The system is fully automatic. The machine operator controls and monitors the complete process via the 'CADmatic 4 PROFESSIONAL' operating software on the control panel of the panel-sizing saw.
- First, the machine operator positions a test panel in the saw. The main saw and the scoring saw each cut a groove in this panel, fully automatically. The saw carriage is then re-positioned and travels along the grooves guided by the camera, pausing at various pre-defined points to take pictures.
- To ensure optimum measuring results, the camera has LED lighting with various colours to illuminate the panel. Based on intelligent software algorithms, it then independently selects the appropriate lighting colour – depending on the panel colour – and also the correct exposure time.
- Once the grooves have been captured by the camera, they are measured with the image processing software. The machine controller then regulates the alignment of the scoring saw blade to the main saw blade. The new magnetic linear measuring systems are installed on the scoring saw. These are non-contact, non-wear and dirt-resistant. The machine operator sees the result displayed in real time via the CADmatic machine controller software on the 19-inch touch screen display.
- A control cut is then completed – also fully automatically – in which the alignment is checked for accuracy.
The machine operator does not normally have to check the new scoring saw adjustment. If required, he can of course carry out a visual check after a test cut. Normally, it is also completely unnecessary to repeat the adjustment process.
The entire process takes about one minute, but it depends on the degree of misalignment and on the level of precision required – however, it is always faster, simpler and easier to repeat than a manual adjustment.
If required, manual operation is also possible – with advantages here too
Of course, the new system allows manual adjustment as before. And here too, there are noticeable improvements: the installed measuring system is considerably more precise. You can now specify the saw blade travel in resolution increments of just 100ths of a millimetre – by entering numbers via the mouse or via the touch screen. This is displayed via a cross-hair display in the 'CADmatic 4 PROFESSIONAL' operating software.
The Novelty Symposium is a joint initiative of the 'Holz-Zentralblatt' journal, Rosenheim University of Applied Sciences and Schuler Business Solutions AG and was staged this year for the 16th time at the LIGNA Fair on 16th May. Specialists from the woodworking sector and furniture industries present the most important innovations of the fair and new trends from the fields of furniture manufacture and construction elements. They present exhibits that represent an innovation not only for the makers, but in the industry itself and which have been on the market for a maximum of two years, in other words, products that were not shown at the last LIGNA.
The innovations in one of the three categories, "machine-based production", were presented this year by
Prof. Dr.-Ing. Frieder Scholz from Rosenheim University of Applied Sciences.
At the end of the Novelty Symposium, the participants gave their assessments of the products. The camera-controlled scoring saw adjustment was a particular hit among those present and took first place in the category "machine-based production".
