Some PCB test fixtures can be used for edge connector functional testing. ICT can be performed with a bed-of-nails test fixture or with a flying probe setup. Jig and Fixture Design General Information All six degrees of freedom, along X, Y, and Z axis, both laterally and rotationally, need be constrained for a part to be fully located. Strain moves from, tures the part in a comparatively small distance and, goes to 50%. Two scales were used to ident, of the part as shown in Figure 14(b). Thickness is not uniform throughout this, region and the minimum thickness was observed in the, middle of this region for all the three cases. Expertise in a surfacing software like CATIA. Tooling & Fixture Design. But some semi- crystalline materials achieve a relatively low level of crystallinity that is highly dependent upon processing conditions. Going beyond just producing die and molds, we can design and build secondary tooling that provides you with single source continuity along your manufacturing process. For case A, the circular region is observed. Indeed, it can be cited firstly, those concerning tooling used for forming (sheet fixing device and forming tool) [15][16], ... 8,9 In spite of several lucrative advantages, the major setback for SPIF process is its higher fabrication time for which the productivity of the component drastically reduces. This article will explain about the places where the jigs are used and where the fixtures are used. The formability of St-St bilayer sheet in SPIF was measured in terms of maximum wall angle. Fixture (tool) A fixture is a work-holding or support device used in the manufacturing industry. However, these crucial resul, that the fixture’s dynamics were not impacting signifi-, Thickness reduction percentage for all the three cases, are observed in localized regions and shows that the, freedom to move.

Keywords: Sheet Forming. The ISF tool is mounted on the, CNC machine, and a 4-axis dynamometer is used to. It is observed that the proposed process is able to reduce thinning as much as about 300%, considering same forming depth for incremental sheet metal forming and incremental stretch drawing processes. This research describes the theoretical, simulation and practical background of the designed system. It was also found that to successively deform the bilayer sheet into the desired shape, it is necessary for the sheet to be heated above the critical temperature during fabrication to facilitate good bonding between two sheets. A superior reflector design assures more light is directed toward the pool bottom to further increase intensity and color effects, while minimizing glare. The bond strength and critical strain energy release rate (CSERR) were measured to characterize the interface of St-St bilayer sheet. that consists of a, attachment screws. and hold the tool stick while it is rotating (Figure 7(a)). DC01 sheet was used as the test material. The analysis is based on statistical methodologies which made it possible to establish, using the multiple regression method, predictive analytical models for the different responses. The main advantages of this process over conventional forming processes are reduced setup cost and manufacturing lead time, as it eliminates the need of special purpose dies, improves formability, reduces forming forces, and provides process flexibility. 1.1 PURPOSE .
