Industrial Applications of PMT GAMMA Measuring Arm

Automotive Inspection Solutions

The PMT GAMMA E portable measuring arm stands out for its exceptional cost-effectiveness, providing high precision measurement results while reducing overall costs.

To meet the complex demands of sheet metal inspection, the lightweight GAMMA E is compatible with a variety of PMT’s self-developed accessories, including electric clamping vacuum plate, folding adjustable tripod, and circular disc integrated magnetic mount, offering easier and faster installation.

During inspection, engineers mount the hardware on the fixture base plate following a predefined measurement path and specified conditions, then establish alignment using reference holes to analyze the workpiece. To overcome the challenges of measuring multi-layer sheet metal, the “Inverted Normal Orientation Inspection Method” automatically identifies clamping errors and accurately detects deformation deviations, improving the capability of detecting industrial design issues by more than 50%.

In the automotive industry, inspecting car dashboard assembly requires high accuracy, especially for narrow location holes and precise surface alignment. To meet these demands, the PMT GAMMA M 7-axis 3.5m ScanArm (a portable measuring arm equipped with a blue light scanner) was applied in a factory to enhance the quality control processes for interior trims through innovative technology.

By simply adjusting the position of the probe, the next-generation GAMMA and laser scanner enables 90-degree elevated scanning, effectively capturing the complex surfaces of the instrument panel top. This capability allows it to precisely address inspection requirements in the critical transition zone between the instrument panel and the windshield. In a vehicle project, this technology simplified a three-step clamping process into a single operation, achieving a data completeness rate of up to 99%.

The GAMMA portable cmm’s rapid switch between contact measurement and non-contact scanning enables accurate verification of hole positions and analysis of assembly gaps between trims and the base structure, delivering a flexible, efficient, and reliable inspection solution that meets the demands of smart automotive manufacturing.

Engineering Machinery Measurement Systems

Equipped with a newly designed double handle featuring a force-isolation design, the PMT GAMMA measuring arm can be quickly mounted onto complex tubing inspection worktable by a single person, boosting installation speed by over 70%. This setup enables full-process precision verification of initial bending parameters in bent tube products, significantly enhancing accuracy and productivity.

During the measurement process, the operator uses a smart probe to perform contact sampling on the workpiece surface, accurately capturing key parameters such as pipe diameter and bending angle. The system can generate comparison charts of nominal, measured, and deviation values, along with structured inspection reports, providing clear visual data to optimize whole process.

With its external decoupling and internal balancing system, the portable cmm maintains smooth and stable operation even in a tight space, such as narrow pipe interfaces or vertical risers, which overcomes a key bottleneck of inspecting large or irregularly shaped parts in the engineering machinery industry.

The positional tolerance of the transmission mechanism from the wheel axle to the engine mounting point has directly affected power transmission capability, overall operational stability, and the service life of critical components in a plowing machine.

Designed for on-site measurement, the PMT GAMMA measuring arm features a temperature monitor that provides real-time compensation every five minutes and records temperature changes over time.

When abnormal fluctuations occur in the tolerance data of the transmission mechanism, engineers can reference the historical temperature records to quickly identify the issue using tilt diagnosis, which also monitors the cmm’s installation status in real time.

The intelligent prompts of measuring arm guide engineers in the proper use of the device and help adjust equipment fastening methods, thereby reducing operational errors. In one inspection case at a leading enterprise, the detection rate for plowing machines increased by more than 50%.

Quality Control in Shipbuilding

For core defect issues such as bearing hole wear and sealing surface deformation in motor covers for ship parts, the GAMMA measuring arm can be flexibly integrated with various popular 3D measurement software. It enables simultaneous inspection of circles, diameters, and flatness, accurately capturing critical dimensions. The measurement results are then fed back to engineers, allowing for the generation of processing drawings and establishing a full workflow of “measurement – modeling – repair.”

Computer Aided Measuring 3D (CAM3) is a powerful measurement software developed by PMT, featuring fully independent core algorithms and certification from PTB – an internationally recognized authority in metrology, is known for its strict global standards for measurement reliability and nanometer-level accuracy test. When paired with the PMT portable measuring arm, CAM3 ensures encrypted data transmission and secure storage, safeguarding critical inspection data in the marine machinery industry.

In UK, the PMT GAMMA P equipped with a blue light scanner efficiently completed the full-size scanning of a highly reflective metal demo part. With a laser point cloud acquisition rate of 1.2 million pts/sec and an extended scanning distance of 220 mm, combined with its built-in intelligent ventilation system, the machine delivers outstanding consistency, easily meeting the demands of even the most challenging industrial scenarios both at home and abroad.

The force-isolation design, inspired by the “breaking the whole into parts” principle, decouples the handgrip from the scanning head to improve operability. Additionally, the device is over 50% lighter than the previous generation.
