3 Assembly Modeling with SolidWorks Project 3 Project Objective Create the 2AXIS-TRANSFER Assembly. Design the PLATE-B Part in context of the GUIDE-CYLINDER and SLIDE-TABE Assemblies. Create configurations for the following SMC assemblies: GUIDE-CYLINDER. SLIDE-TABLE. Create configurations for the new 2AXIS-TRANSFER Assembly. Project Situation The 2AXIS-TRANSFER Assembly is the second sub-assembly for the 3AXIS-TRANSFER Assembly. Develop the second sub-assembly. The 2AXIS-TRANSFER Assembly combines the GUIDE-CYLINDER Assembly and the SLIDE-TABLE Assembly. The SLIDE-TABLE Assembly vertically lifts the GRIPPER two fingers 100mm. The GUIDE-CYLINDER Assembly moves 100mm horizontally. The SLIDE-TABLE Assembly cannot be fastened directly to the GUIDE-CYLINDER Assembly. Design the PLATE-B Part as an interim part to address this issue. GUIDE-CYLINDER Assembly SLIDE-TABLE Assembly Create the configurations for the GUIDE-CYLINDER, SLIDE- TABLE and 2AXIS-TRANFER sub-assemblies to represent physical positions. 2AXIS-TRANSFER Assembly PAGE 3-3

4 Assembly Modeling with SolidWorks Project Overview Develop the 2AXIS- TRANSFER Assembly. The 2AXIS-TRANSFER Assembly consists of the following items: GUIDE-CYLINDER Assembly. PLATE-B Part. SLIDE-TABLE Assembly. SHCS. GUIDE-CYLINDER Assembly PLATE-B Part SLIDE-TABLE Assembly 2AXIS-TRANSFER Assembly PLATE-B is a new part developed in context of the GUIDE-CYLINDER Assembly. Create two configurations for the GUIDE-CYLINDER Assembly. The GUIDE-CYLINDER Configurations are named Normal and Extended. Normal Extended GUIDE-CYLINDER Configurations Create two configurations for the SLIDE-TABLE Assembly. The SLIDE- TABLE Configurations are named Normal and Extended. Normal Extend ed SLIDE-TABLE Configurations PAGE 3-4

5 Assembly Modeling with SolidWorks Combine the GUIDE-CYLINDER Normal Configuration and Extended Configuration with the SLIDE-TABLE Normal Configuration and Extended Configuration to create the following four 2AXIS-TRANSFER Configurations: 1. Normal-Normal. 2. Normal-Extended. 3. Extended-Normal. 4. Extended-Extended. The GUIDE-CYLINDER Configuration is listed first, followed by the SLIDE-TABLE Configuration. Create the fifth 2AXIS-TRANSFER Configuration named Fastener. SHCS are unsuppressed in the Fastener Configuration. SHCS are suppressed for the other four configurations.

6 Assembly Modeling with SolidWorks Top Down Design Assembly Modeling Approach In the Top Down Design assembly modeling approach, major design requirements are translated into assemblies, sub-assemblies and components. You do not need all of the required component design details. Individual relationships are required. There are two methods to begin a Top Down Design Assembly approach: Method 1: Start with a Layout Sketch in the assembly. Method 2: Start with a component in the assembly. Use Method 2 in this project. Use Method 1 in Project 6. All major components are positioned based upon a 2D sketch. Relationships between sub-assemblies must be maintained for proper fit. Delivery Station Layout Sketch Use Method 2 for the PLATE-B Part. Develop the PLATE-B Part with an existing component in the GUIDE- CYLINDER Assembly. The PLATE-B Part contains In Context Relations. An In Context Relation is a reference between a sketch entity in a part and an entity in another part. Relations that are defined in context are listed as External references. In Context relations and External references are powerful tools in the design phase. Begin with an empty part and utilize existing components in the assembly. Determine the geometric and functional requirements of the part. PAGE 3-6

7 Assembly Modeling with SolidWorks Assembly modeling techniques with in context features requires practice and time. Planning and selecting the correct reference and understanding how to incorporate changes are important. Explore various techniques using In Context Mates and External references developed in context of another part. Assembly Modeling Techniques with In Context Mates: 1. Plan the Top Down Design method. Start from a Layout sketch or with a component in the assembly. 2. Prepare the references. Utilize descriptive feature names for referenced features and sketches. 3. Utilize InPlace Mates sparingly. Load all related components into memory to propagate changes. Do not use InPlace Mates for purchased parts or hardware. 4. Group references. Select references from one component at a time. 5. Ask questions! Will the part be used again in a different assembly? If the answer is yes, do not use In Context Mates. If the answer is no, use In Context Mates. 6. Will the part be used in physical dynamics or multiple configurations? If the answer is yes, do not use In Context Mates. 7. Examine how to redefine External references. Use List References and Lock References to locate and protect geometry. Existing references do not update in a locked state. Locate the locked references. Create new references for the sketch and the feature. 8. Reduce the size of the FeatureManager. Hide Update Holders for in context features. 9. Work in the Edit Part mode to obtain the required external references in the assembly. Create all non-referenced features in the Part, not in the assembly. 10. Obtain knowledge of your company s policy on In Context Mates or develop one as part of an engineering standard.. Note: Using the Break All command causes External references from updating. Note: The Break All command is not utilized in this project. The authors prefer other techniques based upon experience. PAGE 3-7

43 Assembly Modeling with SolidWorks Project Summary In this project you utilized a Top Down Design Assembly modeling approach with in-context features. You developed the 2AXIS-TRANSFER Assembly. The 2AXIS-TRANSFER Assembly consists of following: GUIDE-CYLINDER Assembly. PLATE-B Part. SLIDE-TABLE Assembly. SHCS Part. You created the PLATE-B Part in context of the GUIDE-CYLINDER Assembly and SLIDE-TABLE Assembly. Interference problems were detected and resolved before any parts were manufactured. You built configurations for the GUIDE-CYLINDER Assembly and the SLIDE-TABLE Assembly. The GUIDE-CYLINDER Configurations and SLIDE-TABLE Configurations were combined to form the 2AXIS- TRANSFER Configurations: Normal-Normal, Normal-Extended, Extended- Normal, Extended-Extended. Review the assemblies with your project team leader. Ask if the customer has provided any additional input that would constitute a design change. For now, there are no changes. There will be changes in the future. Planning your assembly and configurations is key to your success. How do you control positions of the ROTARY-GRIPPER assembly? Answer: Utilize Configurations in Project 4. Review the questions and exercises before moving on to Project 4. PAGE 3-43
