Title: Effect of Friction Welding on tensile strength of Polymethyl Methacrylate (PMMA) by Computerized Numerical Control Machine
Abstract: The objective of this research is to investigate the effect of joining parameters from friction welding process of polymethyl methacrylate on the mechanical properties. Friction welding used lathe computer numerical control machine of applied for welding. Friction welding used different rotation speed such as 600, 1000, 1400, and 1800 rpm; burn of length was 2.2 and 3.2 mm and welding time is constant at 30 seconds. From the investigation, the rotation speed and burn of length parameter influence mechanical properties. The lower rotation speed provides the higher tensile strength. The results showed that the condition with rotation speed at 600 rpm, burn of length at 3.2 mm, and welding time at 30 seconds provides the maximum average tensile strength of 18.11 MPa. In addition, the faster rotation speed causes the lower tensile strength. On the other hand, an increase of burn of length led to higher tensile strength.
