Assembly cut options
Assembly cut options
(OP)
Hi all,
I know this has been addressed back on 08/04 but I was hoping for some new thoughts on the process.
Facts:
We have an aluminum extrusion that gets cut to length and then machined. I have this assembly "built" to reflect the involved processes. To begin, we have a SW part to represent the extrusion. Then it becomes an assembly at the "cut to length" stage with the extrusion becoming the component of the cut. Now we machine the assembly. At the "machined" state of the assembly it consists of 2 components, the cut and the extrusion. Basicly, my assembly is really only 1 part with an assembly of processes. I do understand the issue of not being able to "add" material to an assembly, however I need to remove material.
Problem:
At this stage I need to add chamfers to some of the drilled holes and the chamfer option is well, not an option :( I fail to see any logical reasons why this is the case. This is how we must build these to capture the cost of the individual process. I think this producton process is very common in the manufacturing industry so if someone can please explain why a chamfer option is not available it would be appreciated.

However, the Hole Series function (check in the Help files) can create chamferred holes in an assy.

Hopefully this will make things clear as mud.

I am soooo glad it is you and not me having to deal with this assinine system. If you have to do this for each part produced, your final-assy-of-assys/parts must be horrific. Whoever dreamt it up should be frog-marched from the building immediately.
The MRP systems I've dealt with had the "manufacturing process" data input manually by personnel who understood the manufacturing processes, and could derive the times involved from a manufacturing drawing.
To allow an MRP system to dictate the product design is ludicrous. I feel sympathy for you, but all I can do is shake my head in disbelief.

CorBlimeyLimey - Your sympathies are welcomed, but I have to work with systems in place, however backwards they may be :(

I think we discussed this process for castings. I am working on something similar at the moment. Let's see if I understand what you are doing.
You have material extruded as per your fabrication drawing. You machine this material to produce a functional part as per another fabrication drawing. Your MRP must track the extrusions, and it must track the as-machined final parts. Right?
You have set things up in SolidWorks to allow this. It has the additional advantage that your extrusion is locked up by your PDM software, and is accessible to you on a read-only basis. Only your machining drawing that allows you to remove material is readable. It makes perfect sense to me.
I am still on SW2003, and I cannot do rotations at the assembly level. :(
You can do a chamfer by creating a diameter slightly larger than the hole, then extrude it with a 45_degree draft angle. At some point, a sweep might work too.
I would like to see this stuff implmented too.
