An adaptive control optimization for circular sawing

This paper describes a method of adaptive control optimization developed for circular sawing to produce a specified surface finish quality in a production environment. It is possible to develop the relationship between the workpiece feed-rate and acoustic emission (AE) count-rate, which is used for the automatic control of workpiece feed-rate, by a single cutting test. This is done for the workpiece immediately before operation by adaptive control optimization, with the workpiece feed-rate and AE count-rate chosen as control variable and process variable, respectively. A multiple-regression equation based on AE count-rate and specific gravity for softwoods is effective for adaptive control optimization of circular sawing in order to produce the required surface finish quality.
