Radian Laser Tracker Helps Poten Heavy Industry Efficient measurement of large machined parts

This is simply too convenient! With such a large workpiece, simply measuring and collecting data from some points can achieve comparative analysis of flatness and parallelism between two planes, "said Li Gong from the quality inspection department of Poten Heavy Industry." The detection efficiency has made a qualitative leap compared to before

Our customers
Poten Heavy Industry, located in the Jiangsu and Zhejiang regions of China, mainly engages in the processing of large and oversized structural components. It has mature technology and exquisite craftsmanship, strict product quality control, and is widely praised in the industry.

The products processed by it mainly serve industries such as mines, ships, railways, molds, metallurgy, etc., and are widely used throughout the country; High quality products have also gained international recognition, and their products are also exported to countries such as Germany, Russia, Japan, Mexico, etc.

Measurement requirements

Based on the business field of Poten Heavy Industry, the required measurement targets are large workpieces ranging from several meters to tens of meters. Faced with increasingly high customer demands, the inspection requirements for workpieces have become increasingly strict. For large workpieces ranging from several meters to tens of meters, the measurement accuracy requirement of 0.2mm-0.3mm is already the norm. For some components used in high-order production, the accuracy requirement can reach 0.1mm or even 0.05mm.

It is very difficult for traditional measurement methods to achieve such high-precision detection on such a large scale. In addition to measuring tools that cannot reach the scale range, objective factors such as personnel operation level and on-site measurement environment can also have a significant impact on the final measurement accuracy.

API Solution

The Radian series laser tracker from API brand is an excellent solution for large-scale and high-precision measurement. The Radian laser tracker has a measurement range of 160 meters (radius of 80 meters) and has a micrometer level measurement accuracy. The design is compact and compact, with a host weight of only about 10 kilograms. It can be placed around the workpiece to be measured according to on-site conditions to achieve measurement.

During measurement, the operator holds a high-precision laser tracker ball (SMR) with a built-in prism, and the laser emitted by the Radian tracker will shoot towards the center of the SMR ball and lock the tracking in real-time; The operator only needs to touch the tested part on the workpiece with SMR, and Radian will accurately measure the three-dimensional position data of the tested point at a collection rate of 1000Hz (1000 points/second), and feedback it to the Measurement Software for recording and analysis; After the data collection of all the points to be measured is completed, the operator can use the spatial data of these points in the software to construct corresponding lines, surfaces, and bodies, thus implementing the analysis of geometric tolerances between various components or positions to be measured.

Measurement software can quickly generate inspection reports in various forms, including tables, bar charts, pie charts, arrows, color difference charts, etc., making measurement results clear at a glance and providing reliable improvement data for production.

Customer on-site application examples

At the production site of Poten Heavy Industry, engineers need to measure and analyze the flatness and parallelism of the machining surfaces ① and ② (please refer to Figure 2).

Firstly, the operator places the Radian laser tracker in a suitable position in front of the workpiece, connects the Radian laser tracker to a laptop, and turns it on. This completes the preparation work before measurement and starts measurement at any time.

In the second step, the operator uses a tracker target ball (SMR) to take measurements on two planes: ① and ②. After the target ball touches the position to be measured, the laser tracker immediately measures and collects the three-dimensional data of the spatial point at a collection rate of 1000 points/second, and sends it to the measurement software on the laptop for storage.

Step 3: After the three-dimensional data collection of all the positions to be measured is completed, the software can use the data collected from points on planes ① and ② to fit the standard plane, and achieve distance analysis from each measurement point to the standard plane, thereby obtaining flatness analysis data; After constructing two planes, parallelism comparison can also be achieved.

In three simple steps, the required measurement content has been completed, ensuring high measurement accuracy while significantly improving detection efficiency, providing escort for production!
