SOLIDWORKS — SHEET METAL DESIGN METHODS
Sheet Metal Tool Bar: To activate the toolbar on the ribbon simply RMB click on any ribbon tab and check the Sheet Metal box.
There are specific sheet metal features we can use to create sheet metal body quickly. However, in some circumstances when the design requires certain types of geometry, you can use non-sheet metal feature tools, then insert bends or convert the part to sheet metal. It is important when designing with sheet metal to think about the best approach to design the part. Although it may appear that using non-sheet metal features (such as extrudes and shells) and then inserting bends or converting to sheet metal is quicker, these options are also the least (ít ra, ít nhất) flexible (linh động, linh hoạt). When designing sheet metal parts, the order of design preference is –» Base Flange –» Edge Flange –» Mitter Flange –» Insert Bend Featutes –» Convert to Sheet Metal. When using the Insert Bends and Convert to Sheet Metal features, it is best to apply them as early as possible during part design, preferably right after you create the first non-sheet metal feature.
Sheet Metal Feature:
Sheet Metal Part: When create a sheet metal part, use the Base Flange tool with an open or closed profile sketch.
Create a Base Flange Feature: Sketch an open or close contour —» Insert —» Sheet Metal —» Base Flange —» Direction (select extrusion direction) —» Depth —» Sheet Metal Parameters —» Thickness (specify requirements and reverse direction if needed.) —» Bend Radius (.04 is minimum) —» Bend Allowance (if K-Factor, Bend Allowance, or Bend Deduction is selected, enter a value. If Bend Table or Bend Calculation is selected, select a table from the list, or click Browse to browse to a table) —» Auto Relief (if Rectangular or Obround is selcted, select Use reief ratio or clear Use reief ratio and set a value for Relief Width and Relief Depth). —» OK.
Convert a solid part to a sheet metal: Non-sheet metal features like Base Extrude, Shell, Rip, and Insert Bends can be build into a part and then insert sheet metal bends. Example: Conical bends are not supported by sheet metal features such as Base Flange and Edge Flange. Therefore, build the part using extrusions, revolves, and so on, then add bends to the conical part. First...
SOLIDWORKS SHEET METAL FEATURES
Corner Weld Beads: Open sketch —» Smart Dimension —» click one line —» Ctrl and click the second line —» move the pointer to show the angular dimension preview —» place the angular dimension —» OK
Break a Corner: Sheet Metal —» Corners —» Break Corners/Corner-Trims —» Break Corner Options —» select Corner Edges and/or Flange Faces —» select a Break type: Chamfer or Fillet —» select a value for Distance (chamfer) or Radius (fillet) —» OK.
Unfold/Fold: Useful when adding a cut across a bend. First, add an Unfold feature to flatten the bend. Next, add your cut. Lastly, add a Fold feature to return the bend to its folded state. Unfold and fold only the bends that needed for the task.
Hem Feature: Select Hem —» select edge to hem —» choose hem outside or inside —» select hem type (closed, open) —» Shown (teardrop or rolled) —» input value/distance to hem —» OK.
Jog Bend: Jog tool adds material to a sheet metal part by creating two bends from a sketched line. The sketch must contain only one line and the bend line does not have to be the exact length of the faces you are bending. To create a jog feature on a sheet metal part —»
USING FORMING TOOLS WITH SHEET METAL
Using Forming Tools with Sheet Metal: If you drag a forming tool (ex: louver) from Design Library onto a sheet metal part surface and it landed sideway/wacky. Here is the solution —» goto Design Library —» select forming tools folder —» RMC —» selected/checked Forming Tool Folder —» select Yes to mark this folder as a forming tools folder.
Note: Before you apply forming tools to sheet metal part, in the Design Library you must designate it folder/contents as forming tools otherwise it will be treated as part file (*.sldprt), not Form Tool file (*.sldftp).
S O L I D W O R K S MULTIBODY SHEET METAL PARTS
Multibody Sheet Metal Parts: To create complex sheet metal designs. Multibody sheet metal parts can consist of multiple sheet metal bodies or a combination of sheet metal and other bodies such as weldment bodies. Each body has its own sheet metal and material definition, flat pattern, and custom properties. These body-related properties can be used in BOMs and drawings. Each body can be isolated and displayed individually in drawings. To be continous...
