Determination of optimal parameters in drilling composite materials to minimize the machining temperature using the Taguchi method

This work aims to determine the best combination of drilling parameters which results in the smaller temperature during the bone drilling procedure. An experimental procedure was adopted with the acquisition of two biomechanical blocks from Sawbones (composite material) with similar properties to the human bone. The goal of this experiment resulted in a drilling process to assess the generated temperature on the drill bit and simultaneously on the bone material. The Taguchi method is a powerful tool in high quality system design, and proved that can be used as optimization method to determine the best parameters combination to obtain the minimum temperatures in the drilling process.
