Abstract

Wood machining is a cutting process of wood using a machine in which there are blades, sawing, planning, shaping, profiling, turning, sanding, and etc. Nowadays, in Indonesia surface roughness quality measurement of wood has not been available yet, while the available standards are based on the experience of operator or industrial furniture. The aim in this research is to contribute in providing of the surface roughness standard that does not exist yet. In this research, the tests are conducted using modified CNC TU-3A-machine to investigate the effect of belt speed (m/s) and feed rate (mm/min) on the surface roughness of wood (tembesu). The tests were focused on sanding process with grain size grit 180. The CCD (Central Composite Design) as DOE (Design of Experiment) was used as reference for belt speed (6.55, 8, 11.5, 15 and 16.45 m/s), feed rate (35.86, 40, 50, 60 and 64.14 mm/min). The depth of cut was maintained constant at 1.5 mm. Measurements of surface roughness utilized surface tester Accretech Handysurf E-35 A/E. The surface roughness (Ra) was measured at 3 different positions on the workpiece. The results show that values of Ra are 1.967 μm and 1.020 μm for maximum and minimum respectively. As the conclusions of this research, it is obviously to recognize that the higher is the belt speed, the lower is the surface roughness (Ra). In contrary, the increasing of the feed rate will affect to higher or surface roughness (Ra).
