...material to create the hole. The Extruded Cut feature was named Cut-Extrude1. The Through All End Condition option created the Cut- Extrude1 feature from the Front plane. The Linear Pattern created an array of 9 holes, equally spaced along the length of the FLATBAR Part.

LINKAGE Assembly An assembly is a document that contains two or more parts. An assembly inserted into another assembly is called a sub-assembly. A part or sub-assembly inserted into an assembly is called a component. The LINKAGE assembly consists of the following components: AXLE part. SHAFT-COLLAR part. FLATBAR part. AIRCYLINDER sub-assembly. Establishing the correct component relationship in an assembly requires forethought on component interaction. Mates are geometric relationships that align and fit components in an assembly. Mates remove degrees of freedom from a component. Mate Types Mates reflect the physical behavior of a component in an assembly. The components in the LINKAGE assembly utilize Standard Mate types. Review the Standard and Advanced Mates types. Standard and Advanced Mates: The Mate PropertyManager displays Standard Mate Types and Advanced Mate Types. Components are assembled with various Mate Types. Copyrighted Material Copyrighted Material Copyrighted Material Copyrighted Material SolidWorks Tutorial 2005 PAGE 1 32 The Standard Mate Types are: Standard Mate Types: Coincident: positions selected faces, edges, and planes so they share the same infinite line. Positions two vertices so they touch. Parallel: positions the selected geometry so they lie in the same direction and remain a constant distance apart. Perpendicular: positions the selected geometry at 90º. Tangent: positions the selected items in a tangent mate (at least one selection must be a cylindrical, conical, or spherical face) Concentric: positions the selected geometry so that they share the same center point. Distance: positions the selected geometry at a specified distance between them. Angle: positions the selected geometry at a specified angle between them. The Mate, Show popup dialog box, displays the Pop-up toolbar during the Mate options. The Standard Mate Types, Aligned/Anti-Aligned, Undo and OK are displayed in the Pop-up toolbar. There are two Mate Alignment options. The Aligned option positions the components so that the normal vectors from the selected faces point in the same direction. The Anti-Aligned option positions the components so that the normal vectors from the selected faces point in opposite directions.

A Symmetric Mate does not create a Mirrored Component. Cam: A cam-follower mate is a type of tangent or coincident mate. It positions a cylinder, plane, or point to a series of tangent extruded Cam faces. The Cam profile is comprised of tangent lines, arcs, and/or splines in a closed loop. Gear: Positions two components to rotate relative to one another about selected axes. The axis of rotation includes: cylindrical and conical faces, axes, and linear edges. Gear components are not required for a Gear Mate. Example, two rolling cylinders. Limit: Defines a range of motion for a Distance Mate or Angle Mate. Specify a starting value, minimum value and maximum value. SolidWorks Help Topics list the rules governing Mate Type valid geometry. The valid geometry selection between components in a Coincident Mate is displayed in the Coincident Mate Combinations Table. SolidWorks Help Topics also display Standard Mates by Entity. Specific combinations of geometry create valid Mates.

Utilize a Coincident Mate between the SHAFT-COLLAR back face and the FLATBAR front flat face. The LINKAGE assembly requires the AIRCYLINDER assembly. The AIRCYLINDER assembly is located on the SolidWorks Tutorial Multimedia CD in the pneumatic components folder.
