Deck 5: End-Of-Arm Tooling

Question 1

_____ grippers have fingers that hinge or pivot on a point to move the tips of the fingers.

A) Angular
B) Parallel
C) Magnetic
D) RCC

Answer 1

A

Question 2

How does a Venturi valve work?

Answer 2

For these systems,we pass compressed air through a conical Venturi orifice,as the air passes from the restriction to the larger area,the pressure falls and the velocity increases.Because of the large difference between the conical restriction and the line after it,an intense reaction is created that sucks the stationary air out of the area of the vacuum cup or wherever the air opening is attached into the main line after the Venturi valve.

Question 3

What is the difference between active and passive RCC units?

Answer 3

Active RCCs have sensors inside the unit to detect how much side shift is occurring,whereas passive RCCs use springs and shear plates.

Question 4

Active remote center compliance systems ____________.

A) incorporate sensors into the system for feedback
B) use shear plates and springs to allow for part misalignment
C) are part of an open-loop control system
D) All of these are correct

Question 5

Two finger grippers are good for ________________.

A) side-to-side centering
B) centering a part in two directions at once
C) odd-shaped parts
D) long parts

A(n) ___________ is a tube-like tool that people or robots use to direct the electrically charged wire used during welding operations.

A) X-type gun
B) C-type gun
C) RCC- type gun
D) welding gun

Question 7

What is the difference between angular grippers and parallel grippers?

Question 8

MIG welding systems use ___________ to fuse parts.

A) intense beams of light
B) electricity and feed wire
C) high-frequency vibration
D) current passing from one tip to the other

Question 9

A(n) ___________ for spot welding consists of a fixed tip and a movable welding tip.

A) X-type gun
B) C-type gun
C) RCC- type gun
D) welding gun

Question 10

How do vision systems help with part misalignment or variance in parts?

Question 11

Which of these is where we consider the mass to be centered and all forces in equilibrium?

A) Normal force
B) Safety factor
C) Center of gravity
D) RCC

A) Magnetic
B) Balloon
C) Vacuum
D) Pin

Question 15

Describe the process of spot welding.

Question 16

_____ grippers have fingers that move in straight lines toward the center or outside of the part.

A) Angular
B) Parallel
C) Magnetic
D) RCC

Question 17

____________ grippers work by using inflation or deflation to grip the part.

A) Magnetic
B) Balloon
C) Vacuum
D) RCC

Question 18

________ is the force that an object pushes back with when acted on by a force.

A) Friction
