Rough Sketch of Design Situation: CUSTOMER assembly An assembly combines two or more parts. In an assembly, parts are referred to as, ‘components, Design constraints directly influence the assembly design process. Other considerations indirectly impact the assembly design, namely: cost, manufacturability, and serviceability PAGE?-&Fundamentals of Assembly Modeling Project Overview ‘Translate the rough conceptual sketch into a SolidWorks assembly. ‘The GUIDE-ROD is the first assembly. Determine the first component of the assembly. Parallel Mato Fixed Component GUIDE-ROD assembly The first component is the GUIDE. The GUIDE remains stationary. The GUIDE is a fixed component. The action of assembling components in SolidWorks is defined as Mates. DE aa assembly Mates are relationships between components that simulate the construction of the assembly ina manufacturing environment. The CUSTOMER assembly combines the GUIDE-CYLINDER assembly with the GUIDE-ROD assembly. Assembly Modeling Approach CUSTOMER assembly In SolidWorks, components and their assemblies are directly related through @ common file structure. Changes in the components directly affect the assembly and vise a versa. You can create assemblies using the Bottom-up assembly approach, Top-down assembly approach, or a combination of both methods. ‘This chapter focuses on the Bottom-up assembly approach. The Bottom-up approach is the traditional method that combines individual components. Based on design criteria, the components are developed independently. ‘The three major steps in a Bottom-up assembly approach are: Create each component independent of any other component in the assembly, insert the components into the assembly, and mate the components in the assembly as they relate to the physical constraints of your design. PAGE?-5Engineering Design with SolidWorks 2008 In the Top-down assembly approach, major design requirements are translated into assemblies, sub- assemblies, and components. AK tn the Top-down approech, you do not need al of the required component design details. Individual relationships are required, Example: A computer. The inside of a computer can be vided into individual key sub-assemblies such as a: motherboard, disk drive, power supply, ete. Relationships between these sub-assemblies must be maintained for proper fit. Use the Bottom-up design approach for the GUIDE-ROD assembly and the CUSTOMER assembly. Linear Motion and Rotational Motion In dynamies, motion of an object is described in linear and rotational terms. Components possess linear motion along the x, y, and z-axes and rotational motion around the x, y, and z-axes. In an assembly, each component has six degrees of freedom: three translational (linear) and three rotational. Mates remove degrees of freedom. All components are rigid bodies. The components do not flex or deform.

The following features can be associated with a Smart Component: Simple holes, Hole Wizard holes, Extruded Boss and Cut, and Revolved Boss and Cut. Column 3: The MGPTube part is fixed (f). You can fix the position of a component so that it cannot move with respect to the assembly Origin. By default, the first part in an assembly is fixed; however, you can float it at any time. It is recommended that at least one assembly component is either fixed, or mated to the assembly planes or Origin. This provides a frame of reference for all other mates, and helps prevent unexpected movement of components when mates are added. The Component Properties are: f ‘Component Properties in an assembly: ~ | Symbol: | Relationship: oO | A minus sign (-) indicates that the part or assembly is under-defined and requires | additional information.

Column 4: MGPTube - Name of the part. Column 5: The symbol <#> indicates the particular inserted instance of a component. The symbol indicates the first inserted instance of a component, “MGPTube” in the assembly. If you delete a component and reinsert the same component again, the <#> symbol increments by one. Column 6: The Resolved state displays the MGPTube icon with an external reference symbol, “- >”. The state of external references is displayed as follows: © Ifa part or feature has an external reference, its name is followed by >. The name of any feature with external references is also followed by >. © Ifan external reference is currently out of context, the feature name and the part name are followed by >? © The suffix ->* means that the reference is locked. © The suffix ->x means that the reference is broken. PAGE 2-16Engineering Design with SolidWorks 2008 AX There are modeling situations in which unresolved components create rebuild errors. In these situations, issue the forced rebuild, Ctrl+Q. The Ctrl+Q option rebuilds the model and all its features. If the mates still contain rebuild errors, resolve all the components below the entry in the FeatureManager that contains the first error. Mate Types Mates provide the ability to create geometric relationships between assembly components. Mates define the allowable directions of rotational or linear motion of the components in the assembly. Move a component within its degrees of freedom in the Graphics window, to view the behavior of an assembly. ‘Mates are solved together as a system. The order in which you add mates does not matter. All mates are solved at the same time. You can suppress mates just as you can suppress features. ‘The Mate PropertyManager provides the ability to select either the ‘Mates or Analysis tab, Each tab has a separate menu, The Analysis tab requires the ability to run COSMOSMotion. The Analysis tab is not covered in this book. The Mate PropertyManager displays the appropriate selections based on the type of mate you create. ‘The components in the GUIDE-ROD assembly utilize Standard Mate types. Review the Standard, Advanced, and Mechanical Mates types. Standard Mates: ‘Components are assembled with various Mate types. The Standard Mate types are: Coincident Mate: Locates the selected faces, edges, or planes so they use the same infinite line. A Coincident mate positions two vertices for contact Parallel Mate: Locates the selected items to lic in the same direction and to remain a constant distance apart. Perpendicular Mate: Locates the selected items at a 90 degree angle to each other. ‘Tangent Mate: Locates the selected items in a tangent mate. At least one selected item must be either a conical, cylindrical, spherical face. Concentric Mate: Locates the selected items so they can share the same center point.

Additional information on Mate Diagnostics is located in the ‘What’s New section, Design Library A parts library contains components used in a design creation. The SolidWorks Design Library provides examples of common industry components for design creation. ‘The Design Library consists of annotations, assemblies, features, forming tools, parts, Toolbox (Add-in) and 3D ContentCentral (models from suppliers). SolidWorks Add-ins are software applications. Your company issued a design policy. ‘The policy states that you are required to only use parts that are presently in the company’s pars library. The policy is designed to lower inventory cost, purchasing cost, and design time. In this project, the SW Design Library parts simulate your company’s part library. Utilize 2 hex flange bolt located in the Hardware folder. Specify a new folder location in the Design Library to quickly locate the components utilized in this project. * The Design Library saves time locating and utilizing components in an assembly. ‘Note: In some network installations, depending on your access rights, additions to the Design Library are only valid in new folders.
