to take a full image of a part and provide dimensional and characteristic measurements, such as concentricity. Manufacturers can place a bottle on a turntable and use a camera to scan the shadow created by placing the object in front of the light source. They can then compare the results with the original drawing interchange format (DXF) file to see the deviation. Engineers can also automate measurement
by using the RPS measuring arm, which users can equip with a probe or a laser for non- contact measurements. Once manufacturers have produced a line of bottles, they can move a laser scanner across them to assess the different areas. They can then use this data to generate a point cloud, align it with a perfect CAD model and produce a deviation map. This will show the high and low areas, and how they differ from the design.
REPORTING AND EVALUATION Automation enables manufacturers to evaluate and communicate measurement data with stakeholders. Traditionally, such information was presented in separate spreadsheets, often confined to out-of-sight filing cabinets. However, using systems like the Jenoptik Opticline and RPS arm, manufacturers can take this data and feed it into SPC software like Prolink to create complete, downloadable reports.
Integrating sophisticated software can elevate inspection reporting significantly. These platforms can display measurement results using a graphical user interface so that manufacturers can identify
trends and respond. For example, if the same area on several bottles moves towards the upper limit, manufacturers can alter the production process before this leads to a defective product line. As more packaging companies pledge their commitment to sustainability, glass bottles will only grow in popularity, and optimising inspection processes is critical. Automating inspection helps manufacturers prevent defects and ensure high quality products while minimising waste and rework. Installing the right measurement systems and training staff to use them is essential and working with a dedicated metrology partner is the first step.
