China’s auto exports and annual sales take the lead in the world amid the rapid development of new energy vehicles. The nation is moving steadily toward a new phase of growth for its auto industry featuring intelligence, sustainability and innovation.
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.
