; Classification: IMPERIAL RESTRICTED
; Part: Security Master Key - Type MK-II
; Machine: KDY Precision CNC Mill Series 500
; Date: Imperial Standard 67.4.12
; Operator: Chief Manufacturing Officer Rahn
; =====================================================

; --- MACHINING SPECIFICATIONS ---
; This file follows Imperial Standard KDY-7734 for
; security key manufacturing. All measurements in mm.

; PIN CONFIGURATION (Imperial Standard Layout):
; The MK-II key uses a 5-pin tumbler system.
; Pin positions are fixed at the following X offsets:
;   Pin 1: X = 12.0 mm
;   Pin 2: X = 20.0 mm
;   Pin 3: X = 28.0 mm
;   Pin 4: X = 36.0 mm
;   Pin 5: X = 44.0 mm
; All cuts are made at blade centerline Y = 5.0 mm

; BITTING DEPTH STANDARD (KDY-7734 Section 4.2):
; The bitting value for each pin equals the absolute
; Z-depth in millimeters. For example:
;   Z = -3.0 mm corresponds to bitting value 3
;   Z = -5.0 mm corresponds to bitting value 5
; Bitting sequence is read Pin 1 through Pin 5.
