In the field of product design and engineering, understanding the differences between chamfers and fillets is crucial. My new blog post at https://www.sogaworks.com/blogs/chamfer-vs-fillet/ delves into this topic. It examines where chamfers and fillets are needed, how to choose between them, and how to design chamfers to save costs. This exploration is based on considerations of safety, process requirements, and appearance decoration. It also takes into account factors such as stress concentration, assembly relationships, and processing efficiency. Recommended for those interested in improving their understanding of product design.
