In this video, I have explained the practical approach to fixture changeover design, covering the engineering principles behind locating pin and bush selection, locating accuracy, pin to hole clearance, tolerance stack-up analysis, repeatability, and poka-yoke.
I have also explained the mechanical design of quick mounting arrangements, tooling retention, and the ergonomics of installing and removing both top and bottom tooling.
The focus is on applying DFMA principles to minimize unnecessary components, simplify assembly, reduce changeover time, and maintain consistent positioning accuracy across multiple tooling setups.
The objective is to understand how to design a quick-change fixture system that is mechanically robust, easy to manufacture, and suitable for repeatable production use.
