Analysis and Modeling of Delamination Factor in Milling of JFRP Composite Using Central Composite Design

Nowadays, JFRP composite is known as an eco-friendly, cost-effective, lightweight, higher stiffness product and the demand for this composite is increasing tremendously in various applications like automotive, aerospace, marine, and domestic upholstery. In order to achieve the required shape and design of this composite, machining is essential during the assembly stage. Thus, machining arises some difficulties in where the delamination factor is one of the major drawbacks during the machining of the milling process. The cutting parameter of machining influences on the output performance of the product. The main aims of this study are to find out the effect of milling parameters such as feed rate, spindle speed, depth of cut on the output response of the delamination factor which generates during milling on JFRP composite. The machining was done by using a solid carbide cutting tool of 8 mm width and the experiments were conducted according to the CCD. A mathematical model also developed in this study to correlate the milling parameters with the output parameter of the delamination factor.
