FANUC FANUC Robot Applications & End-of-Arm Tooling 1 — Questions and Answers
Question 1: Which FANUC robot series is most commonly used for arc welding applications due to its slim arm and hollow wrist design?
- ARC Mate series (Correct answer)
- M-2000iA series
- LR Mate series
- CR-35iA series
Correct answer: ARC Mate series
The FANUC ARC Mate series is specifically designed for arc welding, featuring a hollow wrist for routing welding wire and cables through the arm.
Question 2: What is the purpose of a Force/Torque (F/T) sensor mounted at a FANUC robot's wrist?
- To measure contact forces and enable force-guided assembly, polishing, and insertion tasks (Correct answer)
- To weigh the workpiece for quality control only
- To calibrate the tool center point automatically
- To monitor joint motor temperatures
Correct answer: To measure contact forces and enable force-guided assembly, polishing, and insertion tasks
A wrist-mounted F/T sensor measures forces and torques in all six axes, enabling the robot to perform compliant assembly, surface following, and insertion operations.
Question 3: In FANUC spot welding applications, the term 'equalization' refers to:
- The servo gun automatically compensating for electrode wear and part thickness variation (Correct answer)
- Balancing the robot's payload to prevent joint overload
- Equalizing the current between two welding transformers
- Synchronizing two robots on the same part
Correct answer: The servo gun automatically compensating for electrode wear and part thickness variation
Equalization in servo spot welding means the gun self-adjusts its closing force and position to account for electrode tip wear and variable sheet stack thicknesses.
Question 4: Which gripper design is preferred for FANUC palletizing robots handling fragile or irregularly shaped objects?
- Vacuum (suction cup) gripper with multiple independently controlled zones (Correct answer)
- Two-finger parallel gripper
- Magnetic gripper
- Rigid mechanical clamp
Correct answer: Vacuum (suction cup) gripper with multiple independently controlled zones
Multi-zone vacuum grippers allow sections to be activated or deactivated independently, conforming to different product sizes and protecting fragile items from excessive force.
Question 5: What FANUC software option is used to automatically generate optimized palletizing patterns and positions without manually teaching each pallet layer?
- FANUC PalletTool (Correct answer)
- FANUC Line Tracking
- FANUC Coordinated Motion
- FANUC iRCalibration
Correct answer: FANUC PalletTool
FANUC PalletTool software generates complete pallet layer patterns and robot positions from user-defined box dimensions and pallet size, eliminating manual position teaching.
Question 6: When a FANUC robot performs a dispensing or sealing application, which motion type is most commonly used to maintain consistent bead width?
- Continuous path motion (CNT=100) with constant speed override (Correct answer)
- Point-to-point (FINE) joint motion between each seam segment
- Free-running joint interpolation
- Cartesian step motion with manual triggers
Correct answer: Continuous path motion (CNT=100) with constant speed override
Continuous path motion with CNT=100 blends move segments smoothly and maintains constant TCP speed, which is critical for producing a uniform material bead width.
