Computerized Measuring Systems Popular Systems Manufacturer Name Car-O-Liner - Car-O-Tronic Vision Chief - Velocity, Vector, LaserLock Blackhawk/Snap-On - Shark Style Robotic Laser Sonar The different names represent newer software versions and upgrades There are many other manufacturers that have similar styles of systems Robotic – Electro-Mechanical Communication to computer via Bluetooth Laser scanner emits 2 laser beams to triangulate position of targets; then fed to computer software Shark probes emit an ultrasonic sound that is received by microphones in the beam to locate position Measuring Systems • Detect Misalignment • Monitor Repair Process • Verify the Repair The main focus of the technician is the amount of deviation from factory specification Unibody tolerance – 3mm or less BOF tolerance - 5mm or less Car 0 Liner sheet shows Right and Left specs for each side Points that are measured show deviation from factory specification Display allows quick analysis of diamond (Length) or twist (Ht) and direction of other areas of damage Point R5 has: 9mm of Mash 15mm of inward Sidesway 5mm of Sag/Kickup L W H L W H In contrast, the Velocity sheet is quite a bit different Comparitive measurements have no factory spec to show a deviation from Quick check for Twist or Sag Height R/L Notice “Front” marking Even # Targets on Right Odd # Targets on Left Arrows indicate R/L directionWidth of movement “Sidesway check” Right and Left Dimensions are grouped together Length R/L and there is no side view Quick check for Diamond or Mash The Shark system’s measurements are not on a graphic spec sheet Control points are referenced by letters that correspond to the list of measurements Control Points Left or Right Measurements Points B and A are the center section B is always the rear torque box area or “Zero” line Report of Damage Conditions Using Points G as an example Box shows location and size of hole/bolt L W H Specification Actual Measurement Deviation G (L)Deviation is 2mm short - is Mash The line the first place the Arrows point “away or toward” 11mm away look from centerline – Sidesway technician would to determine if Zero and Datum Lines 1 mm too high – Sag or Kickup the vehicle is out of spec Minus symbol shows Point is closer to Centerline “0” would be perfect or match spec
