PMD | Highest Flexibility in Body Construction

The components in the car body construction must be machined to an accuracy of tenths of a millimeter in order to meet quality requirements. To check the dimensions, the sheets are measured several times using optical or tactile methods. To do this, they must first be clamped in a fixture that holds them exactly in the installation position. At present, an individual measuring fixture is provided for this purpose for each individual sheet metal component. The PMD, on the other hand, is able to set itself up independently for a new measuring task in less than 2 minutes. To do this, it uses support points that can be positioned very precisely via NC axes. Instead of a large number of individual measuring fixtures, only one flexible measuring fixture is required - the PMD.

The PMD has been developed in cooperation with the Fraunhofer Institute for Machine Tools and Forming Technology.

Advantages

• Reduction of costs for fixture planning and procurement
• Less space required
• Less planning effort
• Flexible workspace
• Higher productivity in QA due to shorter setup times and high component flexibility
• Simple operation
• Configuration without PLC knowledge
• Applicable for 95% of all customer parts
• More frequent measurement without effort allows error trends to be identified at an early stage
• High repeatability
