  1. MECH251LABORATORY CLASS SolidWorks & 3D printerlearning

  2. No eating and drinking No smoking Turn off your mobile phone or use vibration alert only, avoid mobile using inside the room Leave the lab after the class unless you have access card of 4225C LAB Regulations

  3. Name: Quan lulin, Christine email: ppxq@ust.hk Practice hours: Tuesday 10:30AM-13:30AM LAB TA’s information

  4. To learn a popular and powerful 3D CAD software -- SolidWorks To experience designing a real product by using SolidWorks To experience optimizing a design by using Matlab To experience manufacturing a real product by using 3D printer To relate basic concept learnt in the lectures to the CAD/CAM software Objectives of MECH251 LAB

  5. Attendance/Classwork 20% Homework        30% Homework must hand in before the next class Projects                  Project 110% Project 210% Project 330% Project must finished before 9 May 2011 Grade Policy of LAB Class

  6. SolidWorks: 8 weeks Matlab: 1 week Rapid Prototyping manufacturing: 2 weeks Projects: begin from the 7th week Schedule

  7. Projects

  8. Parts, assemblies, and drawings. SolidWorks Fundamentals

  9. Feature based Dimension Driven Solidworks Fundamentals

  10. 3D Design Solidworks Fundamentals

  11. Feature Modeling Solidworks Fundamentals

  12. Terminology

  13. Windows Function User Interface

  14. SolidWorks Document Windows User Interface

  15. SolidWorks Document Windows User Interface

  16. Toolbars( Tools Customize… ) User Interface

  17. System Options Tools Options… User Interface

  18. Sketches. Create the sketches, and decide how to dimension, where to apply relations, and so on. Features. Select the appropriate features, determine the best features to apply, decide in what order to apply those features, and so on. Assemblies. If the model is an assembly, select what components to mate, what types of mates to apply. Design Method

  19. All sketches include the following elements: Plane Sketches

  20. All sketches include the following elements: Origin Sketches

  21. All sketches include the following elements: Dimension Driving Dimension Sketches

  22. All sketches include the following elements: Dimension Driven Dimension Sketches

  23. All sketches include the following elements: Relation Sketches

  24. Fully Defined. All the lines and curves in the sketch, and their positions, are described by dimensions or relations, or both. Over Defined. Some dimensions or relations, or both, are either in conflict or are redundant. Under Defined. Some of the dimensions or relations in the sketch are not defined and are free to change. You can drag endpoints, lines, or curves until the sketch entity changes shape. No Solution Found. The sketch is not solved. The geometry, relations, and dimensions that prevent the solution of the sketch are displayed. Invalid Solution Found. The sketch is solved but results in invalid geometry, such as a zero length line, zero radius arc, or self-intersecting spline. Sketches Definitions

  25. Selecting a starting plane for a sketch Starting a new sketch Accessing and using the sketching tools Dimensioning the sketch and adding and deleting geometric relations Fully defining sketches Sketching

  26. Selecting a starting plane for a sketch Sketching

  27. Accessing and using the sketching tools Sketching

  28. Sketch Entities Line Sketching

  29. Sketch Entities Circle Exercise: Use two methods to sketch the circles below Sketching

  30. Sketch Entities Parallelograms Press Ctrl while dragging to create a parallelogram at any angle. Drag without pressing Ctrl to create a rectangle at an angle Sketching

  31. Sketch Entities Polygon Parameters: Number of Sides Center X Coordinate Center Y Coordinate Circle Diameter Angle Sketching

  32. Sketch Entities Arcs Centerpoint Arc Tangent Arc 3 Point Arc Sketching

  33. Sketch Entities Ellipse 1 Click in the graphics area to place the center of the ellipse. 2 Drag and click to set the major axis of the ellipse. 3 Drag and click again to set the minor axis of the ellipse. Sketching
