ADAPTIVE CONTROL IN GRINDING. WHY AND HOW -

1987-1-1  A model for a specific cylindrical grinding process is adopted based on dynamic characterization of grinding wheel and lubriciation condition. The grinding forces and surface roughness are evaluated. The small differences with experimental data are explicitly stated and together analysed in context of adaptive control.

Direct adaptive control of plunge grinding process

1995-10-1  It is also quite evident that the modelling of grinding process as a function of grinding conditions is a key in planning or adaptive control of the grinding operations. Since many factors influence the process, an accurate and rich database is required in process planning and selection of reference levels in adaptive control of grinding operations.

A control-oriented model for the cylindrical grinding

2009-1-9  This paper proposes a control-oriented model for the cylindrical grinding process in the state-space format. Existing models of the grinding process contain, either explicitly or implicitly, several dynamic relationships among various process variables, based on which a nonlinear state-space model can be derived. After a series of experiments are conducted to confirm the dynamic relationships ...

Advanced Process Control of grinding flotation in ...

Usually, the grinding circuit contains at least two interconnected mills with material classifiers (e.g. cyclones) separating the fine material from the coarse (that then goes for regrinding). The process is energy intensive with power consumption of roughly 20 to 30 MW and feed throughputs of 2,500 to 3,000 t/hr. Process variables are mill loads, motor torque and power, plus pressures and flow rates.
