ABB has launched a condition-based maintenance (CBM) service for fleet and individual robot assessments. It enables robot users to create a preventive maintenance schedule for individual robots or robot fleets based on real-time operational data, to optimise productivity and minimise downtime. CBM uses real-time data on robot operations to help identify any potential issues that could affect performance, including duty, speed, acceleration and gearbox wear. These variables are compared against other robots in ABB’s worldwide robot database to calculate the likelihood and time frame of a potential fault or failure. Aimed at customers with large fleets of robots, ABB’s CBM tool can provide advice on whether remedial action is required, involving either repair or replacement of affected parts.
