we have an on-going project about designing a kitchen shelf by using aluminum extrusion components. One of the requirements is to “solve all the functionalities through the extrusion’s section by avoiding working successively with the extrusion itself. (Eg. carrying out if pitch drillings)”
Does it mean we should design it by using extrusion components as less as possible or we may not always use extrusion instead of using other technologies such as drilling to reach our design ?
And does anyone know anything about modularity betwwen 2 hanging parts ?
Any adivice will be appreciated !!!
These sound like questions that you should address to you instructor.
“Pitch drillings” I have no understanding of. “Drilling” yes; pitch drilling, no.
Machine screw threads have “pitch” and are generally “tapped” into a hole (2 steps: drill and then tap) ; self-tapping screws are also used and require only one step; drill a hole.
"solve all the functionalities through the extrusion’s section by avoiding working successively with the extrusion itself…
I interpret this to mean: design the “cross section” of the extrusion to incorporate as many uses as possible to avoid secondary operations; drilling and tapping, grinding, milling, punching, etc. Anything detail that is obtained as the material is extruded is basically free of added expense; add other manufacturing steps and cost goes up.
An example might be; including a “T” recess in the extrusion to enable a 90-degree twist-fastener to mount a panel, instead of having to drill and/or tap a hole for a screw. Or possibly an extruded groove that would, in combination with a panel detail, allow the panel to be mounted without any additional fasteners.
