Process force and technology model for designing and controlling finishing operations with rotating grinding tools

Today the technological design of fine machining processes like finishing of plane surfaces is still a procedure based on experience. In addition, finishing technology is the result of an empirical approach. Innovative methods for designing and controlling finish operations make use of models and the implementation of procedures that allow the derivation of optimal technological parameters and process control strategies as well as the prediction of cutting behaviour of abrasive tools. These process and technology models are based on measuring and evaluating process variables like process forces or cutting torque and parameters of the electric drive like motor current or torque. With these models a finishing process is achieved on the basis of mathematical and technological principles wherein the grinding tool works in a self-sharpening condition providing optimal results.
