The components made of composite and hybrid materials such as composite- titanium laminates are increasing in the aerospace sector. Among the different machining processes, drilling is especially relevant due to the high number of operations that have to be performed and the consequences of the damages that can be originated in the workpiece. Thus, it is essential to understand the particularities of these new materials and advance in the development of new drilling techniques. The objective of this article it to provide a comprehensive review of the key aspects that must be considered when drilling composites and composite-titanium laminates. Emphasis is given to the possible damages in the material surface and to the wear mechanisms of the cutting tool. Moreover, several recommended practices are presented and three advanced techniques are described: orbital drilling, peck drilling and vibration-assisted drilling. Keywords: Drilling, CFRP, stacks, wear, orbital drilling, vibration-assisted drilling

Burnishing increases the surface hardness through the cold working process and compressive forces. It increases metal’s resistance to fatigue and failure at stress points. These benefits make burnishing ideal for sealing or bearing surfaces, various seats, areas that require pre-stressing, tight diameter tolerances or just areas that require good surface finishes.

Fast cycle times mean that burnishing projects are measured in seconds, not minutes. Speed is coupled with accuracy, as ID burnishing tools produce accurate sizing in 0.0001-in. increments. Roller burnishing results in a 25% size improvement in steel and up to a 50% size improvement in high ductility materials.

By improving surface irregularities and tool marks, these easy-to-use tools also eliminate secondary operations, such as grinding, honing, and polishing, thereby cutting project costs and lead times.

In addition to custom tooling, Monaghan Tooling Group offers standard tooling for ID multi-roller burnishing, OD carbide roll burnishing, ID/OD carbide roll burnishing, and diamond burnishing. All tooling styles are easy to operate and require limited training. They are easy to maintain and repair, and common repair parts are available from a fully stocked inventory.

MONAGHAN TOOLING GROUP is offering a full line-up of Elliott Tool Technology burnishing tools, which produce a 4 to 8 Ra surface finish in one pass, thus eliminating secondary machining operations and the requisite set-up time and costs. With tooling to burnish ID, OD, ID/OD and flat surfaces, Monaghan offers the tools to handle virtually any burnishing project.
