Let us begin by understanding Six Degrees of Freedom.
Tool design is all about Six Degrees of Freedom.
and rotation about its axis: namely rotation about XY axis; XZ axis and YZ axis.
Therefore totally it is six degrees. In tool design, the part or component has to be arrested in all the six degrees of freedom.
Let us take an example.
Let us take a rectangular block It has got six faces.
Six degrees of freedom are:
First is XY plane: Bottom face
Second is XZ plane is: left side face or right side face and
Third is YZ plane is either top side or bottom side.
We will see in detail.
