This project aims to analyze and design the tool manufacturing process for building a structural component. What are the different steps in the process, how the tools required for manufacturing can affect the total cost of the process and how can it be optimized.
Before any tool design or manufacturing analysis a component analysis was made to stablish the material quantity required for the process and how the optimal distribution when reducing costs.
Total length = 43.71 mm
Total width = 95.42 mm
The positioning of the component was studied for simple and double configuration, that is with one or two press punches. In order to maintain a model that accounts for chain manufacturing, the material must be positioned for all the components to be attached until the last press punch.
Another approach is using cutting taps that don't involve material elimination, this would save 4 mm when separating components and would reduce time and material.
When considering manufacturing processes that imply high volume of components, an economic study is essential. A study for both simple and double configurations was performed analyzing the variables from the designing step adding the machinery, material and operation costs.
The graphs below represent the long term cost for simple and double configuration and also the cutter tap with and without material elimination. The variation for configurations is very low since the process is practically the same, in the case of different cutter tap there is a visible variation in costs.
The manufacturing process will be divided in three steps or "matrix steps":
Previous cutting matrix: The material is introduced in the machine through the guidelines to apply the holes, right width and lengths.
Bending matrix: The final component is bent in the right configuration
Final cut matrix: Components are separated individually and an additional hole is made for piece positioning.
A component design is presented along with the different steps of the process in different views. The whole study was made to a very simple component but the optimization procedure while basic it still can be applied for more complex designs.
The conclusion is that material designs are important for material reduction but the analysis of different processes that account for non material elimination have a stronger impact in the cost reduction of the whole manufacturing process.
