Modelling and simulation of a tenoning jig to predict performance and failure mode on circular saw machine

Abstract

This research predicts the performance and failure mode of a developed tenoning jig (TJ) used on the circular saw machine. TJ developed consisted of a double-based adjustable medium density fibreboard (MDF) with an area of 100 × 200 mm2, side panel of equivalent length and a height of 114 mm2. SOLIDWORKS software, 2021 was used to model and simulate the jig applying a static load of 500 N. The jig performance was evaluated, results were recorded and deformation shape presented in true and defined scale of 1160.89. The analysis shows maximum directional deformation at 2.342 × 10-2 mm, equivalent elastic strain at 1.245 × 10-4, stress and yield strength at 2.580 × 106 N/m2 and 3.930 × 107 N/m2, respectively, with the factor of safety at 15. The jig offers cost-effectiveness with an estimated manufacturing cost of US$43.123 as of 2021. This research enhances safety in circular saw operations, minimising risk and improving the overall woodworking process.
