MACS Violations in High-Tier Matrices
When generating deep master key hierarchies, mathematical bitting combinations can generate adjacent cuts exceeding MACS (e.g. depth 0 next to depth 8).
Software Recovery & Ramp Interpolation
- Automated Flagging: CNC key software automatically flags any cut step > 5.
- Ramp Angle Interpolation: The software recalculates the transition angle to a smooth 45° lead-in ramp, preventing key binding while maintaining shear line integrity.
Frequently Asked Engineering & Selection Questions
Q1: What is MACS violation recovery in key cutting?
Software that detects overly steep cut steps between adjacent pins and smooths the transition angle to ensure smooth key insertion.
