Optimization and sensitivity analysis of drilling parameters for sustainable machining of carbon fiber–reinforced polypropylene composites

Abstract

Machining processes face two major challenges: sustainability and cleaner production. However, the effective utilization of tool and methods of lubrication system in sustainable machining have been dealt in depth in earlier investigations. This work aims to optimize sustainable machining parameters in drilling process for recyclable carbon fiber-reinforced polypropylene (CFR-PP) composites. This work is focused on modeling and optimization of drilling parameters for sustainable machining with respect to thrust force and torque for CFR-PP composites. The response surface method based on D-optimal design of experiments is used for modeling and optimization with variables such as drill spindle speed and drill feed rate as numerical factors, which includes different drill material as the categorical factor. The influences of tool materials on the sustainable machining are also discussed in detail. Further, the sensitivity analysis is applied to compare the relative impact of control parameters (spindle speed, feed rate, and drill materials) on thrust force and torque. The scanning electron microscope images are used for analyzing the morphologies of drilled surfaces.

Optimization and Sensitivity Analysis of the Cutting Conditions in Rough, Semi-Finish and Finish Honing

“…They found that the weights used in the multi-objective optimization process influence the prediction variance. Mudhukrishnan et al [ 28 ] optimized drilling parameters, such as spindle speed, feed and drill material, with respect to thrust force and torque, and performed a sensitivity analysis to assess the impact of control variables on the responses.…”

“…1−3 They are fantastic tools to strengthen any study dealing with varying parameters, as they allow weight to be given to all observations and trends in order to enable the pinpointing of optimal conditions. DoE have been used extensively in a very wide range of fields, from mechanical engineering 4,5 to numerical simulations. 2 The pharmaceutical, 6 medical, 7 and chemical engineering 8−12 fields also make broad use of DoE in their research.…”

Manufacturing of composite materials with high environmental efficiency using epoxy resin of renewable origin and permeable light cores for vacuum-assisted infusion molding

“…Entre otras, un inconveniente crítico de estas fibras está relacionado a los costos y condiciones de producción como, por ejemplo, que las CF requieren temperaturas extremadamente altas para obtener fibras altamente purificadas. Por otra parte, estas fibras de refuerzo convencionales tienen un impacto ambiental importante, relacionado a las etapas de producción y la problemática luego de su vida útil; esto significa que su producción en masa es prácticamente inviable [10,11].…”
