This thesis examines geometric process planning in four-axis rough machining. A review of existing literature provides a foundation for process planning in machining; efficiency (tool path length) is identified as a primary concern. Emergent structur

PurposeSubtractive rapid prototyping (SRP) uses layer‐based removal from a plurality of orientations in order to create geometry in a highly automated manner. However, unlike additive means, the method can be inefficient due to redundant cutting op

Implementations of roll to roll contact lithography require new approaches towards manufacturing tooling, including stamps for roll to roll nanoimprint lithography (NIL) and soft lithography. Suitable roll based tools must have seamless micro- or nan

Scaling contact lithography (microcontact printing, microflexography, and nanoimprint lithography) to large roll-to-roll platforms will enable high speed, low cost lithographic patterning of surfaces. However, many details of robust implementations a

Microcontact printing is a versatile patterning technique, but is often limited by deformation of the stamp pattern. This paper examines the sensitivity of stamp pressure distributions to variations in displacement when the microcontact printing stam

This paper describes the development of an articulating endoscopic screw driver that can be used to place screws in osteosynthetic plates during thoracoscopic surgery. The device is small enough to be used with a 12 mm trocar sleeve and transmits suf

This paper examines the phenomenon of emergent structures that occur in the transient stock material during multi-axis rough machining from a plurality of fixed orientations. Taking the form of thin webs and strings, emergent structures are stock mat

This paper develops a general model for the load-displacement behavior of polymer microfeatures, such as those encountered in polydimethylsiloxane (PDMS) stamps for soft lithography. Soft lithography is an attractive low-cost method of patterning sur

The material and product accuracy limitations of rapid prototyped products can often prevent the use of rapid prototyping (RP) processes for production of final end-use products. Conventional machining processes are well-developed technologies with t
