GD&T True Position
Position can be useful geometric tolerance in designing sports equipment. For example, properly locating the bolt clearance holes for a new snowboard binding base plate can assure correct assembly on the device and the interchangeability of different brands. Students will
... ContinuedGD&T Runout
Controlling runout is crucial to assure the function of rotating parts. For example, unless a proper runout is specified for a brake rotor, the rotating part may interfere with the other brake components (discs, pads, etc.), causing dangerous vibration during
... ContinuedGD&T DVD Flatness
Designing toys like Lego blocks require using very tight tolerances. Concepts such as the maximum material condition (MMC) and perpendicularity are crucial in assuring that the many types of Lego blocks will fit together. Sample Parts: Download 2-perpendicularity.zip
... ContinuedGD&T DVD Flatness
Flatness is an important concept in manufacturing a data storage device such as a DVD. If a specified flatness is not met during injection molding, the device may not read properly. Student will work through a series of questions to
... ContinuedFundamentals of Design
MIT Professor Alex Slocum’s book is about helping people to learn how to create their own future! It does this by taking advantage of the fact that the reader’s LEFT brain sees the LEFT side (fun) of the book. The
... ContinuedReverse Engineering Using Fischertechnik parts
This lesson explores the reverse engineering process. Students will use a caliper to measure an object accurately and record results in their sketch book. Students will take a Fischertechnik part and convert it to a solid model. Students will take
... ContinuedBuild, Draw, Build
In this lesson wood, foam board, or cardboard is used to improve high school student’s visualization skills, understanding of the manufacturing processes, measurement, and safety. The student builds an abstract object from their drafting book. The builder then takes the
... ContinuedGD&T and SolidWorks
GD&T has also been a challange to create exercises that illustrate part examples that students can relate to. Based on an integrated learning approach, this paper takes you through examples in SolidWorks that apply GD&T where students can see the
... ContinuedModeling a Centrifugal Compressor Wheel
This lesson is to be used as an in class exercise for students whom are taking a beginning SolidWorks course. Students will be exposed to curved surface modeling techniques along with elements of mechanical design. Furthermore, the product from this
... ContinuedSheet Metal Design
This exercise provide step-by-step instructions for students to explore sheet metal functionality. Sheet metal part are created in the 3D formed state and manufactured in the 2D flat state. Students work patterns, forms, and hems. Contributed by Mark Eilers,
... ContinuedLink Properites in the Title Block
This exercise will assist students in learning how to link properities and their values to text in a Title block. Understanding how properties such as mass and material in a part can be linked directly to the drawing is an
... ContinuedProblem Solving with Patterns
Students learn to apply engineering design to solve a real-world manufacturing problem. The following concepts are explored: linear patterns (spacing and direction), circular patterns (angles and axis), using above concepts solve real-world problems. Contributed by Dan Benfield. Lesson Plan: ProblemSolvingwithPatterns
... ContinuedMoment of Inertia Contest
T Students will design a wheel with a 3 inch diameter to go down a 30 degree ramp with the smallest moment of inertia. Lesson includes operations for the wheel to be produced with a 3D Printer. The lesson
... Continued5-Beam Sonar Head
This lesson develops a 5-Beam Sonar Head utilizing cylindrical geometry on multiple planes. Utilizing 35 degree angular cuts, students will develop the skills necessary to create features beyond the top, right, and front planes. The aluminum material property is also
... ContinuedCreating a Worm Using a Sweep Path
This lesson provides experience in designing a worm that will ultimately mate with a worm gear. It will show students how to create a helical path, which they will in turn sweep a closed profile on a cylinder. Contributed by
