Flatness control

July 2016

German levelling and deburring specialist, ARKU Maschinenbau GmbH, premiered its FlatJack®– a new process for monitoring the flatness of sheet metal parts – in May this year. FlatJack® is designed, it told ISMR, to ‘check the flatness of punched, laser-cut and flame-cut parts rapidly, precisely and with minimum work before and after levelling’.

“Level and low-stress panels are essential for automated sheet metal processing. Up until now, the flatness of sheet metal parts was typically measured using spirit levels, straight edges and feeler gauges. These may soon be obsolete because they require time-consuming handling and experience to use properly. Heavy flame-cut parts require extensive positioning to obtain precise measurements. With the FlatJack®, we have developed a control process which can be integrated directly onto the inlet rollers of the FlatMaster® precision leveller. This minimizes the cycle time and costs through reduced non-productive times in the levelling process,” explained ARKU.

The surface of the sheet metal part is tested by the laser integrated into the inlet rollers, regardless of orientation and position. The measurement equipment traverses the part and measures its flatness. The results are automatically transferred to the FlatMaster® control system and can be accessed at any time. This ensures complete documentation and reproducibility. The measurement process fulfils the requirements of the international standard, DIN EN ISO 12781.

"When developing the FlatJack® flatness check, we focused on making the system fully automatic and user-independent. Automation reduces the training and personnel costs. At the same time, our customers can use their personal resources more efficiently by saving time when measuring large parts. With the FlatJack®, we are making an important contribution toward Industry 4.0,” concluded ARKU.
