Robotized processing is important for sanding, grinding, polishing, deburring, etc. since a consistent contact force is crucial for the final product quality. However, human workers are not able to perform such a consistent contact force over longer time. Furthermore, experts for these 3D jobs (dirty, dangerous and demining full) are increasingly hard to find. Consequently, all industries (aerospace, automotive and general industry) tend to automate their surface finishing sequences.
Key criteria for a reproducible, uniform surface finish is to control the process and therefore the process force. Previous approaches have been either force control or physical compliance. The state of the art approach combines the benefits of both principles and results in an active compliant force control.
An autonomous sensitive compliant force control not only allows to controlling the forces but also compensate a certain range of positioning tolerance. Through this physical compliance the contact force can be controlled very fast. It has a further impact on the usability. Within a self-adapting stroke, the robot paths may be programmed rather inaccurately.
Robotics applications based on active compliant force control deliver a consistent high-quality production, high process security and a faster return on investment. Best practice cases are e.g. paint sanding, preparation and spot repair or grinding of aluminium turbine parts and turbine blades.
