Factors Affecting
Grinding Process Conditions
The process output variables of grinding processes are governed by a number of operation parameters, material conditions as well as the machine parameters. The following shows the schematic of the input-output relationship. Therefore, it is very difficult to have one model describing all the relationships.
Autonomous
Hierarchical
Modeling of the Process
In order to capture the input-output relationships effectively, the following hierarchical structure is used via the autonomous learning scheme developed. This structure allows for model building based on a few designed experiments.
Results of the
Generalized Modeling
An illustrative example of the modeling result by the developed modeling scheme is shown for surface roughness conditions of a surface grinding process. Overall, excellent predictions are achieved.
Output surface of
the Developed Fuzzy Basis Function Network Model
An illustrative example of the maximum residual stress model developed using a fuzzy basis function network is shown below. This illustrates that the model can represent the nonlinear relationships of unknown and uncertain processes.
