JEC Europe 2013 - Automation solutions from BCT substantially reduce machining times while at the same time improving the quality of the repair preparations.

Manual repair and reworking of composite components are time-consuming and work-intensive. This is especially true of scarfing performed as preparation for patch repair. With geometrically adaptive 5-axis milling, composite components of different shapes can be scarfed fully automatically. Automation solutions from BCT substantially reduce machining times while at the same time improving the quality of the repair preparations.

With the OpenARMS-CompR (Composite Repair and Reworking) software solution, scarfing is performed automatically. The program comes with a convenient user environment for easy setup.

Patch patterns and scarfed areas of all kinds can be milled. The geometry of the scarfed area is given by the master milling program; for example, 2.5-D pocket milling with 3 axes.

CompR generates scarfed areas on "unknown" component geometries. The line scanner first captures the topology of the damaged area and then scans the 3D geometry with a high degree of accuracy.

A 3D surface model reproducing the actual geometry of the damaged area is generated from the scanned points. The master milling program is then wrapped onto to the 3D surface geometry. The geometrically adapted milling programs have 5 axes and run parallel to the contours of the actual geometry of the damaged area.

5-axis milling of the scarfed area is then performed on the mobile or stationary NC machine. A wide variety of milling strategies and cutting tool geometries can be used here.
