Delcam’s combination of a dual-column CMM and PowerINSPECT enables reduced inspection times because of the ability to simultaneously measure different features on larger parts.

An example of a common application is an automotive body-in-white inspection, wher the evaluation of a large, complex assembly requires intricate measurements on each side and an assessment of the structure as a whole.

This new module has the ability to measure parts on this type of device – in a single coordinate system – without repositioning.

The dual-column mode works in a similar manner to the single-column CNC version of PowerINSPECT. Models are loaded in the same way and inspection items are created using the same methods.

The main difference is an additional programming operation is needed to distribute the various items to be inspected between the two columns. Additions to the offline-programming and program-running capabilities provide easy tools for moving inspection items between the two columns to balance the inspection time needed for each one.

The user can switch columns in much the same way that they switch probes or tools. To ensure safe operation of the CMM, the collision predictor within PowerINSPECT checks for possible collisions between columns by calculating their moves as the inspection proceeds and comparing their future positions in space and time.

If overlap is detected, the inspection is stopped and a warning displayed. Because of factors like speed, this is the only reliable way to prevent collisions between columns.

The dual-column version of PowerINSPECT offers the same comprehensive range of inspection routines for simple measurements and for analyzing complex 3D surfaces. The resulting reports present detailed information in an easy-to-read format, that can be understood by all engineers not just inspection specialists.
