Homework Deliverables Due At The Beginning Of Class Monday 0605ins

Create a SolidWorks part model of the wrench shown below. The dimensions are in millimeters. Use equations and dimension choices to incorporate the following design intent. Note some of these might differ from the dimensions given on the figure.

· Large end hex size equal to small end hex size + 5

· Outer diameter of each end (at midplane) is equal to the hex size + 15

· Distance from center of hex to end of straight handle equal to twice the hex size

· Length of straight handle section = (larger hex size – 10) x 10

Create an engineering drawing with a design table. Show the variable dimensions as labels analogous to figure 5.149 (on page 183) in your text.

Use auxiliary views (not sections) for wrench ends and a section view for the wrench handle. Include the dimensions for 20 mm, 30 mm, and 40 mm (large end) wrench configurations in the design table on your drawing. Turn in the following to document your work:

• A printout of your part drawing on B-size (11 x 17) paper.
• Submit your drawing per instructor’s instruction.

The assignment involves creating a detailed SolidWorks model and corresponding engineering drawing of a wrench, emphasizing parametric design and variable dimensions. The key tasks include modeling the wrench with specified geometric relationships, developing a comprehensive drawing with a design table that showcases different size configurations (20 mm, 30 mm, and 40 mm), and accurately representing the variable dimensions through auxiliary views and a section view. This process not only enhances modeling skills but also demonstrates proficiency in creating design tables and utilizing equations to maintain design intent.

In the initial phase, the focus is on developing an accurate 3D model that captures all essential features of the wrench, including the hexagonal ends and the handle, with dimensions driven by equations related to the hex size. The large end hex size should be defined in relation to the small end size, with the outer diameter at the midplane also linked to the hex size, ensuring the model is fully parametric and adaptable to the specified sizes. The model's dimensions follow the provided formulas, allowing seamless updates across different wrench sizes by simply changing the variable parameters in the design table.

The second phase involves creating an engineering drawing that includes a detailed view of the wrench with dimension labels, emphasizing the variable aspects. Auxiliary views provide clear representations of the wrench ends, avoiding the complexity of section views in these areas, while a section view highlights the handle’s internal or sectional features. A design table embedded in the drawing systematically presents the three wrench sizes, with each configuration illustrating the corresponding dimensions for the large end, small end, the handle length, and the outer diameters, based on the predefined variables.

In practicing these techniques, students will learn to use SolidWorks equations effectively, link dimensions to variables, and generate meaningful design tables—skills essential in modern engineering design workflows. The final deliverables include a printout on B-size paper, which must accurately reflect the varying configurations, and adherence to instructor's submission guidelines, ensuring clear communication and documentation of the design process.

The assignment tasks students with creating a detailed, parametric SolidWorks model of a wrench, emphasizing the use of equations and variable dimensions to facilitate multiple configurations. This project not only tests the ability to model complex geometric features but also demonstrates proficiency in developing comprehensive engineering drawings with design tables that capture size variations efficiently. Such skills are crucial in product development and engineering optimization, providing flexibility and precision in designing tools and mechanical components.

The core of the project involves defining the key dimensions of the wrench—such as the hex sizes and outer diameters—in relation to each other through specific equations. These relationships ensure that modifications in the large or small end sizes automatically propagate through the model, maintaining design consistency across different wrench sizes (20 mm, 30 mm, and 40 mm). This approach exemplifies parametric modeling's advantages in engineering contexts, where iterative design changes are common.

Furthermore, the engineering drawing component includes a layout with a design table, which systematically presents each wrench configuration along with its variable dimensions. Auxiliary views are employed to visualize the wrench ends, avoiding the complexity of sections and providing clear, undistorted representations of the feature geometries. Conversely, a section view is used predominantly for the handle region, illustrating internal features or cross-sectional details that are otherwise hidden from external views. These visual techniques collectively communicate the design intent effectively, bridging 3D modeling with 2D documentation.

Practical skills gained through this assignment include crafting equations within SolidWorks, creating and managing design tables, and utilizing auxiliary and section views appropriately. These competencies are vital for engineers and designers to develop adaptable, well-documented mechanical components and tools, fostering efficient manufacturing and quality control processes.

Overall, this assignment underscores the importance of parametric design and detailed documentation in modern engineering. The completed project demonstrates an integrated understanding of geometrical relationships, visual communication through engineering drawings, and effective documentation strategies—all essential for professional engineering practice. The final deliverables—an accurate, multi-configuration drawing and a robust SolidWorks model—serve as tangible proof of developing technical skills and understanding complex design principles.
