Some industrial applications use _________ for parts orientation.

Some industrial applications use _________ for parts orientation.

• A. One
• B. Two
• C. Three
• D. Four

Answer: (B)

Orientation in many automated setups is achieved by using two locating features. Two fixed reference points give a stable, repeatable way to position and align a part as it moves through the line. With two contacts, the part is constrained in two translational directions and its posture becomes predictable from cycle to cycle, which is usually enough for downstream operations like gripping or guiding by a vision system. Using only one reference point would still allow rotation around that point, leading to misalignment, while using three or more references can over-constrain the part and complicate fixturing. So two points strike a practical balance: simple, fast, and reliable for consistent part orientation in many industrial applications.
