Introduction:
In this lesson, students will learn to create a solid model of a shaft collar. The creation of the shaft collar begins with the creation of a cylinder. The cylinder is modified by subtracting or cutting away a concentric cylinder through which the axle will pass.. The step by step CAD tutorials for the creation of the shaft collar are covered in pages 1-18 through 1-27 of Marie Planchard’s SolidWorks CAD tutorial.
This lesson provides an excellent opportunity for the introduction of Area and Volume concepts and calculations.
Objective:
Students who complete this lesson will:
1. Navigate, select and use sketching and extrusion tools found on the Solid Works modeling interface.
2. Create a 3D solid model of a shaft collar .
3. Perform an extruded cut
4. Calculate Area and Volume of basic shapes and extrusions. These include the calculation of the area of rectangles, triangles, circles and the calculation of the volumes of these extruded shapes.
