 75-90% of the purchased material becomes chips. For simple parts from bar stock, 15-30% waste. For complex aerospace structural parts machined from plate, 85-95% waste. Use the scrap value calculator to offset some of this cost.
Calculate the blank weight (not finished part weight), multiply by material price, then divide by estimated parts per blank. Compare the total including tooling cost, cycle time, and scrap. The cheapest material is not always the lowest cost per part if it machines slowly or wears tools quickly.
Enter the material weight in kg and the price per kg. The calculator shows the total material cost and an estimated cost per part. For accurate quoting, add waste allowance, shipping, and minimum order quantity surcharges to the base material cost.
