Even with high-end tooling from Gühring and Mapal, things go wrong. Here are the most common Helikale Interpolation-bezogenen Probleme, die unser Technikteam sieht, und wie man sie behebt.
Diagnose: Ihre surface speed is likely too high. Even Gühring AlTiN-coated carbide can't outrun excessive heat generation. Check that your Helikale Interpolation 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 Starrett refractometer (target 8-10% for steel).
Diagnose: Ihre Helikale Interpolation might be fine for straight cuts, but corner engagement increases dramatically. Mapal 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 Makino to reduce feed rate to 50% in corners.
Diagnose: You're applying Gühring Helikale Interpolation values to Mapal tools — oder vice versa. Each manufacturer's carbide substrate and Beschichtung system has a different sweet spot.
Lösung: Laden Sie den spezifischen Helikale Interpolation chart for your exact tool from the manufacturer's website. Gühring CoroPlus and Mapal NOVO both offer free digital tools.
Helical interpolation (helical boring) combines circular interpolation with a simultaneous Z-axis feed to create or enlarge bores with a single tool. The tool follows a helical path — a circle with a vertical pitch per revolution.
Helical interpolation is faster for roughing bores and works with standard end mills. Use it for bores that don't require boring-head precision, or to rough out a bore before finishing. For tolerances under IT7, finish with a boring head or reamer.
The bore must be at least 1.05× the tool diameter to allow the tool to enter. For practical cutting, bore should be at least 1.2× tool diameter. Below that, the tool rubs on the bore wall and chip evacuation is poor.
G02/G03 with X, Y, Z, I, J (or R) on the same line. Example: G03 X0 Y0 Z-2.0 I10 J0 F500 — makes one full helix of 2 mm depth with 10 mm radius. Use multiple lines to stack helices for deeper bores.
Enter the bore diameter, tool diameter, depth per revolution, and ramp angle. The calculator shows the helical path radius and the compensated feed rate to maintain the correct chip load at the tool centre.
