“…Robinson [3] systematically gave several practical tips and useful principles gathered from technicians and engineers on the template design considerations. Jayaweera [4] described the development and test of flexible tooling to provide clamping and support for drilling wing box ribs posts within a restricted environment. Wiemann [5] introduced a flexible template for drill units which can be pinned into piloted datum holes, allowing the jig to find the form of the work piece.…”

Drilling jigs are used frequently to provide precise location of a hole pattern for mating parts and assemblies in aircraft fabricating process for their accuracy and simplicity. Due to the different product batches and manufacturing process, the components which will be assembled together possess distinct geometry properties or reserve different edge margins, thus the location and the size of connecting holes are not identical. In this case, the pilot holes in the template need to be aligned for every batch of aircraft and the drill templates with fixed guide holes in them are no longer suitable to the situation. This paper proposes a kind of flexible drill template system which is adjustable for precisely locating and drilling holes on a curved surface of the wing-skin during the period of wing-fuselage connection. The jig system possesses a board of curved surface with continually changing curvature which is designed to fit the wing-skin workpiece. The flexible adjustable modules on the board can be adjusted in lateral and spanwise directions in a range of ±10 mm with a minimum scale of 0.02 mm. The analysis of systematic error and deformation due to operation are also carried out using theoretical model and FE method respectively to verify the validation of the flexible drilling template solution.

Fixtures are used to fixate, position and support workpieces and represent a crucial tool in manufacturing. Their performance determines the result of the whole manufacturing process of a product. There is a vast amount of research done on automatic fixture layout synthesis and optimisation and fixture design verification. Most of this work considers fixture mechanics to be static and the fixture elements to be passive. However, a new generation of fixtures has emerged that has actuated fixture elements for active control of the part-fixture system during manufacturing operations to increase the end product quality. This paper analyses the latest studies in the field of active fixture design and its relationship with flexible and reconfigurable fixturing systems. First, a brief introduction is given on the importance of research of fixturing systems. Secondly, the basics of workholding and fixture design are visited. After which the

“…For reasons such as shorter product life-cycles costs or the shortage of skilled workers, other sectors will adopt more flexible and automated manufacturing systems. Hence, the technologies currently in use within automotive industries will diffuse to other sectors, such as aerospace, References [51,90,93] are some examples of this technology transfer.…”

Fixtures, are used to fixate, position and support workpieces, and form a crucial tool in manufacturing. Their performance influences the manufacturing (and assembly) process of a product. Furthermore, fixturing can form a significant portion of the needed investment and total process planning time for the manufacturing system. Many fixturing concepts, as contribution to increase the flexibility of the manufacturing system, are reported in the literature. The flexible fixturing designs can be classified into the following seven categories: modular fixtures, flexible pallet systems, sensor-based fixture design, phase-change based concepts, chuck-based concepts, pin-type array fixtures and automatically reconfigurable fixtures. It is observed that the more intelligent and automated fixturing systems are designed with the demands for automation in certain industries in mind. Furthermore, different fixturing solutions suit the engineering demands for different manufacturing areas, this means that for the foreseeable future all technologies will remain current. From the self-reconfigurable fixturing techniques a new fixturing capability is emerging: in process reconfigurability for the optimal placement of clamps and supports during the whole process time. These several concepts together with some recent patents are studied here. The paper concludes with some prospective research directions in the field of flexible fixturing.
