Performance and deformation behavior of a master jig on circular saw machine using finite element method

This study investigates the performance, stress distribution, deformation and potential failure modes of a newly developed Master Jig (MJ) designed for circular saw machine operations. The MJ comprises three components: the master jig body (MJB), the master jig accessories (MJA) and the master jig guide (MJG). The jig was modelled and simulated under applied static loads of 520 N and 600 N using SOLIDWORKS software. The MJ performance was evaluated, results were recorded, and a deformation graph was presented and shape displayed in true and defined scales of 0.135238 and 0.036047, respectively. The analysis shows that, maximum directional deformations at 520 N and 600 N were 8.463 x 102 mm and 3.197 x 103 mm respectively, elastic strains at 6.540 x 10 and 1.433 x 10, von mises stresses at 2.580 x 106 MPa and 3.930 x 107 MPa respectively, the Yield Strengths at 2.000 x 107 MPa and 3.930 x 107 MPa respectively, and the factor of safety at 31 and 11 respectively. The study underscores the potential of finite element modelling in the predictive design of woodworking jigs.
