Solidworks Exercise Modeling the bearing block (40 minutes) Create the Main Base Rectangle • Draw a line snapped from the right quadrant of the circle to the right. • Connect another line from the end point and down, snapped even with the origin • Connect a third line from this endpoint to the origin (after the third line, click the right mouse  select end chain). Rectangle • Draw a line snapped from the right quadrant of the circle to the right. • Connect another line from the end point and down, snapped even with the origin • Connect a third line from this endpoint to the origin (after the third line, click the right mouse  select end chain).

Solidworks Exercise Modeling the bearing block (40 minutes) Create the Main Base Mirror • Holding down Ctrl, highlight the construction line and the three lines you just drew. • Hit the Mirror tool, or Tools, Sketch Tools, Mirror. • Dimension the overall width to 60mm. 60 Create the main base Mirror • If needed, have students drag a Mirror Tool Icon from Tools, Customize, Commands, Sketch Tools over to the right side toolbar. • Holding down Ctrl, highlight the construction line and the three lines you just drew. • Hit the Mirror tool, or Tools, Sketch Tools, Mirror. • Dimension the overall width to 60mm.

Solidworks Exercise Modeling the bearing block (40 minutes) Create the main base Trim • Click Trim (or tools  sketch tools  trim) and select the bottom half of the circle. Click to delete a quarter of the circle. • Repeat process to remove the other quarter of the circle Create the main base Trim • Click Trim (or tools  sketch tools  trim). Now point at the bottom half of the circle. A quarter of the circle will highlight. Click to delete. • Click on the other bottom quarter of the circle to trim. We have removed the bottom half of the circle.

Solidworks Exercise Modeling the bearing block (40 minutes) Make the main base Hole • Draw a circle anywhere and dimension it to 10mm • Using Add Relations, make it concentric with the top arch 10 Make the main base Hole • Draw a circle anywhere and dimension it to 10mm • Using Add Relations, make it concentric with the top arch

Make the main base • Hit the Extrusion key • Make End Condition Blind; and type in 15mm for distance ª Click OK and label this Main base.

Solidworks Exercise Modeling the bearing block (40 minutes) Make cbore • Go to isometric view and highlight a flat area on top of the part, then open a sketch on the plane shown. • Draw a circle anywhere and dimension it to 8mm. • Dimension it 7.5mm from both edges.  • Extrude Cut this sketch to 5mm • Label this Cbore 8 Make cbore • Go to isometric view (if isometric tool is not visible, go to view  toolbars  standard view) and highlight a flat area on top of the part, then open a sketch on the plane shown. • Draw a circle anywhere and dimension it to 8mm. ª Dimension it 7.5mm from both edges (click on the edge first).  • Extrude Cut this sketch to 5mm • Label this Cbore (click on cut-extrude in the feature tree and rename)

Solidworks Exercise Modeling the bearing block (40 minutes) Make the thru hole • Select the plane at the bottom of the cbore and open a sketch • Draw a circle anywhere and make it 5mm diameter • Use Add Relations to make this concentric to the cbore edge. • Extrude Cut a hole through all • Label this Hole Make the thru hole • Select the plane at the bottom of the cbore and open a sketch • Draw a circle anywhere and make it 5mm diameter • Use Add Relations to make this concentric to the cbore edge. • Extrude Cut a hole through all • Label this Hole

Solidworks Exercise Modeling the bearing block (40 minutes) Mirror the hole • Select Insert, Pattern/Mirror, Mirror Feature • Under Mirror Plane, select Right plane (or plane 3) in the feature manager; under Features to Mirror, choose Cbore and Hole in the feature manager • Leave this called Mirror1 Mirror the hole • Select Insert, Pattern/Mirror, Mirror Feature • Under Mirror Plane, select Right plane (or plane 3) in the feature manager; under Features to Mirror, choose Cbore and Hole in the feature manager • Leave this called Mirror1

Solidworks Exercise Modeling the bearing block (40 minutes) 15 Make a notch • Open a sketch on the Top plane (or plane 2) • Draw a circle centered on the bottom edge of the part • Dimension the circle at 6mm. Dimension the circle 15mm to the right of the origin (select the origin in the feature manager) • Select the Extrude Cut feature, and select a Blind cut of 15mm • Select OK and label this Notch 6 Make a notch • Open a sketch on the Top plane (or plane 2) • Draw a circle centered on the bottom edge of the part • Dimension the circle at 6mm. Dimension the circle 15mm to the right of the origin (select the origin in the feature manager; NOT by clicking on it) • Select the Extrude Cut feature, and select a Blind cut of 15mm • Select OK and label this Notch

Solidworks Exercise Modeling the bearing block (40 minutes) Cut top of notch • Rotate the part until you can see the end face of the previous cut • Select this plane and open a sketch • Select the entire half-circle face and select Convert Entities • Draw a construction line through the straight part of this half circle (parallel to the edge of the bearing block • Select Revolve Cut Feature, and rotate 90 degrees • Click OK and name this Notch Top Cut top of notch • Rotate the part until you can see the end face of the previous cut • Select this plane and open a sketch • Select the entire half-circle face and select Convert Entities • Draw a construction line through the straight part of this half circle (parallel to the longer edge of the bearing block). We will rotate about this line. • Select Revolve Cut Feature, and rotate 90 degrees • Click OK and name this Notch Top
