Design and analysis of reconfigurable discrete dies for sheet metal forming

Reconfigurable Tooling by Using a Reconfigurable Material

“…5. illustrates the parameters related to the reconfigurable process: design and manufacture of the pin heads; since its shape, size and length play an important role in the arrangement of the closed matrix (Walczyk, 1998).…”

“…A pin head must be strong enough to support the mechanical and thermal loads of the material to manufacture avoiding the problems in the final piece such as bending, buckling and dimpling (Walczyk, 1998). In addition to normal or vertical load, the pin will be subjected to lateral load depending the height and of the adjacent pins on the shape; this variable is a key factor on the pin head design (Schwarz, 2002), as shown in Fig.…”

Simulation and estimation of parameters in reconfigurable multipoint forming processes of plates in the creep mode

“…In works [16][17][18][19] design features of rod systems are considered and the main approaches to definition of the loads acting on each rod element are proposed. Results of searches for the most rational form of rod element are also presented.…”

A method for representation of component geometry using discrete pin for reconfigurable moulds

“…Academically, the research group led by Prof. D. Hardt at Massachusetts Institute of Technology (MIT) [20][21][22][23][24] was the original pioneer in the field of reconfigurable pin tooling during the 1980s and 1990s and accordingly conducted systematic analyses into the impact of discrete pins on moulded components and optimization of pin mould design.…”
