GF Machining Solutions’ Autonomous Mobile Robots (AMRs) deliver a smart, unmanned and automated factory solution that enhances manufacturers’ production processes

Coventry-based GF Machining Solutions, the milling, EDM and laser ablation machine tool specialist, and advanced tooling and automation system solutions provider, has introduced a ground-breaking automation solution designed to help manufacturers reduce production lead times and improve operational efficiencies. The company’s Autonomous Mobile Robots (AMRs) streamline materials handling and the transfer of workpieces, tooling and electrodes between individual cells, such as milling, WEDM, die-sink, washing and inspection, ensuring production processes operate smoothy and more effectively, which in turn facilitates lights-out operation.

Martin Spencer, GF Machining Solutions’ UK managing director, said: “AMRs automate and connect different manufacturing processes. They interface, seamlessly, with other robots and automation systems and different manufacturing cells and are specifically aimed at manufacturers operating in high-mix, low-volume environments.”

AMRs are similar to AGVs (Automated Guided Vehicles) — but there are important and fundamental differences between the two. AGVs are robots that follow fixed paths or tracks in a workshop/factory for material transportation and typically require magnetic tapes, sensors or wires to facilitate their movement. AGVs have minimal onboard intelligence and can only follow simple programming instructions. They can detect obstacles but cannot move around them — so they stop until the obstacle is removed. Changing fixed and predetermined routes for AGVs involves additional costs and production flow disruptions.

Sophisticated software
Meanwhile, AMRs are a more sophisticated, safe, flexible and efficient automation solution that operate autonomously. They can navigate their way around uncontrolled environments without the need for fixed paths or tracks. Using cameras, sensors and laser scanners along with sophisticated software to create maps, AMRs can detect obstacles and safely manoeuvre around them by choosing the best alternative route. This results in accident-free environments and ensures that material flow remains uninterrupted, optimising productivity.

Until recently, traditional AGVs were the only option for automating internal transportation tasks. AGVs are a familiar fixture in large, fixed installations where there is a need for repetitive, consistent material deliveries, and where large initial cost outlays and long return on investment (ROI) can be tolerated.

AGVs are now being challenged by the arrival of more sophisticated, flexible, and cost-effective AMRs which can perform a variety of tasks at different locations with simple software adjustments. They can be controlled via their interface or configured through fleet control software. This software can prioritise orders and assign tasks to AMRs based on their position and availability.
