Penjelasan Siklus Bor:

• G81: Siklus bor standar (Spot Drill)
• G83: Siklus bor peck (Deep Hole Drilling) dengan parameter Q untuk peck depth
• G84: Siklus tap (Tapping)
• G85: Siklus bor/ream (Boring/Reaming)
• Menggunakan G98 (Return to initial level) dan G99 (Return to R-level)
• Tool length compensation G43 H... untuk setiap tool
• Cutter compensation G41/G40 untuk profiling
