Abstract—The multiple saw's feeding system includes an auxiliary motor that drives the wheel and track in the workbench. Buffing wheels and chain pieces on the track provide stable holding of the log for structural stability. The mechanical factors cause cutting defects, which requires investigation of relative phenomena. Multiple engineering analyses enable quantitative mastering of related aspects to reach the solutions. The designer checked the chain's motion and adjusted the shape of the pieces to avoid the collision. The uneven shrinkage of casting samples improved after mold redesign. The chassis's deformation reduced through rib placed on the roller seat and frames. The modal analysis revealed the possible swing, which also affects the quality of the sawing. The frequency adjusting avoids the amplifying due to the excitation of motors. Changing the thickness of the chassis and increase the diagonal reinforcing bar could reduce the twisting amplitude. The case study confirms creatively utilized multiple engineering analyses with simplifying modeling skills benefits in system improvement.
