The goal of this project is to use CNC end milling operations to process AL 6063 composites reinforced with varying weight percentages of Nano TiO2 (1, 3 and 5). The composites are made using the stir casting technique in an electric melting furnace. Due to their superior wear and corrosion resistance, low density, and outstanding mechanical qualities as compared to other metals and alloys, aluminum alloys are utilized extensively in the aerospace and automotive sectors.For study and optimization using Taguchi's method, analysis of variance (ANOVA) was used to determine the importance of process factors on the response variable. Cutting forces and surface roughness are the factors that are taken into consideration during machining. Cutting forces and surface roughness have been examined for the CNC end milling study parameters, which include rotating speed, cutting speed, TiO2 addition content, end mill cutting edges number, depth of cut, and feed rate under dry lubrication conditions. To develop mathematical models for all parameters as functions of significant process factors, Response Surface Methodology (RSM) is applied. The results of analyses of variance indicate that the cutting force is best at the center level of rotating speed (25 m/min), low level of cutting speed (500 rpm), center level of the number of flutes on the cutting edges, and highest levels of feed rate and depth of cut.In accordance with the determined optimal level, experimental data is gathered, interest-area mathematical models are developed, and process model optimization is performed.
