A key technology stream that is being utilised at Additive Automations is force control; this robotic control method facilitates robotic finishing of AM parts as it allows the disadvantages of robots, compared with traditional machining centres, to be overcome.
The fundamental philosophy of force control, is that the end-effector control system is designed not to track a motion trajectory alone, but rather to include motion tracking and mechanical impedance regulation. This offers the robot a holistic view of the process, or in other words ‘perception’.
Within our automation cell we deploy a new type of force control algorithm to ensure that all engineering surfaces are finished to the required specifications. This is achieved by monitoring key metrics and inferring the correct control corrections.
