Even with high-end tooling from OSG and Iscar, things go wrong. Here are the most common Interpolación Helicoidalque nuestro equipo técnico ve, y cómo solucionarlos.
Diagnóstico: Su surface speed is likely too high. Even OSG AlTiN-coated carbide can't outrun excessive heat generation. Check that your Interpolación Helicoidal coincida con la dureza real del material — un cambio de HRC 28 a HRC 32 en 4140 lo cambia todo.
Solución: Reduce SFM by 15-20%. Verify coolant concentration with a Mahr refractometer (target 8-10% for steel).
Diagnóstico: Su Interpolación Helicoidal might be fine for straight cuts, but corner engagement increases dramatically. Iscar application engineers call this the "corner trap" — the tool sees 180° of engagement in a 90° internal corner.
Solución: 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.
Diagnóstico: You're applying OSG Interpolación Helicoidal values to Iscar tools — o vice versa. Each manufacturer's carbide substrate and recubrimiento system has a different sweet spot.
Solución: Descargue la tabla específica de Interpolación Helicoidal chart for your exact tool from the manufacturer's website. OSG CoroPlus and Iscar 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.
