As sheet metal parts are flattened (or formed if you start with a flat state), Pro/SHEETMETAL utilizes a "Y factor" to allow for the fact that metal is elastic and stretches as it bends. Pro/SHEETMETAL will subtract from the actual length of the material to compensate for the elasticity. BLANK DEVELOPMENT For Formed Sheet Metal Parts There are many systems employed by a variety of industries (aircraft, electronics, architectural, automotive, etc.) to account for "what happens in a sheet metal part when bending it from its flat blank state to Its final bent-upform: "Setbacks ", "Bend Allowances " and "K Factors " are somewhat

In my previous post I talked about K-Factor, Bend Allowance and Bend Deduction and what they mean in sheet metal design. Now let’s see how we can obtain these values for a specific sheet. As I mentioned in my last post you need to do some tests to calculate these values for a specific sheet. These K-Factor is a ratio that represents the location of the neutral sheet with respect to the thickness of the sheet metal part. When you select K-Factor as the bend allowance, you can specify a K-Factor bend table. The SolidWorks application also comes with a K-Factor bend table in Microsoft Excel format.

Start a new sheet metal part based on Sheet Metal (in).ipt 2. Click on Sheet Metal Defaults 3. Click the pencil icon to edit the unfold rules 4. Create a new unfold rule called .40 k Factor 5. Change the k factor to .40 ul and save it 6. Create a new unfold rule called BendTable using …

Sheet Metal: Understanding K-Factor. SOLIDWORKS sheet metal tools are relatively straight forward, but may not be clearly understood. In sheet metal, there is a powerful bend constant known as the K-Factor. It ultimately allows you to estimate the amount of stretch without knowing what … The sheet metal wall thickness The sheet metal default bend radius The bend allowance/bend deduction of the sheet metal (specified in K-factor) By configuring and utilizing a sheet metal gauge table, we can speed up the process of selecting the correct wall thickness (based on gauge value) and

Mold Design and Casting Sheetmetal Model Analysis The K-factor is defined mathematically as t/Mt, where t is the neutral axis location and Mt is the material thickness. Because of the specific properties of any given metal, there is no easy way to calculate that value perfectly, hence the chart in Figure 2. The K-factor is usually somewhere between 0.3 and 0.5.

I am assuming the bend radii and k factor would be different for a SS since it is harder than regular sheet metal. For instance right now in solidworks for say 11 GA sheet metal I use a bend radii of 0.005 and a k factor of 0.275 and that seems to work pretty well when I put the flat views on my prints.
