SW2009 Expanded Sheet Metal Gauge/Bend Table

Discussion created by 1-64TBX5 on Nov 19, 2008
Hello everyone.

The company that I work for is beginning to switch to Solid Works from another CAD package and I am the person who was selected to do all of the Ginny pig work.

I'm trying to get everything setup to where the other users in the company, simply need to select what material thickness they want to use and which bend radius they wish to use. An issue that I'm dealing with, is that my company has found through trial and error that the K-factor needs to change when we change bend radius.

For example, with 12ga (.105in) we normally use a .156in bend radius with a k-factor of .49 but we also use a .117in bend radius with a k-factor of .41. Well, I would like to have SW setup to where our designers do not have to remember to change the k-factor when the need to make this change to the bend radius.

So the other day when I was reading though the notes about the new features of SW 2009 and I stumbled across something called "Expanded sheet metal gauge/bend table" and the notes on it says "The sheet metal gauge table has been expanded to let you associate the bend allowance, bend radius, or k-factor with any combination of thickness, bend radius and material" So when I read this I thought "great this should do what I need".

I have included the sample table that SW provided as sample.zip

Well I began creating a test table to see if I could make everything work on my own and yes I can create a table that works but I cannot create the table that I need and have that table work. I have attached the table that works as works.zip and the table that dose not work as my_wish.zip.

I have been playing with this table for a couple of days now and what I have been observed is this.

1. If the bend radius in the second column is less than the bend radius in the first column. SW will use the K-factors from the first column.

2. If the bend radius in the second column is not significantly greater than the bend radius in the first column, SW will use the k-factors from the first column. For example, I had the bend radius in the first column at .120 and if the bend radius in the second column was .209 or less, SW would use the k-factors from the first column but if the bend radius was .210 or more, SW would use the k-factors from the second column as you would expect it to.

Well hopefully everyone was able to follow this post and hopefully someone will have a clue to what's going on here. Oh by the way I did install service pack 1 yesterday and it did not help my problem.
