Optimisation of machining parameters by criterion of maximum productivity

The optimisation of machining parameters for machine tools using the criterion of maximum productivity rate is not a new problem – many unresolved issues remain. The intensification of machining processes leads to changes in the productivity rate; analytically defining optimal machining parameters for the maximum productivity rate in real-world manufacturing processes is, therefore, an important problem that needs to be addressed. This paper aims to formulate a mathematical model for the optimisation of cutting processes on machine tools based on the criterion of maximum productivity rate. The mathematical model is based on technological data, machining and reliability parameters of the machine tool units. Several practical applications are discussed.

Investigation of Core Thickness Undersized on Composite Panels

The purpose of this study is to investigate the core thickness undersized problem which is very common with honeycomb core cutting. These defects occur during the honeycomb core cutting by using core block saw machine. There are number of variable causes of the defect. The author is use statistical approach to identify critical variable causing of this defect. There are use two method of the quality tool such as Ishikawa Diagram and also Five Why Method. However the revolutionary read of core thickness undersized is collected to analyze. Minitab software is used for the analysis propose and certain improvement are suggested.The defect is occurred during the during the core block saw cut the core block to be a slicing.
