How is Optical Metrology Benefitting the Metalworking Industry?

The prime objective of the metalworking industry is to produce parts that meet their customers' specifications and are within the required tolerances.

Fremont, CA: Production of castings is a long process in which each stage plays a vital role in the creation of final parts that meets the customers’ requirements. To do so, raw castings are produced, then, machined, and validated. Therefore, the metalworking industry’s contribution to the manufacturing process is indispensable and essential. It must produce raw castings that have enough material for the machining process so that the final parts are of inspection standards. It must secure this while minimizing inspection time and the cost of production associated with rejected parts.


Production of parts includes machining raw castings. In order to optimize machining and ensure good quality, these surfaces must have enough material; otherwise, the mechanical contacts can be defective, and tolerances might not be met. Thus, the manufacturing industry understands the benefits of inspecting castings before and after machining. The primary objective is to produce parts that meet the required tolerances. Additionally, some manufacturers go as far as investigating the mold to produce better raw castings. The shipping of non-compliant parts to the clients in large quantities can lead to financial and legal issues. The clients demand quality inspection reports on each part to keep themselves safe. This is where optical metrology can be of great help to the metalworking industry. Top 10 Metal Working Solution Companies - 2020


Parts of Better Quality

Keeping in mind the part quality, and not having a nominal mold built according to the CAD file, will fast-pace the production time. This way, unpredictable phenomena will be taken into account in the manufacturing process.

Shortened Inspection Time

With a recovery rate of 1/2 million points per second, 100 percent of the surfaces can be inspected within a few seconds. Adding to that, the part no longer has to be shifted to the metrology lab for inspection. Therefore, checks made with portable 3D scanners mean being able to inspect more castings faster and with more information while freeing up CMM time, which can be used for more critical and valuable tasks like final inspections.

Reduced Production Costs

By inspecting castings before and after machining with a portable 3D scanner, the metalworking industry can instantly identify those that do not have enough material, limiting the cost associated with their production. Therefore, these castings can be redirected and reworked before investing in them further.
