Principle of six point location (3-2-1)
Understand the Problem
The question is asking for an explanation or description of the Principle of Six Point Location, specifically the 3-2-1 method, which is often used in engineering or manufacturing for defining the proper location and support of a part or object. This principle helps in ensuring that a workpiece is correctly positioned and secured for machining or measurement operations.
Answer
The 3-2-1 principle is used to restrict a workpiece's movement along six degrees of freedom using six points of contact.
The 3-2-1 principle, also known as the six-point location principle, is a method used to restrict the movement of a workpiece along six degrees of freedom: three translational and three rotational. It uses three points of contact on the primary plane, two on the secondary, and one on the tertiary.
Answer for screen readers
The 3-2-1 principle, also known as the six-point location principle, is a method used to restrict the movement of a workpiece along six degrees of freedom: three translational and three rotational. It uses three points of contact on the primary plane, two on the secondary, and one on the tertiary.
More Information
The principle effectively uses a geometric strategy to provide stability and precision by locking the workpiece into a fixed position during machining or assembly processes.
Tips
A common mistake is not understanding the concept of degrees of freedom. Each point of contact reduces one degree of freedom, preventing unnecessary movement of the workpiece.
