Concept of Degrees of Freedom in Assembly || Autodesk Inventor Basics

In this tutorial we will learn what ‘Degrees of Freedom’ (DOF) of component is and how it is utilized/controlled in Assembly environment.

In Autodesk Inventor each ungrounded component in the assembly can be moved in six directions. It can move along X, Y, and Z axes (translational freedom) and it can rotate around the X, Y, and Z axes (rotational freedom). By turning on Degrees of Freedom (DOF) we can examine the movement of the component in the assembly. We can remove displayed DOF, by using constrains.
In this video we are taking a very simple example to explain all the concept.

1. Create a new assembly file with an English Template.
2. Place a new component in the assembly.
3. Newly placed component can be grounded at origin.
4. Activate Degrees of Freedom command.
5. Grounded Component has no Degrees of Freedom.
6. When we un-ground the component then 6 DOF is visible in front of us.
7. Activate Degree of Freedom Analysis command.
8. This dialogue box shows that the components has 3 translation freedom and 3 rotation freedom along X, Y, and Z axes.
9. We can animate the component from here to examine its probable movement.
10. To remove displayed DOF we will apply mates.
11. After applying a single assembly mate 3 translation DOF were removed.
12. Now we will apply another assembly mate to remove two more rotational DOF.
13. Currently only one rotational DOF is left, that is what we require.

Note:-

The video has a little caption assistance, but I have given sufficient amount of pause over the tool and their tip, so that they can be read easily. In addition this, annotations are also applied over important places…. so please focus on them to understand what is being done and how….

Concept of Degrees of Freedom in Sketches || Autodesk Inventor Basics

 

In this tutorial we will learn what Degrees of Freedom (DOF) is and how it is utilized in 2D sketch environment to fully constrain a sketch.

In Autodesk Inventor our ultimate goal in creation of 2D sketch is, a fully constrained sketch. This means the position of drawn sketch cannot be changed without any deliberate action. By turning on Degrees of Freedom (DOF) we examine how the geometry can be moved in an active sketch. We can remove displayed DOF and lock the sketch, by adding sketch and dimensions constraints.

In this video we are taking a very simple example to explain all the concept.

1. Create a new part file with an English Template.
2. First of all we will start a new 2D sketch.
3. Project the X and Y axis in the active sketch and convert them into construction geometry.
4. Draw a rectangle free hand in the design window.
5. Activate Show All Degrees of Freedom command.
6. Currently the software denotes degrees of freedom of the sketch with red marks and mentions that 4 dimension are needed to fully constrain the sketch.
7. Next we will apply some sketch and dimension constraints to fully constraint the sketch as well as lock its movement.
8. As we apply the constraints and dimension the red marks will disappear in relation with it, which will result a lock in its moment also.
9. Now you can see there is no red marks of DOF and the sketch is fully constrain
