A new rapid prototyping system using universal automated fixturing with feature-based CAD/CAM

Using Palletised Work-Holding to Emulate 5-Axis Machining of Aerospace Components in the Developing World

“…Choi et al [7] mentioned that if the part could be magnetically suspended in the air, all sides could be machined without changing the set-up. The result would be a single machine set-up that is often called 'complete machining'.…”

Feature-Based Design – An Overview

“…Examples can be found in references [13] [33] [9]. Although most of the currently available applications and systems work by using an objectoriented structure (i.e.…”

Process planning for fixturing of custom machined implants

“…Choi et al in their report identify location, support and hold as the three critical purposes of fixturing [21]. The cost of designing and fabricating fixtures can amount to 10-20%of the total manufacturing system costs [18], which is a significant portion.…”

“…The cost of designing and fabricating fixtures can amount to 10-20%of the total manufacturing system costs [18], which is a significant portion. This technique introduces thermal shrink and expansion problems [21]. Some adhesive techniques like Light Activated Adhesive Gripper (LAAG) [22] and Photo Adhesive Workholding (PAW) [23] have also been developed.…”

“…requires lot of technical skill and these lack the flexibility to handle parts of arbitrary shapes. One of the flexible fixture solutions is the Reference Free Part Encapsulation (RFPE) developed by Choi et al which exploits the property of phase change of materials[21]. Phase changes may be temperature induced, electrically induced or a combination of the two.…”
