Which process is specifically focused on developing technical breakthroughs?

The process that is specifically focused on developing technical breakthroughs is invention. Invention involves the creation of new ideas, processes, methodologies, or products that advance technology or solve specific problems. This process is characterized by creativity and innovation, leading to novel solutions that can impact various fields, including design, engineering, and technology.

In contrast, processes like milling, turning, and abrading are manufacturing techniques used to shape and finish materials. While these techniques are essential in production and engineering, they are more focused on the application and implementation of existing technologies rather than the creation of new, groundbreaking concepts. Therefore, invention stands out as the process dedicated to fostering technical advancements and breakthroughs.
