Looking at the profile, the part looks like a flat piece and not curved as before, so we need to add a guide curve:Įxpand Guide Curves in the Property Manager. Now, edit the sweep and replace 3DSketch1 with Sketch 2. Moving the rollback bar down past Sketch1, I edit Sketch1, add the straight construction line and add a pierce relation between the endpoint of the line and Sketch2: Now I will modify the profile sketch so that it relates to the new path by adding a construction line that ties them together. I’ll create a new sketch on the front plane and use Convert Entities on the 3D sketch to get a 2D projection (Sketch2 is the new sketch). Now I can use the roll back bar to go back to the 3D sketch: I want this profile to be perpendicular to the Axis, so I’m going to create a new profile and use the 3D sketch as a guide curve:įirst, I’ll flatten the tree to see how the part was created sequentially by holding and pressing. Taking a look at a section cut from the top view, notice that the profile of the part is twisted in relation to Axis1. The profile and path sketches are shown, and this part was made with a rectangular profile swept around a 3D sketch:
SOLIDWORKS TUBE BENDING FREE
Here is a sweep that looks like a Mobius Strip (feel free to look this up if high school math was a while ago like it was for me). The second aspect I’m going to cover is using a guide curve to control the sweep. This is because the cut is parallel to the profile: If we take the same section cut as before, the section looks round.
SOLIDWORKS TUBE BENDING FULL
The diagonal section looks thinner instead of being a full round like before: If we edit the feature, we can change the orientation to “Keep normal constant”: Notice how profile looks like an ellipse, this is because the section cut is parallel to the same plane as the profile: Here is the part shown sectioned at a diagonal leg. The default is set to “Follow Path”, so let’s see what that looks like when we hit the green check and create the part: To illustrate this difference, here is a part with 2 sketches to create a simple piece of pipe with a circular profile and a bent path:Īfter going into the Swept Boss/Base feature (under the Features tab on the Command Manager) and choosing the profile and the path, expand the Options area to view the Orientation/twist type. This can come in handy if you have something like plastic tubing that’s profile can distort after you bend it. In contrast, the Keep normal constant makes the profile normal to itself. This means if you look at a cross section normal to the path anywhere, the profile will be constant. To summarize, when the Follow Path option is used the profile will be normal to the path. Thanks to the high quality of our CNC tube bending machines we are able to work any kind of metal, from the smallest medical tube to the large oil pipe. As CNC tube bending machine suppliers we manufacture 4 different types of pipe bending machines which can be customized from 1 up to 14 electric axes. These are 2 of the Orientation/twist types under the Options pane in the Properties Manager when creating your sweep. Italian tube bending machines to meet any bending need. The first thing I want to focus on is the difference between Follow Path and Keep normal constant. Since I’m sure you’ve mastered this, let’s move on to some more advanced sweep feature functions. I will be focusing on the swept boss/base feature, but this can also apply to a swept cut. If you have been paying attention to my blogs (it’s okay if you haven’t), you’ll recall that I wrote an article on the basics of creating a sweep in SOLIDWORKS.
