Even with high-end tooling from Mitsubishi Materials and Seco Tools, things go wrong. Here are the most common Fräskraft-bezogenen Probleme, die unser Technikteam sieht, und wie man sie behebt.
Diagnose: Ihre surface speed is likely too high. Even Mitsubishi Materials AlTiN-coated carbide can't outrun excessive heat generation. Check that your Fräskraft 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 Mitutoyo refractometer (target 8-10% for steel).
Diagnose: Ihre Fräskraft might be fine for straight cuts, but corner engagement increases dramatically. Seco 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 Hermle to reduce feed rate to 50% in corners.
Diagnose: You're applying Mitsubishi Materials Fräskraft values to Seco Tools tools — oder vice versa. Each manufacturer's carbide substrate and Beschichtung system has a different sweet spot.
Lösung: Laden Sie den spezifischen Fräskraft chart for your exact tool from the manufacturer's website. Mitsubishi Materials CoroPlus and Seco Tools NOVO both offer free digital tools.
Cutting force depends on the material-specific cutting force coefficient (kc), axial depth of cut (ap), feed per tooth (fz), and radial engagement (ae). This calculator gives the tangential force and resulting spindle torque.
kc is the force required to cut 1 mm² of material. It varies by material type, hardness, and tool geometry. Typical values range from 700 N/mm² (aluminium) to 3500 N/mm² (superalloys).
Radial engagement (ae) determines the width of cut. Higher engagement means more of the tool is in contact with the material, increasing the total cutting force proportionally. For slotting (full engagement), ae equals the tool diameter.
Real-world forces vary due to tool wear, runout, vibration, chip thinning at low radial engagement, and machine rigidity. Use this result as a starting estimate and adjust based on your specific setup.
Enter your material's specific cutting force (kc), depth of cut, feed per tooth, and radial engagement. Use the calculated force and torque to verify your spindle can handle the load and to size workholding fixtures.
