Measureing? Challenges

• When measuring the wall thickness of small-sized sheet metal square tubing, traditional measuring tools often fail to meet the required precision, and human errors easily occur.
• Traditional methods only provide static data and are unable to monitor the changes of the fitting sizes in real-time or detect quality issues during the production process.

Recommended Solution

1） Measurement Principle

When measuring square tubing, the operator needs to hold the portable arm and touch the probe on the surface of the measured target. By rotating and moving the elbow, the arm is able to collect coordinate data from different positions on the tubing. Then, the data will be transmitted to the control system and processed and analyzed by the software. Finally we get the required dimensions, shapes, and positions of the tubing.

2） Measurement Steps

• Establish the Coordinate System

① Compare the workpiece with the drawings. Analyze the drawing requirements and relations between each dimension, and identify the features on the workpiece. Use the measuring arm to detect the relevant feature elements.

② Import the CAD model. After importing the CAD model, the PMT engineer will delete unnecessary components (such as cylinders, connecting blocks, valve islands, brackets, screws, etc.) according to the requirements of the CAD model, and retain the modules that need to be inspected.

③ Establish the coordinate system (usually using methods such as the center point of the plane axis, iteration, etc.). Align the measured data with the nominal data to establish the positional relationship between the measuring arm and the workpiece. This will facilitate the next steps.

• Data Acquisition

Contact measurement with the portable measuring arm: The engineer will collect data by touching the surface of the workpiece with the ball probe of the arm and use the least squares method to best-fit the measured data parameters.

• Data Analysis

Based on the technical requirements, we can analyze the position of holes and surfaces. In the measurement system, the shape deviations, position and other parameters of the measured object can be evaluated, and the key dimensions can be marked.

• Report Generation

Generate a report based on the measurement results. The report should include basic information about the measured object, parameters, results, error analysis, and other relevant content.

• Feedback of Results

Send the measurement results to relevant departments so the company can facilitate subsequent production, processing, and quality control activities.

• Batch Inspection

Since sheet metal components are often mass-produced, it is common to conduct random sampling or batch inspection of the same product. In such cases, the creation of new workpiece command in the software can be used for repeated inspections, with no need for data editing or processing, greatly improving measurement efficiency.

Advantages of the Portable Measuring Arm in Pipe Fitting Inspection

① High Precision

The PMT portable arm employs advanced angle encoder technology, enabling high-precision measurements that meet the requirements of most industrial production and quality inspection processes.

② High Efficiency

Compared to traditional methods, the PMT measuring arm is easy to install and calibrate. Operators can quickly learn how to use the machine, an process and analyze the data through the software, reducing the workload associated with manual calculations and data handling, thereby increasing work efficiency.

③ Strong Flexibility

The PMT portable measuring arm can rotate and move flexibly, adapting to the measurement needs of square tubing of various shapes and sizes. It can also be used in complex environments.

Other Applications

In industries such as mechanical manufacturing, automotive manufacturing, and aerospace, square tubing is widely used in the production of various structural components. For large square tubing structures, such as steel structures in construction or bridge structures, the PMT measuring arm is able to perform rapid on-site inspection to ensure construction quality control.

During the research and development of square tubing, the PMT portable arm can provide precise measurements of samples to optimize the design process. It can also compare different schemes and select the optimal design for customers.

Conclusion

The PMT portable measuring arm is the ideal tool for measuring sheet metal square tubing. With its high precision, high efficiency, and strong adaptability, it meets the high demands of industrial manufacturing, provides reliable quality assurance, and plays an important role in the research and development stage, showing great value across different industries.

Price war has become the norm since the rapid development of the market will inevitably bring fierce competition. However, the market has proved that car companies have been raising their competitiveness, and the trend has shifted from low-priced competition to applications of cutting-edge technologies, exceptional performance of products, and branding development. This will help reshape the industry.

3D measurement technology has been playing an increasingly important role in modern manufacturing. It can provide high-precision measurements for different sizes and shapes, which is of great significance for improving product quality and production efficiency. As an advanced 3D geometric measurement system, PMT ALPHA has a built-in counterbalance system which is specially designed for on-site inspection. The structure of the equipment is simple and balanced, thanks to its perfect equal arm length design, which delivers an outstanding arm-operating experience. PMT portable arm is compatible with many measurement software and widely used in manufacturing industries as follows.

Reverse Engineering

In scanning clay sculptures or similar kinds, the Alpha M ScanArm can quickly model with its collected data without pasting marking points, which greatly shortens the design cycle and thus improves efficiency. Here is an example from a car manufacturer who used reverse engineering to do 3D modeling of a prototype car during the process of creating a new model. It all only took two weeks, saving about 40 percent of the time compared with traditional methods.

Molds and Production Tools Inspection

Use ALPHA Arm to do regular inspection of molds and production tools, and to analyze the wear condition so repairs or replacement could be made. For example, the customer used the PMT Alpha arm on their auto parts production line to inspect the mold on a regular basis. They detected and fixed a slight wear problem in time, helping prevent production delays and cost increases caused by mold damage.

CAD Model Comparison

Using ALPHA Arm to measure 3D coordinates will help ensure the accuracy of auto parts. We can see deviations between the actual workpiece and the CAD model by comparing the measured data with the nominal data. For example, in a process of quality control of key components, the operator used the ALPHA arm to detect dimensional deviations in a batch of components, and feedback was immediately sent to the production department. It effectively helped prevent the customer from producing batches of substandard products.

Tool Alignment

We can make adjustments to the assembly position according to the obtained accurate data of the auto parts so as to make sure the accuracy and quality of the whole process. For example, on the assembly line of a high-end model, the application of the PMT ALPHA arm has improved the assembly accuracy by 20 percent, significantly enhancing the quality of the vehicle and customer satisfaction.
