Customer background
A heavy industry enterprise in East China, whose main business is welding and processing large-scale high-precision frame parts.
Measure the demand
1. The hole position of the welding plate directly above is detected. The parts are about 40 meters long and 15 meters high;
2. Detection of the position and aperture size of the hole on the side;
3. The area of the reference plane is large, and the overall flatness of the plane and the height difference of the plane cannot be evaluated;
4. The temperature influence is difficult to control the position accuracy of the parts;
5. Online testing to ensure the size control during processing.

API solution
Using API Radian Core laser tracker measurement system, the configuration scheme includes:
- High-precision static measurement: based on Radian Core laser tracker, micron-level accuracy measurement is realized;
- Temperature compensation module: built-in sensor automatically corrects the impact of environmental temperature and humidity;
- Portable design: equipment weight <11kg, quickly deployed in the measurement workstation and convenient for transfer;
- Universal accessories can quickly measure the hole position and improve the overall measurement efficiency.

Measurement and implementation
When measuring, the Radian Core tracker will shoot the laser to the target ball with the built-in prism and track it. After the target ball fits the position to be tested, the tracker can manually or automatically measure and collect spatial data on the target position. After data collection, it will be transmitted synchronously to the laptop terminal. In the measurement software, it is used for follow-up analysis.

Measurement results
1. Through the measurement of Polyworks software and API laser tracker, the accuracy required for all welding plate holes and the accuracy of the plane can be obtained;
2. Automated reporting: Through the rapid report generation of Polyworks software, the measurement needs of end customers can be obtained;
3. The wireless transmission function of the tracker and the reasonable application of accessories have greatly improved the work efficiency of equipment transfer.
Note: In addition to the use of Polyworks measurement software in this case, the API laser tracker can also be compatible with most measurement software on the market (such as SA, Metrolog, Verisurf, etc.); in addition, API also independently developed M according to the characteristics of the instrument and combined with front-line applications. easurePro measurement software can be applied to the compatibility of API full-series measurement equipment and integrated data analysis.
Customer comments
"The measurement and scheme of API has allowed us to find a way to measure this large workpiece, that is, to measure this large workpiece and control the size of the workpiece during the processing process. We are more confident in taking over the follow-up order."

More expansion
In addition to the Radian Core model laser tracker used in this case, the full series of API laser tracker products also include:
- Radian Pro, integrated IFM/ADM dual laser, measurement data can be traced;
- Radian Plus realizes the compatibility and adaptation of the probe and six-dimensional accessories on the basis of Radian Core;
- iLT/iLTx, on the basis of fully wireless measurement, further reduces the overall size of the laser tracker by 50% (compared with the Radian series), and the weight of the whole machine is only 4.9Kg, giving full play to the portable properties, fully satisfying and suitable for going out, outdoors, narrow spaces, Multi-machine integration and other application environments.
