Metal Matrix Composites (MMC) are novelly prepared with the reinforcement of different wood ash in the matrix material to achieve desired properties. Utilizing the waste material for reinforcement may reduce the material cost. Usually, fly ash from thermal power plants has become a popular reinforcement material for MMC through stir casting and employing in friction stir processing. This research is motivated by using ash of waste bamboo powder (AWBP). The waste of bamboo pieces was collected from the furniture industry. They have been gathered, prepared to ash and used as reinforcement of 4 wt%, 8 wt%, and 10 wt% in stir casting of aluminium alloy 7075-T651 and that was optimized as 8 %. The objective of this research is CNC turning type machinability of AA7075-T651/ B4C/AWBP hybrid Composites. The details of the reinforcement are 2 wt% B4C and 8 wt% AWBP. The effects of such reinforcement in AA7075-T651/ B4C/AWBP hybrid composite have improved the friction and wear behaviours, such as high wear resistance and low wear rate. The composite was cased as circular rods. The CNC turning type machinability was investigated in the CNC turning centre. The cutting speed varied from 1000 rpm to 3500 rpm, the feed rate varied from 100 mm per hour to 200 mm per hour. The Al2O3 nanoparticles concentration on cutting fluids varied from 0.25 wt% to 1 wt%. The response surface methodology was used to optimize the parameters. A mathematical model was developed to predict the responses.
