Cutter Compensation Direction

During CNC planning and execution, Cutter Compensation Direction denotes: Selection of left or right compensation direction. When this chain is wrong, cutting can be wrong even if every single number looks valid. A clear standard around this topic usually shortens prove-out time. Cross-checking machine and bench measurements helps catch systematic bias early.

Where It Shows Up

Treat this as part of an integrated process chain rather than a standalone parameter. That approach reduces trial-and-error and speeds up reliable release.

Execution Guidelines

• Simulate with the same active coordinate chain used at the control.
• Separate machine zero, work offsets, and local shifts in setup sheets.
• Validate transform order whenever rotation, scaling, or mirroring is used.

What to Watch During Production

• Mirror or rotation direction mismatch
• Probe values drifting after reclamp
• Uniform part shift across all features

Frequent Issues

Offset stacking errors usually come from hidden local shifts or stale pages. Coordinate mistakes often survive simulation when setup assumptions differ from reality.

Verification Checklist

• Store a baseline offset snapshot for quick comparison.
• Confirm active work coordinate and local shift state before start.
• Verify probe readings against setup targets on sentinel datums.
