Development of Simulation: for an Adaptive Control Machining System Srinivasa Prasad Balla

In any machining process the economic objective is to maximize the metal removal rate by the highest possible feed rate under the constraint of tool breakage. An NC Program merely guides and controls a Machining process. It cannot respond and react to variations in machining conditions during the operation. Machining force regulation and tool wear are challenging problems since the force and temperature rise varies significantly under normal operating conditions. In order to overcome above mentioned problems, the concept of ADAPTIVE CONTROL MACHINING was introduced. Adaptive Control system (AC) maximises material removal rates and minimises cycle times by optimizing the cutting feed rate based on a controlled spindle load. In accordance to the results obtained, the application of Adaptive control principles to TURNING is aptly justified. As part of this work, a simulation is developed for turning process based on adaptively controlled experimental data.
