Screw Tightening and Load Check Function

In this video, we’ll go over how to use the screw tightening icon to automate fastening tasks with precision and flexibility. Whether you're building a new program or refining an existing one, this walkthrough will help you understand how to configure each step of the screw tightening sequence using FANUC’s intuitive interface.

We’ll start by creating a new program and adding the screw tightening icon to the timeline. From there, we’ll explore the default instructions included in the bracket and how to customize them based on your application. You’ll learn how to enable or disable pause contact stop, configure load check settings, and interpret the results to ensure your robot can handle the tightening force safely.

Next, we’ll dive into the configuration of key icons that support the screw tightening process:

• Force Push: Apply consistent pressure to the screw head using the integrated force sensor.
• External Output: Select and trigger the correct tightening schedule using output signals.
• Wait Icon: Ensure the robot waits for confirmation before starting the tightening process.
• Force Threading: Enable controlled threading when using tools without spring compliance.

Requirements for Setup:

• FANUC CRX-Series collaborative robot
• Tooling to perform tightening work (e.g. a screwdriver)
• Knowledge of torque limits, threading depth, and force control settings

What You’ll Learn:

• How to program and customize a screw tightening sequence
• How to configure a force control coordinate system
• How to interpret load check results and optimize robot posture
• How to manage threading operations without spring-loaded tools

By the end of this video, you’ll have a clear understanding of how to automate screw fastening tasks with confidence and precision. Sign in to watch and take your programming skills further.
