Siemens alarm 10758: Channel %1 block %2 curvature radius with variable compensation value too small

What it means

With continuously changing compensation values, monitoring found an inner contour whose curvature radius is smaller than the current effective tool radius. The tool would gouge the material, so execution stops. Use a smaller tool or soften the contour geometry.

Likely causes

• Tool radius exceeds smallest inner radius of the curve
• Corner radii reduced by CHF/RND below the tool radius
• Compensation value changed across a tight inner arc
