APDIS in Automotive
A paradigm shift in shop floor inspection
Utilizing non-contact laser-based technology, the APDIS Laser Radar can directly measure automotive features without the need for surface preparation or adapters making it ideal for fully automated measurements directly in the production line.
APDIS’s long range and large standoff allows for measurements in all areas of the car body in absolute coordinates to HA CMM accuracy. Precision control of the beam creates optimized scan paths for features, keeping data sets small and measurement speeds fast.
The new APDIS MV430E ‘Enhanced’ model delivers the fastest ever Laser Radar, further increasing measurement throughput and productivity for automotive applications.
For automotive inspection, the APDIS Laser Radar offers the ideal capabilities to meet the need for flexible and absolute measurements directly on the shop floor. For automotive manufacturers this results in:
Faster tuning of new production line or vehicle model changes
Improved process control
Future proof data
Benefits & features
Absolute accuracy on the shop floor
Using the APDIS system within a fully automated robotic measurement solution introduces an innovative approach to body-in-white (BIW) inspection.
- HA CMM accuracy
- Absolute coordinates
- Direct comparison to CAD
- No off-line correlation
CMM quality data without adapters
Features such as holes, slots, pins, studs, surfaces and edges can be quickly inspected using the APDIS Laser Radar directly without the need for special feature adapters. The measurement accuracy and repeatability of the Laser Radar is comparable to measurements taken with a traditional horizontal arm touch probe, whilst being many times faster
- Fast setup
- Direct feature measurements
- 6 x faster than traditional monolithic devices
Robot independent accuracy with simplified programming
The robot positions the Laser Radar to provide line of sight to the required features; the Laser Radar then automatically realigns to the part by measuring tooling balls on the fixture. As such all measurements are collected in the vehicle coordinate system and feature accuracy is independent of the robots ability to accurately locate the Laser Radar.
- Absolute measurements
- Independent of robot accuracy
- Minimal robot positioning
- Large standoff for part safety
- Long standoff for feature accessibility
What industry research company “Frost & Sullivan” reports on Quality 4.0 in body in white inspection
“As Body-in-White inspection moves in the direction of Quality 4.0, it will become a fully automated, non-contact, absolute measurement process integrated into the production line. Traditional inspection approaches, such as horizontal arm CMMs, are being replaced by newer, automated approaches like Laser Radar systems.”

Boost inspection productivity in the metrology room
Using APDIS in the metrology room as a replacement for traditional CMMs, the off-line facility ceases to be a bottleneck due to faster measurements allowing quicker problem investigation. APDIS can be used for a range of parts sizes from component inspection to full chassis and BiW depending on the configuration, offering many benefits:
- Increased throughput with 8 x faster measurements than traditional column CMM
- Fast setup with non-contact measurements and no feature adapters
- Access difficult to reach areas with long range measurement
- CMM comparable accuracy in a fraction of the time
- Multiple stations served by single Laser Radar
- Instant results with small data sets
- Increase efficiency by only measuring what is needed when performing limited specific investigations
Innovating production line inspections
The APDIS MV330E provides the fastest feature measurements of any Laser Radar to date allowing inspection of critical features in the takt time of the line or a sampling strategy to cover more features over a set of car bodies for true process control. By automatically removing a car body from the line, detailed inspection is possible on vastly more components than previously possible. Single or dual APDIS bypass installations allow for the highest inspection productivity to CMM accuracies. After inspection the body is automatically re-inserted into the production line for seamless integration.
