CORNER-RADIUS RECTANGULAR POCKET ROUGHING & FINISHING CYCLE
⚙️ PARAMETRIC CORNER-RADIUS RECTANGULAR POCKET ROUGHING & FINISHING CYCLE
Professional parametric rectangular pocket machining with automatic helical entry, calculated corner-radius roughing and complete wall finishing.
Turn repetitive pocket programming into one compact, reusable CNC cycle. Define the pocket size, corner radius, cutter, depth and machining conditions — the cycle automatically calculates the complete roughing and finishing strategy.

🌀 AUTOMATIC HELICAL ENTRY
Every new depth begins with a controlled helical entry. The cutter progressively moves down in Z while performing circular X/Y interpolation, eliminating the need to manually program repeated entry movements.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
↔️ AUTOMATIC ROUGHING
The cycle automatically roughs the pocket using alternating left-to-right and right-to-left passes. As the cutter enters the corner-radius areas, the X cutting limits are automatically reduced to follow the programmed pocket geometry.
The programmed stepover is used as the maximum value and automatically equalized across the available pocket width for a consistent roughing pattern.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
🎯 ROUGHING + FINISHING
A programmable wall allowance is left during roughing. After each roughing level, the cycle automatically machines the complete finished rectangular profile including all four internal corner radii.
One cycle handles:
✅ Helical entry
✅ Raster roughing
✅ Corner-radius calculations
✅ Wall stock
✅ Complete finishing contour
✅ Multiple depth levels
