A cutting tool architecture designed to address the parasitic mechanisms consuming excess power during machining and manufacturing operations-A review-based study towards sustainable manufacturing.

Metal cutting has been extensively studied over the years for improving its efficacy, yet, parasitic mechanisms like chatter and tool wear continue to generate higher forces and energy consumption with poor surface integrity. To address these parasitic mechanisms, a single-point turning cutter design is proposed based on the physics-of-machining including chatter theory to achieve reduced power consumption during the cutting of various metallic alloys like Al-6061, Ti-6Al-4V and others used by critical sectors such as aerospace and automotive. The current work focuses on aspects of machining that effectively reduce parasitic forces feeding into cutting power.

Frugal manufacturing in smart factories for widespread sustainable development.

Manufacturing is a crucial activity of product development that feeds into and is also influenced by the design process. Any material conservation gained during manufacturing directly affects the green credentials of a product. Manufacturing waste can be contrived to approach zero through a recently developed that quantifies resource conservation at all stages of development of a product engineered for frugality.

On complex systems of adaptive frugal products.

products possess a proper mix of features including minimal consumption of resources, good functionality under nominal conditions and low cost. Therefore, increasing use of products, that are designed and also fabricated systematically, is crucial to all-round . However, their low factor-of-safety rigorous-design makes them inherently prone to failure under conditions of overloading.

The science underlying frugal innovations should not be frugal.

In recent years, products of the grassroots and advanced types are being widely used due to their nature and also affordability. However, despite the origins of at grassroots level, grassroots innovations continue to be fabricated in an ad hoc manner that precludes application of science and are thus susceptible to premature failure. This work advocates the use of scientific principles for developing products in general with emphasis on and new design methodologies that are rooted in science to save resources, and hence lower costs, while aiming for robust product functionality.

Revisiting classical design in engineering from a perspective of frugality.

The conservative nature of design in engineering has typically unleashed products fabricated with generous amounts of raw materials. This is epitomized by the whose values higher than unity suggests various uncertainties of design that are tackled through material padding. This effort proposes a new called the that could be used in ecodesign and which addresses both rigors of the design process and quantification of savings in materials going into a product.
