The comparative strength study of spur gears made by CNC machining and 3D printing is investigated in this research. In order to evaluate the effects of both production processes on gear strength a crucial component that affects gear performance a 3D gear model has to be created. Tensile, geometrical error, surface roughness, hardness and microscope views are the five different experimental tests that are used in this study to determine the best way to increase gear strength. It is crucial to comprehend these approaches’ efficacy in order to optimise the manufacturing and gear design processes.
Aim
Develop an understanding of the manufacturability of polymeric gears using different manufacturing methods, such as additive manufacturing and CNC machining.
Objective
Gather gear geometry parameters and produce a 3D model suited for 3D printing.
Create a spur gear by using subtractive and additive manufacturing methods.
Conduct tests and experiments to evaluate the spur gear’s tensile strength, geometric accuracy, hardness, and surface finish.
Assess and compare the end results of the two manufacturing processes to identify the most efficient approach based on the properties of strength.
