FANUC FANUC Robot Applications & End-of-Arm Tooling 3 — Questions and Answers
Question 1: What does the FANUC payload identification routine determine, and why is it important?
- It measures the mass and center-of-gravity of the tool and part to optimize motion dynamics and protect motors (Correct answer)
- It sets the maximum allowable joint speed
- It calibrates the zero-position of each joint encoder
- It verifies network communication speed between controller and robot
Correct answer: It measures the mass and center-of-gravity of the tool and part to optimize motion dynamics and protect motors
The payload identification routine uses controlled test motions to measure the actual mass, center of gravity, and inertia of the EOAT, which the controller uses for accurate torque management.
Question 2: Which FANUC feature allows a robot to continue producing parts during a scheduled downtime by automatically switching between two fixtures?
- Dual Fixture / Synchronized I/O mode allowing one fixture to be loaded while the other is being processed (Correct answer)
- FANUC Restart from Alarm function
- Coordinated motion between two robots on the same part
- PalletTool automatic layer switching
Correct answer: Dual Fixture / Synchronized I/O mode allowing one fixture to be loaded while the other is being processed
Dual fixture setups with synchronized I/O allow an operator to unload/reload one fixture while the robot works on the other, achieving near-100% spindle or processing uptime.
Question 3: In FANUC vision-guided bin picking, what challenge does '3D area sensor' technology solve compared to 2D vision?
- It provides depth information to locate randomly piled parts in three dimensions, enabling the robot to plan a collision-free grasp pose (Correct answer)
- It replaces the robot's joint encoders
- It measures surface finish quality of machined parts
- It identifies part color and brightness only
Correct answer: It provides depth information to locate randomly piled parts in three dimensions, enabling the robot to plan a collision-free grasp pose
3D area sensors capture point-cloud depth data so iRVision can determine the exact 3D position and orientation of randomly stacked parts for successful grasping.
Question 4: What FANUC setting ensures that the robot follows the programmed path accurately even at high speeds, rather than cutting corners between waypoints?
- Setting the termination type to FINE instead of CNT for critical path segments (Correct answer)
- Increasing the motion group count
- Enabling JOINT interpolation on all moves
- Setting OVR to 100%
Correct answer: Setting the termination type to FINE instead of CNT for critical path segments
A FINE termination type forces the robot to decelerate to a complete stop at each programmed position, ensuring the TCP passes exactly through that point before continuing.
Question 5: Which FANUC robot series is specifically designed for heavy payload palletizing tasks exceeding 500 kg?
- M-2000iA series (Correct answer)
- LR Mate 200iD series
- CR-35iA collaborative series
- ARC Mate 120iD series
Correct answer: M-2000iA series
The FANUC M-2000iA is designed for ultra-heavy payloads, with the M-2000iA/2300 model handling up to 2,300 kg, making it ideal for automotive body-in-white and heavy casting applications.
Question 6: In FANUC arc welding, what is the purpose of the 'Weave' instruction in the TP program?
- To oscillate the welding torch laterally across the joint to improve fusion on wide or beveled weld joints (Correct answer)
- To pause the weld at each waypoint for inspection
- To switch between MIG and TIG welding modes
- To reset the wire feeder speed at the start of each pass
Correct answer: To oscillate the welding torch laterally across the joint to improve fusion on wide or beveled weld joints
The Weave instruction causes the torch to oscillate side-to-side along the weld path, distributing heat and filler metal across wider joint gaps for better fusion and fill.
